INTRODUCTION
The 530B Series is a high performance, dual voltage versatile DC motor control which provides a wide range of standard features,
with many options that extend its capabilities. The 530B Series will operate 1/8 through 1.0 horsepower at 115VAC input, and 1/
4 through 2.0 horsepower at 230VAC input. A chassis only model is available to operate a 1.5 horsepower motor at 115VAC input,
or 3.0 horsepower at 230VAC input. Reference “Basic Model Selection” guide.
The 530B Series consists of three basic types:
C= Chassis mounted, no enclosure, no power relay's.
RC = Chassis mounted, no enclosure, with power relay's.
RE = Plastic enclosure with power relay's - Nema 4/12 standard.
The 530B Series is designed for Permanent Magnet, Shunt Wound, and some Universal Series (AC/DC) motors in the above
horsepower ranges. The 530B Series incorporates transient voltage protection with adjustable Current Limit and AC fuses for
protection. Minimum and Maximum speeds are easily adjusted by trimpots, as is the I.R. Compensation. Acceleration and
Deceleration are fully adjustable via individual trimpots.
COMMONLY ASKED QUESTIONS
Q. Can I run two or more motors from the same drive?
A. Not recommended. The I.R. Compensation (regulation) and Current Limit circuits would have difficulty sensing the different
load on each motor.
Q. Can I change the horsepower of my motor and still use the same control?
A. Yes, provided you do not deviate outside the horsepower range for the voltage you are using. The trimpots would need
readjustment; see “Trimpot Chart” for approximate settings.
Q. Can I use the 530B Series as a Current Follower?
A. Yes, there is a field installable -5 or -7 option shown in "Options" section.
Q. Can I use the 530B Series on Tachometer feedback?
A. Yes, see +Tach (P2-9) under “Terminal Strip Wiring - P2”.
Q. Can I use the Stop (P2-11), Start (P2-13), and Common (P2-12) to stop-start the control on the “C” chassis version?
A. No. Terminals P2-11, P2-12, and P2-13 are only active on the relay versions; “RE” and “RC”. These terminals are
non-operative on the “C” version.
Q. Can the 530B Series be used as a Voltage or Tachometer Follower?
A. Yes. The voltage must be ungrounded and no more than +12 VDC (See “Terminal Strip Wiring” for proper hook-up).
Q. How would I proceed to stop/start the 530B Series with my own relay?
A. You can use the contact of your relay in place of the AMP REF to REV 1 (P2-2 to P2-7) jumper wire. Since this is a low
level signal (12 volts at 2mA), you must use a logic type relay (preferably gold contacts). This cannot be done on controls
using some options. Consult your Dart Representative if options are involved.
Q. Why is a jumper wire between AMP REF (P2-2) and REV 1 (P2-7) needed on drives with no options?
A. REV 1 (P2-7) and REV 2 (P2-8) are two identical stop inputs. One of these must be held low (to Amp Ref P2-2) for the control
to run. If the drive has no options, this must be jumpered to satisfy the “OR” gate. This requirement is satisfied by some
options. For these options, a connection must be made to these terminals. Instead of a jumper wire, the option is wired
to these terminals. (See “Jumper Wire Selection”).

CONTROL FEATURES
INPUT VOLTAGE SELECTION SWITCH - Switch selectable between 115 VAC and 230 VAC input.
MIN SPEED - (Minimum speed) Allows adjustment of the motor speed when the speedpot is set at minimum. This permits the user
to eliminate the “Deadband” on the main speed control, permitting zero calibration. Clockwise rotation of the “MIN” trimpot
increases output VDC.
ACCEL - (Acceleration) Allows adjustment of the motor acceleration from a minimum of 0.3 seconds to a maximum of 12 seconds.
The -15A option extends the maximum acceleration time to 30 seconds.
DECEL - (Deceleration) Allows adjustment of the motor deceleration from a minimum of 0.6 seconds to a maximum of 12 seconds.
The -15A option extends the maximum deceleration time to 30 seconds.
MAX SPEED - (Maximum speed) Allows adjustment of the motor speed when the speedpot is set at maximum (CW). This permits
the user to eliminate the “DEADBAND” of the speedpot, providing full speed at maximum rotation. Rotation of the “MAX” trimpot
in the clockwise direction increases maximum output VDC.
I.R. COMP - (Speed Regulation) Allows adjustment of the circuitry that
controls the speed regulation of the motor. This feature controls
armature speed by changing the armature voltage to compensate
for increased or decreased motor loading. Clockwise rotation of the
“I.R. COMP” trimpot will increase gain compensation.
CUR. LIM. - (Current Limit) Provides protection from excessive arm-
ature current by limiting the maximum armature current the control
can provide. This enables adjustment of the maximum torque the
motor can deliver. Set Current Limit (CUR. LIM.) at 125% of the rated
motor current. Clockwise rotation of the “CUR. LIM.” trimpot increas-
es the torque (current) the control will provide.
TACH INPUT SELECTION - Factory set at 3V per 1000 RPM, jumper
selectable (JU3) to 7V per 1000 RPM. Refer to “Tach Feedback”
section in “Control Modifications” for more information.
TERMINAL STRIP P1 - Barrier type terminal strip provides for connec-
tion of AC lines, motor leads, motor field (if necessary), and earth
ground.
TERMINAL STRIP P2 - Barrier type terminal strip provides for connec-
tion of speed potentiometer and any accessories and/or jumper
wires which control the drive.
RELAY - (Power Interrupt Relay's) Available only on the “RC” and the
“RE” versions, the relay's permits the switching of AC power with a
low current signal. For the “RE” version, the relay's will not allow start
up after power failure without manually restarting.

