Specifications 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 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 techniques,
• over-current protecon, thermal protecon, and enclosure. Follow sound maintenance procedures.
• Removing AC line power is the only acceptable method for emergency stopping. Do not use
• dynamic 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. Dynamic 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.
• Change voltage switch sengs only when the drive is disconnected from AC line voltage. Make sure
• both switches are set to their correct posion. If the switches are improperly set to a lower voltage
• posion, the motor will not run at full voltage and may cause damage to the transformer. If the
•switches are improperly set to a higher voltage, the motor will overspeed, which may cause motor
• damage, or result in bodily injury or loss of life.
• Do not change the FORWARD/REVERSE switch while the motor is running. The motor must come
• to a complete stop before reversing. Changing motor direcon before allowing the motor to
•completely stop will damage the drive and/or motor.

Installation
Mounng
NEMA 1 cased drives come with two 0.88 inch (22 mm) conduit holes at the boom of the case. The
drives may be vercally wall mounted or horizontally bench mounted using the three keyholes on the
back of the case.
1. For access to the keyholes and the terminal strip, remove the two screws from the front of the case
1. by turning them counterclockwise. Grasp the front cover and pull it straight out.
2. Install the monng screws in the three keyholes.
3. Set the POWER switch to the OFF posion before applying the AC line voltage.
4. Install conduit hardware through the conduit holes at the boom of the case. Connect external
3. wiring to the terminal block.
5. Reinstall the front cover. Avoid pinching any wires between the front cover and the case.
6. Reinstall the two screws on the front cover. Turn the screws clockwise to ghten.
Heat Sinking
The LGD430-10 requires an addional heat sink when the connuous armature current is above 5
amps. Use ACE heat sink kit part number HSK-0002. Use a thermally conducve heat sink compound
(such as Dow Corning 340® Heat Sink Compound) between the back of the case and the heat sink
surface for opmal heat transfer.
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
LGD430 series drives provide fusing for the AC line (1, 3). Fuses are fast acng fuses. LGD430-1.5
models contain fuses rated for 3A at 250 VAC. LGD430-10 models contain fuses rated for 15A at
250 VAC.
Connections
POWER
Line Input
Connect the AC line power leads to terminals L1 and L2, or to a double-throw, single-pole 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 spins in the reverse of desired rotaon,
simply power down the drive and reverse these connecons.
LOGIC
Speed Potenometer
S1, the wiper
to S2, and the supply to S3. If the potenometer works inveresly 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 minimum 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.
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].
Line Input
Connect the AC line power leads to terminals 1 and 2 if using 115 VAC line power or to terminals 1 and 3
if using 230 VAC line power.
Motor
Connect the DC armature leads to terminals 4 and 5. If the motor does not spin in the desired direcon,
power down the drive and reverse these connecons.
Speed Potenometer (Pre-wired)
LGD430 series drives are pre-installed with a 10K ohm, 1/4 W potenometer for speed control.
Run/Stop Switch (Pre-wired)
LGD430 series drives are pre-installed with a Run/Stop switch. When set to Stop, this switch will inhibit
the drive, disconnect the motor armature, and connect a dynamic braking resistor across the motor. The
dynamic braking resistor allows the motor to stop quicker than if allowed to naturally coast to a stop.
Forward/Reverse Switch (Pre-wired)
LGD430 series drives are pre-installed with a Forward/Reverse switch. This switch swaps the motor
armature wires to change motor rotaon direcon. To use the Forward/Reverse Switch, first set the
Run/Stop switch to Stop. When the motor has come to a complete stop, toggle the direcon switch
and then set the Run/Stop switch to Run. Do not change the Forward/Reverse switch while the motor
is running.

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 (TORQUE): The TORQUE seng determines the maximum torque for accelerang and driving
the motor. To calibrate the TORQUE:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1. armature.
2. Set the TORQUE 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 TORQUE trim pot CW unl the armature current is 150% of motor rated
6. 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.
