WARNING: The circuits connected to terminals COM, AX1, AX2, SIG, and +V are NOT isolated from
power circuits by Protecve Separaon in accordance with UL 61800-5-1. Protecve separaon to
protect these circuits against direct contact is to be supplied by the end user.
• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a
• qualified electrical technician install, adjust and service this equipment. Follow the Naonal
•Electrical Code and all other applicable electrical and safety codes, including the provisions of the
•Occupaonal Safety and Health Act (OSHA), when installing equipment.
• Circuit potenals are at 115 or 230 VAC above earth ground. Avoid direct contact with the printed
• circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use a non-
• metallic screwdriver for adjusng the calibraon trim pots. Use approved personal protecon
•equipment and insulated tools if working on this drive with power applied.
• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding, over-current
•protecon, thermal protecon, and enclosure. Follow sound maintenance procedures.
• ACE strongly recommends the installaon of a master power switch in the line voltage input. The
•switch contacts should be rated for 250 VAC and 200% of motor nameplate current.
• Removing AC line power is the only acceptable method for emergency stopping. Do not use
•regenerave braking, decelerang to minimum speed, or coasng to a stop for emergency stopping.
•They may not stop a drive that is malfunconing. Removing AC line power is the only acceptable
•method for emergency stopping.
• Line starng and stopping (applying and removing AC line voltage) is recommended for infrequent
•starng and stopping of a drive only. Regenerave braking, decelerang to minimum speed, or
•coasng to a stop is recommended for frequent starts and stops. Frequent starng and stopping can
•produce high torque. This may cause damage to motors.
• Do not disconnect any of the motor leads from the drive unless power is removed or the drive is
•disabled. Opening any one lead while the drive is running may destroy the drive.
• Under no circumstances should power and logic level wires be bundled together.
• Be sure potenometer tabs do no make contact with the potenometer’s body. Grounding the
•input will cause damage to the drive.
• This product does not contain speed sensive overload protecon, thermal memory retenon, or
•provisions to receive and act upon signals from remote devices for over temperature protecon. If
•motor protecon is needed in the end-use product, it needs to be provided by addional equipment
•in accordance with NEC standards.
• This product does not have internal solid state motor overload protecon. It does not contain speed-
•sensive overload protecon, thermal memory retenon, or provisions to receive and act upon
•signals from remote devices for over temperature protecon. If motor protecon is needed in the
•end-use product, it needs to be provided by addional equipment in accordance with NEC standards.

SCCR (Short Circuit Current Rang): MGB400 series drives are suitable for use on a circuit capable of
delivering not more than 5,000 RMS symmetrical amperes, 115/230 volts maximum.
Branch Circuit Protecon: Class J, Class CC, or Class T fuses are to be rated with a minimum of 230 VAC
and a maximum current rang of 40 amps. Circuit breakers are to be rated at a minimum of 230 VAC
with a maximum current rang of 30 amps.
Mounng
• Install the drive in a Polluon Degree 2 environment only.
• Drive components are sensive to electrostac discharge. Avoid direct contact with the circuit
• board. Hold the drive by the chassis only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and calibraon trim pots.
• Mount the drive away from heat sources. Operate the drive within the specified ambient operang
• temperature range.
• Prevent loose connecons by avoiding excessive vibraon of the drive.
• Mount the drive with its board in either a horizontal or vercal plane. Eight 0.19” (5 mm) wide slots
• in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the
• chassis to the subplate.
• The chassis should be earth grounded. Connect the ground to the green screw on the chassis.
Heat Sinking: The MGB400-11 requires an addional heat sink when the connuous armature current
is above 8 amps. Use heat sink kit part number 223-0159. Use a thermally conducve heat sink
compound (such as Dow Corning 340® Heat Sink Compound) between the chassis and the heat sink
surface for opmal heat transfer.
Wiring: 60°C wire was used in UL evaluaon of the power wiring terminals (L1, L2, A1, A2). Use
18 - 24 AWG wire for logic wiring. Use 14 AWG wire for AC line (L1, L2) and motor (A1, A2) wiring.
Shielding Guidelines: As a general rule, it is recommended to shield all conductors. If it is not praccal
to shield power conductors, it is recommended to shield all logic-level leads. If shielding of logic-level
leads is not praccal, the user should twist all logic leads with themselves to minimize induced noise.
Refer to the user’s manual for details on earth grounding shielded wires and filtering.