530B Series
TERMINAL STRIP WIRING - P1
CAUTION: BE SURE CONTROL HOUSING IS PROPERLY GROUNDED.
The 530B Series uses a 7 position barrier type terminal strip to handle the power connections.
P1-1 (EARTH GROUND) - Ground the control by connecting the ground wire to this terminal. NOTE: Terminals P1-5 (-ARM)
and P2-2 (AMP REF) are electrically the same, which is the common reference point (low voltage common) for the control
logic. The EARTH GROUND terminal (P1-1) is electrically different from common. If connected together, either at the
amplifier or in any other fashion, fatal or hazardous operation may occur and permanent damage to the control WILL result!
P1-2 (AC1) 115VAC - Connect incoming hot AC (black wire) to this terminal. NOTE: This is fused (F1) on the control.
(AC1) 230VAC - Connect either hot side.
P1-3 (AC2) 115VAC - Connect the neutral AC (white wire) to this terminal. NOTE: This is fused (F2) on the control.
(AC2) 230VAC - Connect either hot side.
P1-4 (+ ARMATURE) - Connects to the plus (+) Armature wire on the motor. 0-90VDC for 115VAC input or 0-180VDC for 230
VAC input. See “SPECIFICATIONS” for output rating.
CAUTION: ARMATURE CONNECTION MUST NOT BE SWITCHED OR BROKEN WHILE CONTROL IS ON
OR SERIOUS DAMAGE TO THE CONTROL MAY RESULT.
P1-5 (- ARMATURE) - Connects to minus (-) Armature wire (also considered circuit common) on the motor.
P1-6 (- FIELD) - Connect minus (-) Field wire of the Shunt Wound motor (not used on PM motors).
FIELD VOLTAGE TABLE
Model # VAC Input VDC Field
115 100
230 200
P1-7 (+ FIELD) - DO NOT use for Permanent Magnet motor. This supplies + Field voltage for a Shunt Wound motor. See chart
above for dual voltage Field Wound motors. This output is rated at 1 Amp for 530B series controls and 1.5 Amps for the
533B control. For motors with dual voltage field (ie. 50/100V or 100/200V), make sure the highest value is connected.
TERMINAL STRIP WIRING - P2
The 530B Series uses a 13 position barrier type terminal strip for control connections.
CAUTION: NONE OF THE P2 TERMINALS SHOULD BE EARTH GROUNDED!
P2-1 (OVER CURRENT OUT) - Can be used to signal that the control is in current limit. It can also signal other devices or alarms.
This is a low level logic signal which goes “high” when the current limit amplifier is in current limit. The logic of this control
is +12 volts, while the output at this terminal is approximately 1.5 volts through a 1000Ωresistor when in Current Limit.
P2-2 (AMP REF) - This is the common point of the logic. It is used as common with OVER CURRENT OUT (P2-1), +TACH (P2-
9), REV 1 (P2-7), REV 2 (P2-8), and WIPER (P2-4). NOTE: Never connect this terminal to earth ground !! Serious damage
and injury may result !! This terminal is electrically the same point as -ARM (P1-5).
P2-3 (SPEEDPOT LO) - Connects to the low side (orange wire) of the 5K Speedpot (normally the CCW end). This input is raised
and lowered by the MIN trimpot. Electronic speed input voltage (voltage follower) may be referenced to Speedpot LO if
the MIN trimpot adjustments are to be active. Otherwise, inputs may be referenced to AMP REF (P2-2), which will bypass
the MIN trimpot. INPUT MUST NOT BE GROUNDED !
CAUTION FOR VOLTAGE FOLLOWER APPLICATIONS:
THE INPUT CONNECTION TO THE SPEEDPOT MUST NOT BE GROUNDED !!
SERIOUS DAMAGE TO THE CONTROL MAY RESULT FROM A GROUNDED INPUT.
P2-4 (SPEEDPOT WIPER) - Connects to the wiper (red wire) of the Speedpot (center lead). Use this input for the plus (+) side
of voltage follower operation or tach follower. The minus (-) side connects to AMP REF (P2-2). INPUT MUST NOT BE
GREATER THAN +12V MAXIMUM AND MUST NOT BE GROUNDED !
P2-5 (SPEEDPOT HI) - Connects to high side (white wire) of the Speedpot (CW end). This is internal +12 volts. INPUT MUST
NOT BE GROUNDED !
P2-6 (SPARE) - This terminal is not connected to the control circuit. It can be used as a terminal for field modifications.

