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 potentiometer 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       potentiometer to S0, wiper to S2, and the clockwise end to S1. If the potentiometer works

     inversely of desired functionality, (i.e. to increase motor speed, you must turn the potentiometer

for alternative wiring setups.

Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired 

     

direction, power down the drive and reverse these connections. 

 

 

     

Regenerative Brake

 

 

 

 

 

 

 

     Short terminals S0 and T0 to regeneratively brake the motor to zero speed. The time it takes the motor

Field

 

 

 

 

 

 

 

     to come a stop is dependent on load inertia, friction, and the FWD TQ and REV TQ trim pot settings.

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 connections to F1 and F2 if using a permanent magnet motor. 

 

     Do not use the regenerative braking for emergency stopping.

Installation 

Mounting

•  Drive components are sensitive to electrostatic 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 calibration trim pots.

•  Mount the drive away from heat sources.  Operate the drive within the specified ambient operating

•  

temperature range.  

•  Prevent loose connections by avoiding excessive vibration of the drive.

•  Mount the drive with its board in either a horizontal or vertical 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 practical to shield power

conductors, ACE recommends shielding all logic-level leads. If shielding of logic-level leads is not

practical, 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 protection. Use fast acting 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 National

  Electrical Code and all other applicable electrical and safety codes, including the provisions of the

  Occupational Safety and Health Act (OSHA), when installing equipment.

•  

Circuit potentials 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 adjusting the calibration trim pots. Use approved personal protection 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

  protection, thermal protection, and enclosure. Follow sound maintenance procedures.

• 

 ACE strongly recommends the installation 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

  regenerative braking, decelerating to minimum speed, or coasting to a stop for emergency stopping.

  They may not stop a drive that is malfunctioning. Removing AC line power is the only acceptable

  method for emergency stopping.

•  Line starting and stopping (applying and removing AC line voltage) is recommended for infrequent

  starting and stopping of a drive only. Regenerative braking, decelerating to minimum speed, or

  coasting to a stop is recommended for frequent starts and stops. Frequent starting 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 connections to F1 and F2 when

  using a permanent magnet motor.

•  Under no circumstances should power and logic level wires be bundled together.

•  Be sure potentiometer tabs do no make contact with the potentiometer’s body. Grounding the

  input will cause damage to the drive.
