(OPTIONAL)
Line Input Speed Potenometer
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 potenometer for speed control. Connect the counter-clockwise end of the
single throw master power switch. The switch should be rated at a minimum of 250 VAC and 200% of potenometer to S0, wiper to S2, and the clockwise end to S1. If the potenometer works
motor current. inversely of desired funconality, (i.e. to increase motor speed, you must turn the potenometer
counterclockwire), power off the drive and swap the S0 and S1 connecons. See the Operaon secon
Motor for alternave wiring setups.
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired
direcon, power down the drive and reverse these connecons. Regenerave Brake
Short terminals S0 and RB to regeneravely brake the motor to zero speed. The me it takes the motor
to come a stop is dependent on load inera, fricon, and the FWD TQ and REV TQ trim pot sengs.
Open terminals S0 and RB to accelerate the motor to set speed.
Do not use the regenerave braking for emergency stopping.

Installation
Mounng
• Drive components are sensive to electrostac 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 calibraon trim pots.
• Mount the drive away from heat sources. Operate the drive within the specified ambient operang
• temperature range.
• Prevent loose connecons by avoiding excessive vibraon of the drive.
• Mount the drive with its board in either a horizontal or vercal 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.
• The chassis should be earth grounded. Use a star washer beneath the head of at least one of the
• mounng screws to penetrate the anodized chassis surface and to reach bare metal.
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 praccal to shield power
conductors, ACE recommends shielding all logic-level leads. If shielding of logic-level leads is not
praccal, 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 protecon. Use fast acng 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.

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 Naonal
•Electrical Code and all other applicable electrical and safety codes, including the provisions of the
• Occupaonal Safety and Health Act (OSHA), when installing equipment.
• Circuit potenals 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 adjusng the calibraon trim pots. Use approved personal protecon 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
• protecon, thermal protecon, and enclosure. Follow sound maintenance procedures.
• ACE strongly recommends the installaon 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
• regenerave braking, decelerang to minimum speed, or coasng to a stop for emergency stopping.
• They may not stop a drive that is malfunconing. Removing AC line power is the only acceptable
•method for emergency stopping.
• Line starng and stopping (applying and removing AC line voltage) is recommended for infrequent
• starng and stopping of a drive only. Regenerave braking, decelerang to minimum speed, or
• coasng to a stop is recommended for frequent starts and stops. Frequent starng 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 potenometer tabs do no make contact with the potenometer’s body. Grounding the
•input will cause damage to the drive.

Calibration
Maximum Speed (MAX SPD): The MAX SPD seng determines the maximum motor speed when the
speed adjust potenometer is set for maximum speed. To calibrate the MAX SPD:
1. Set the MAX SPD trim pot full CCW.
2. Set the speed adjust potenometer for maximum speed.
3. Adjust MAX SPD trim pot unl the desired maximum speed is reached.
Forward Torque (FWD TQ) and Reverse Torque (REV TQ): The FWD TQ and REV TQ sengs determine
the maximum torque for accelerang and driving the motor in the forward and reverse direcon.
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 potenometer 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 unl the armature current is 150% of motor rated
6. armature current.
7. Turn the speed adjust potenometer 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 calibrang the foward torque using the REV TQ trim pot and with the
1. motor set to run in the reverse direcon.
IR Compensaon (IR COMP): The IR COMP seng 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 potenometer unl 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 rang. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP trim pot unl the motor runs at the
4. speed measured in step 2. If the motor oscillates (overcompensaon), 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 applicaon
of current in one direcon before current is applied in the opposite direcon. The deadband trim pot
affects the resistance that a motor has to changes in sha posion 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 posion for 60 Hz AC line operaon. Recalibrate the deadband to the 9 o’clock posion for 50
Hz operaon. If you hear motor noise (humming), the deadband might be set too high. Turn the
deadband trim pot CCW unl the motor noise ceases.