P2-7 (REV 1) - REV 1 and REV 2 are identical quick stop inputs. One of them must be held low (to AMP REF) before the control
will operate. The two are diode separated to form an “OR” gate. Since -ARM (P1-5) is also low in the system, these two
inputs can be wired to the motor side of a reversing switch or relay. During the period of switching, neither input will be
low, which will instantly return the set speed to zero and reset the acceleration ramp.
P2-8 (REV 2) - Identical to REV 1 (P2-7).
P2-9 (+TACH) - Connect +Tach from a DC tachometer for tachometer feedback. The minus (-) lead from the tachometer goes
to AMP REF (P2-2). Output voltage from the tachometer at full speed can range from 6 to 12 volts. The scale is corrected
using the JU3 jumper selectable setting of 3V/7V per 1000 RPM and the MAX speed trimpot. A 3 volt per 1000 RPM OR
7 volt per 1000 RPM tachometer should be used.
P2-10 (PILOT LIGHT) - Connecting point for on-off neon indicator lamp. The remaining lead will be connected to P2-11.
P2-11 (STOP) - Install one or more normally closed stop switches (in series) between STOP (P2-11) and COMMON (P2-12).
Not active on “C” version.
P2-12 (COMMON) - Mid point of Start-Stop switches. Not active on “C” version.
P2-13 (START) - Install one or more normally open start switches (in parallel) between START (P2-13) and COMMON (P2-12).
Not active on “C” version.

INITIAL START UP
1. Check to see that the 115/230 VAC selection switch is set for the desired input voltage.
2. Recheck all wiring. Accidental grounds, loose or pinched wires on armature or speed potentiometer wires may damage the
control when power is applied.
3. See “ADJUSTMENT PROCEDURE” and observe the WARNINGS pertaining to cover removal for adjustments.
4. Preset trimpots for your horsepower by using the “TRIMPOT CHART”. NOTE: Options may change the trimpot setting from
this chart. If your control has an option, be sure to carefully read the section in “OPTIONS” that pertains to your option.
5. Turn speed potentiometer to zero (fully CCW).
6. Turn power on and advance speedpot while observing motor.
7. If motor rotation is incorrect, turn power off at external disconnect and reverse the +ARM and -ARM connections.
8. If operation is satisfactory, no re-adjustments are needed.
9. If instability or surging is observed, or if maximum speed is higher than desired, proceed to “ADJUSTMENT PROCEDURE”.
10. For other problems, see section “IN CASE OF DIFFICULTY”.
7(Adjustment procedure continued)
WARNING:
WHEN MAKING AN ADJUSTMENT, ALWAYS USE A SCREWDRIVER WITH AN INSULATED SHAFT TO AVOID THE
SHORT CIRCUITING OF PC BOARD COMPONENTS. WHENEVER THE CONTROL COVER IS REMOVED, IT MUST BE
SUPPORTED TO AVOID ACCIDENTAL CONTACT BETWEEN CONTROL CHASSIS AND LIVE COVER COMPONENTS.
TRIMPOT ADJUSTMENT PROCEDURE
Four adjustments (MIN., MAX., I.R. COMP., and CUR. LIM.) are checked at the factory using a typical motor. Use the “TRIMPOT
CHART” to adjust the trimpots to the approximate setting for your horsepower. The other two adjustments (ACCEL and DECEL),
are the Acceleration and Deceleration adjustments and should be set for your particular application requirements. The “TRIMPOT
CHART” is approximate and is valid when using a speedpot or a 0 to 12VDC input signal to control the speed. Operation of the control
beyond ±10% of normal line voltage is not recommended and could result in readjustments. These settings are permanent; periodic
readjustment is normally not needed. (NOTE: Use only an ungrounded voltmeter).
MAX. Sets maximum motor speed when speedpot is at 100% CW rotation. Clockwise rotation increases maximum
motor speed.
1) Turn drive power OFF!
2) Connect a DC voltmeter; plus to +ARM and minus to -ARM.
3) Set meter voltage range for either 90 VDC or 180 VDC.
4) With no load on the motor, adjust the MAX trimpot to the rated armature voltage as seen on the meter.
NOTE: A tachometer or strobe may be used in place of a meter. Follow the above steps, but adjust the MAX trimpot
to the rated motor base speed, indicated by tach or strobe.
MIN. Sets minimum motor voltage when Speedpot is set at zero. Clockwise rotation of the MIN. trimpot will in-
crease the minimum motor voltage.
1) Set Speedpot to zero (fully CCW).
2) With no load on the motor, adjust the MIN trimpot clockwise until the motor starts to rotate.
3) Slowly back off the trimpot in the CCW direction until the motor stops.
NOTE: If motor rotation is desired at zero Speedpot setting, adjust the MIN trimpot clockwise until the desired
minimum speed is reached.
I.R. COMP. Provides a means of improving speed regulation in the armature feedback mode. If a change in motor speed
during a load change is of no concern, rotate this trimpot fully CCW.
1) Set speedpot at 50%.
2) Observe motor speed during a no load condition.
3) Apply a full load to the motor.
4) Adjust the I.R. COMP. trimpot clockwise (while the load is applied) until the no load motor speed is obtained.

