Installation
Mounng
• Drive components are sensive to electrostac discharge. Avoid direct contact with the circuit
• board. Hold the drive by the chassis or heat sink 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. Use a star washer beneath the head of at least one of the
• mounng screws to penetrate the anodized chassis surface and to reach bare metal.
Heat Sinking
The PWM400-10 requires an addional heat sink when the connuous armature current is above 5
amps. Use ACE heat sink kit part number HSK-0001. 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
Use 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for AC line and motor wiring.
Shielding Guidelines
As a general rule, ACE recommends shielding of all conductors. If it is not praccal to shield power
conductors, ACE recommends shielding 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. It may be
necessary to earth ground the shielded cable. If noise is produced by devices other than the drive,
ground the shield at the drive end. If noise is generated by the drive, ground the shield at the end
away from the drive. Do not ground both ends of the shield.
Fusing
ACE drives require an external line fuse for protecon. Use fast acng fuses rated for 250 VAC or
higher and 150% of the maximum armature current. Fuse the HOT leg of the AC line when using 115
VAC and both lines when using 230 VAC.

Inhibit
Terminals
Line Input
Connect the AC line power leads to terminals L1 and L2. ACE recommends the use of a double-pole,
single-throw master power switch. 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.
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 S1, the wiper to S2, and the clockwise end to S3. If the potenometer works inversely of
desired funconality, (i.e. to increase motor speed, you must turn the potenometer counterclockwise),
power off the drive and swap the S1 and S3 connecons.
Inhibit
Short the INHIBIT terminals to coast the motor to zero speed. Open the INHIBIT terminals to
accelerate the motor to set speed. Twist inhibit wires and seperate them from power-carrying wires or
sources of electrical noise. Use shielded cable if the inhibit wires are longer than 18 inches (46 cm). If
shielded cable is used, ground only one end of the shield to earth ground. Do not ground both ends of
the shield. Do not use the inhibit for emergency stopping.
ACE offers two accessory plug harnesses for connecng to the inhibit terminals; part number KTW-0001
[18 in (46 cm) leads] and part number KTW-0002 [36 in (91 cm) leads].

Calibration
Minimum Speed (MIN SPD): The MIN SPD seng determines the minimum motor speed when the
speed adjust potenometer is set for minimum speed. It is factory set for zero speed. To calibrate the
MIN SPD:
1. Set the MIN SPD trim pot full CCW.
2. Set the speed adjust potenometer for minimum speed.
3. Adjust the MIN SPD trim pot unl the desired minimum speed is reached or is just at the
3. threshold of rotaon.
Maximum Speed (MAX SPD): The MAX SPD seng determines the maximum motor speed when the
speed adjust potenometer is set for maximum speed. To calibrate the MAX SPD:
1. Set the MAX SPD trim pot full CCW.
2. Set the speed adjust potenometer for maximum speed.
3. Adjust the MAX SPD trim pot unl the desired maximum speed is reached.
Check the MIN SPD and MAX SPD adjustments aer recalibrang to verify that the motor runs at the
desired minimum and maximum speed.
Torque (CURRENT LIMIT): The CURRENT LIMIT seng determines the maximum torque for
accelerang and driving the motor. To calibrate the CURRENT LIMIT:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1. armature.
2. Set the CURRENT LIMIT trim pot to minimum (full CCW).
3. Set the speed adjust potenometer to maximum 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 CURRENT LIMIT trim pot CW unl the armature current is 150% of motor
6. rated armature current. Connuous operaon beyond this rang may damage the motor.
7. Turn the speed adjust potenometer 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 COMP): The IR COMP seng determines the degree to which motor speed is
held constant as the motor load changes. To calibrate the IR COMP:
1. Set the IR COMP 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 COMP trim pot unl the motor runs at the
4. speed measured in step 2. If the motor oscillates (overcompensaon), the IR COMP trim pot
4. may be set too high (CW). Turn the IR COMP trim pot CCW to stabilize the motor.
5. Unload the motor.
Acceleraon (ACCEL): The ACCEL seng determines the me the motor takes to ramp to a higher
speed. ACCEL is factory set for the shortest acceleraon me (full CCW). To calibrate the ACCEL:
1. Set the speed adjust potenometer for minimum speed.
2. Set the speed adjust potenometer for maximum speed. Measure the me is takes the motor
2. to go from minimum speed to maximum speed.
3. If the me measured in step 2 is not the desired acceleraon me, turn the ACCEL trim pot
3. CW for a longer acceleraon me, or CCW for a shorter acceleraon me. Repeat steps 1
3. through 3 unl the acceleraon me is correct.
Deceleraon (DECEL): The DECEL seng determines the me the motor takes to ramp to a lower
speed. DECEL is factory set for the shortest deceleraon me (full CCW). To calibrate the DECEL:
1. Set the speed adjust potenometer for maximum speed.
2. Set the speed adjust potenometer for minimum speed. Measure the me is takes the motor
2. to go from maximum speed to minimum speed.
3. If the me measured in step 2 is not the desired deceleraon me, turn the DECEL trim pot
3. CW for a longer deceleraon me, or CCW for a shorter deceleraon me. Repeat steps 1
3. through 3 unl the deceleraon me is correct.

Reversing with a Dynamic Brake
A dynamic brake may be used when reversing the motor direcon. Use a three pole, three posion
switch rated for at least the armature voltage rang and 150% of the armature current rang. For the
dynamic brake resistor, use a 40 wa minimum, high power, wirewound resistor. Sizing the dynamic
brake resistor depends on load inera, motor voltage, and braking me. Use a lower-value,
higher-waage dynamic brake resistor to stop a motor more rapidly. Recommended values are 15
ohms for a 130 VDC motor and 30 ohms for 240 VDC motor. The motor must come to a complete stop
before changing direcons.

Decelerate to Minimum Speed
The switch shown below may be used to decelerate a motor to a minimum speed. Closing the switch
between S1 and S2 decelerates the motor from set speed to a minimum speed determined by the MIN
SPD trim pot seng. If the MIN SPD trim pot is set full CCW, the motor decelerates to zero speed when
the switch between S1 and S2 is closed. The DECEL trim pot seng determines the rate at which the
drive decelerates. By opening the switch, the motor accelerates to set speed at a rate determined by
the ACCEL trim pot seng.
Decelerate to Zero Speed (Coast)
See INHIBIT in the CONNECTIONS secon on page 1 for a descripon of wiring and connecon
locaons.
Decelerate to Zero Speed (Dynamic Brake)
Dynamic braking may be used to rapidly stop a motor. For the RUN/BRAKE switch, use a two pole,
two posion switch rated for at least the armature voltage rang and 150% of the armature current
rang. For the dynamic brake resistor, use a 40 wa minimum, high power, wirewound resistor. Sizing
the dynamic brake resistor depends on load inera, motor voltage, and braking me. Use a lower-value,
higher-waage dynamic brake resistor to stop a motor more rapidly. Recommended values are 15
ohms for a 130 VDC motor and 30 ohms for 240 VDC motor.