Speed Potenometer
Use a 10K ohm, 1/4 W potenometer for speed control. Connect the counter-clockwise end of the
potenometer to COM, wiper to SIG, and the clockwise end to +V. If the potenometer works
inveresly of desired funconality, (i.e. to increase motor speed, you must turn the potenometer
counterclockwire), power off the drive and swap the COM and +V connecons. To use an isolated
analog signal instead, connect the signal negave (-) to COM and the signal reference (+) to SIG.
Direcon (AX1)
Short terminals AX1 and COM to change the direcon of The motor. If no direcon switch is desired,
leave this connecon open.
Inhibit / Enable (AX2)
Short terminals AX2 and COM to stop the motor. Refer to jumpers 2 and 3 in the Startup secon to
determine if the switch is normally open or normally closed, and if the motor will regeneravely brake
or coast to a stop. Do not use the inhibit or enable for emergency stopping.
Warning: The circuits connected to terminals AX1, AX2, COM, SIG, and +V are not isolated from the
power circuits by Protecve Separaon in accordance with UL 61800-5-1. Protecve separaon to
protect these circuits against direct contact is to be supplied by the end user.
Line Input
Connect the AC line power leads to terminals L1 and L2, or to a double-pole, single-throw master
power switch (recommended). The switch should be rated at a minimum of 250 VAC and 200% of
motor current.
Motor
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired
direcon, power down the drive and reverse these connecons.

JUMPERS
Startup
STATUS
LED
LIMIT
LED
STATUS LED (Green)
Solid: AC line voltage is applied to the drive and the drive is enabled to run.
1 Flash: The drive is disabled or inhibited.
2 Flashes: Either Jumper 1, 2, or 5 was changed during operaon. To change these sengs, the drive
must either be disabled or powered off.
LIMIT LED (Red)
Solid: The drive is in current limit. This means the motor is asking for more current (torque) than the
drive is set to allow out. Either reduce the amount of torque required by the motor or raise the current
limit output of the drive using the Torque (CL) trim pot.
LEDs
Offset (OFFST): The OFFST seng determines the minimum motor speed when the speed adjust
potenometer or analog voltage signal is set for minimum speed. To calibrate the OFFST:
1. Set the OFFST trim pot full CCW.
2. Set the speed adjust potenometer or analog voltage signal for minimum speed.
3. Adjust OFFST trim pot unl the desired minimum speed is reached.
Maximum Speed (MX SPD): The MX SPD seng determines the maximum motor speed when the
speed adjust potenometer is set for maximum speed. To calibrate the MX SPD:
1. Set the MX SPD trim pot full CCW.
2. Set the speed adjust potenometer for maximum speed.
3. Adjust MX SPD trim pot unl the desired maximum speed is reached.
Torque (CL): The CL seng determines the maximum torque for accelerang, driving, and decelerang
the motor in both the forward and reverse direcons.
To calibrate CL:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1. armature.
2. Set the CL trim pot to minimum (full CCW).
3. Set the speed adjust potenometer to maximum forward speed (full CW).
4. Carefully lock the motor armature. Be sure that the motor is firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the CL trim pot CW unl the armature current is 150% of motor rated
6. armature current.
7. Turn the speed adjust potenometer to minimum speed (full CCW).
8. Remove line power.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is no longer needed.
IR Compensaon (IR): The IR seng determines the degree to which motor speed is held constant as
the motor load changes. To calibrate the IR:
1. Set the IR trim pot full CCW.
2. Increase the speed adjust potenometer unl the motor runs at midspeed without load. A
2. handheld tachometer may be used to measure motor speed.
3. Load the motor armature to its full load armature current rang. The motor should slow down.
4. While keeping the load on the motor, rotate the IR trim pot unl the motor runs at the
4. speed measured in step 2. If the motor oscillates (overcompensaon), the IR trim pot
4. may be set too high (CW). Turn the IR trim pot CCW to stabilize the motor.
5. Unload the motor.