CUR. LIM. Limits DC motor armature current (torque) to prevent damage to the motor or control. The current limit is
set for 125% of the rated motor current. Clockwise rotation of this trimpot increases the armature current
(or torque produced).
1) Turn drive power OFF!
2) Connect a DC Ammeter in series with the +ARM line (between +A on motor and +ARM on the control). Preset the
current limit trimpot CCW.
3) Turn power on and set speedpot to 50%.
4) Increase the motor load until the motor stalls (zero RPM).
5) Set CUR. LIM. trimpot by adjusting CW to 125% of the rated motor armature current (see “TRIMPOT CHART”).
ACCEL Allows adjustment of acceleration by user.
1) Clockwise trimpot rotation increases length of acceleration time needed for the control to reach full speed.
DECEL Allows adjustment of deceleration by user.
1) Clockwise trimpot rotation increases length of deceleration time needed for the control to reach zero speed.

NOTE: Jumper wires may be required on terminal strip P2 for the control to operate (refer to jumper chart below).
As explained in the “COMMONLY ASKED QUESTIONS” section, REV 1 (P2-7) and REV 2 (P2-8) are both stop inputs. One of
these inputs must be held low to AMP REF (P2-2) for the control to operate. Jumpering is necessary between AMP REF and REV
1 or REV 2 to satisfy the “OR” gate. An option board may be installed on the control satisfying the “OR” gate. This jumper (between
P2-2 and P2-7) is called JU2. For inhibiting with soft start and fast stop, the JU2 jumper may be replaced by a SPST switch.

Two pot operation is done usingtwo 10KΩ
speed potentiometers in parallel (both HI’s
to P2-5, both LO’s to P2-3). The WIPER is
switched usinga SPDT switch.
TWO SPEED OPERATION
A DPDT switch is used to inhibit the control and to connect the
DBR. Typical values for the DBR (dynamic brake resistor) are 5
for 115V, 10 for 230V (both 35Ωto 50Ω). Note that motor horse-
power, inertia, and cycle
time effect sizingof the
DBR.
NOTE: On -15A Option,
Decel must be fully CCW
to use with DBR.

The customer supplied SPST switch is connected in series
between the speedpot HI (P2-5) and the +TACH terminal
(P2-9). To inhibit, speedpot HI is closed to the +TACH term-
inal. To restart, the switch is returned to open. NOTE: The
control will stop and start fast.
INHIBIT (USED INDEPENDENTLY)
The customer supplied SPST switch is connected
in series between the speedpot HI terminal (P2-5)
and speedpot HI. To inhibit, the SPST switch
contacts are opened. To restart, the switch is
returned to the closed position. NOTE: The control
will soft stop and soft start through the acceleration
setting.
INHIBIT (USED WITH SPEEDPOT)
Improves speed regulation to –1/2% of base speed.

The -36M / -38M option automatically
“brakes” to zero speed before reversing.
The SPDT center-off switch is used to
select direction. When the direction is
reversed, relays K1, K2, and K3 connect
the dynamic brake resistor to the arma-
ture. The motor “brakes” and at zero
speed the relays reverse the armature
leads, causing the motor to rotate in the
opposite direction. When the switch is in
the center (STOP) position, the motor
armature is connected to the dynamic
brake resistor.
Notes: The start-stop switch is customer
provided on the “RC” version (see Hook-
up Diagrams for switch wiring). The “RE”
version requires a special cover that
must be ordered for field installed -36M
or -38M options. The Dynamic Brake
Resistor is mounted accordingly per
model (see above chart for placement).
VERY IMPORTANT:
DO NOT USE JU2 JUMPER WIRE with
this option. WHEN RETROFITTING,
JU2 JUMPER MUST BE REMOVED!!
