Connect the AC line power leads to terminals L1 and L2. ACE recommends the use of a double-pole, Use a 50K ohm, 1/4 W potenometer for speed control. Connect the counter-clockwise end of the
single throw master power switch. The switch should be rated at a minimum of 125 VAC and 200% of potenometer to S0, wiper to S2, and the clockwise end to S1. If the potenometer works
motor current. inversely of desired funconality, (i.e. to increase motor speed, you must turn the potenometer
counterclockwire), power off the drive and swap the S0 and S1 connecons. See the Operaon secon
Motor for alternave wiring setups.
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. Regenerave Brake
Short terminals S0 and T0 to regeneravely brake the motor to zero speed. The me it takes the motor
Field to come a stop is dependent on load inera, fricon, and the FWD TQ and REV TQ trim pot sengs.
Connect the field leads to terminals F1 and F2 for a 100 VDC field. Open terminals S0 and T0 to accelerate the motor to set speed.
Do not make any connecons to F1 and F2 if using a permanent magnet motor. Do not use the regenerave braking for emergency stopping.

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 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. Six 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.
Wiring
Use 18 - 24 AWG wire for logic wiring.
Use 14 - 16 AWG wire for AC line (L1, L2) and motor (A1, A2) 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. Refer to
the user’s manual for details on earth grounding shielded wires and filtering.
Fusing
ACE drives require an external line fuse for protecon. Use fast acng fuses rated for 125 VAC or
higher and 150% of the maximum armature current. Fuse the HOT leg of the AC line.

Safety Warnings
• 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 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 125 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.
• The field output is for shunt wound motors only. Do not make any connecons to F1 and F2 when
•using a permanent magnet motor.
• 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.

Calibration
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 MAX SPD trim pot unl the desired maximum speed is reached.
Forward Torque (FWD TQ) and Reverse Torque (REV TQ): The FWD TQ and REV TQ sengs determine
the maximum torque for accelerang and driving the motor in the forward and reverse direcon.
To calibrate the FWD TQ:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1. armature.
2. Set the FWD TQ 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 FWD TQ 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.
To calibrate the REV TQ:
1. Follow the steps for calibrang the foward torque using the REV TQ trim pot and with the
1. motor set to run in the reverse direcon.
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.
Deadband (DB): The deadband trim pot determines the me that will elapse between the applicaon
of current in one direcon before current is applied in the opposite direcon. The deadband trim pot
affects the resistance that a motor has to changes in sha posion at zero speed. It does this by
applying an AC voltage to the motor armature. Deadband is factory calibrated to approximately the
3 o’clock posion for 60 Hz AC line operaon. Recalibrate the deadband to the 9 o’clock posion for 50
Hz operaon. If you hear motor noise (humming), the deadband might be set too high. Turn the
deadband trim pot CCW unl the motor noise ceases.
