Page 10: Installation
Installation Mounting Warning Do not install, rewire, or remove this control with input power applied. Doing so may cause fire or serious injury. Make sure you have read and understood the Safety Warnings on page i before attempting installation. • Drive components are sensitive to electrostatic fields. Avoid contact with the circuit board directly. -
Page 11: Wiring
Installation Wiring Warning Do not install, remove, or rewire this equipment with power applied. Failure to heed this warning may result in fire, explosion, or serious injury. This drive is isolated from earth ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements. - Page 12 As a general rule, LEESON recommends shielding of all conductors. If it is not practical to shield power conductors, LEESON 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.

Page 13: Heat Sinking
Figure 3. Heatsink mounting Fuse / Circuit breaker protection All LEESON drives should be protected by a fuse or circuit breaker. Use a fast acting fuse or circuit breaker rated for approximately 200% of the maximum armature current and armature voltage. -
Page 14: Jumper 501 (Jp501)
Installation Jumper 501 (JP501) LEESON 17529X.00 series drives are shipped with pins 1 and 2 jumpered on JP501. This allows you to use 24 VDC motors with the 175290.00 and 175291.00, or 48 VDC motors with the 175292.00. To use lower voltage DC motors (12 VDC or 36 VDC, respectively) jumper pins 2 and 3 with the jumper provided. -
Page 15: Speed Adjust Potentiometer
Installation Speed adjust potentiometer Warning Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure. Grounding the input will cause damage to the drive. Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided (see Figure 5 on Page 10). Install the circular insulating disk between the panel and the 10K ohm speed adjust potentiometer. -

Page 17: Connections
Failure to heed this directive may result in fire or serious injury. LEESON strongly recommends the installation of a master power switch in the voltage input line, as shown in Figure 7, page 13. The switch contacts should be rated at a minimum of 200% of motor nameplate current and 150% of the input voltage. - Page 18 Installation Motor LEESON drives supply motor voltage from A1 and A2 terminals. It is assumed throughout this manual that, when A1 is positive with respect to A2, the motor will rotate clockwise (CW) while looking at the output shaft protruding from the front of the motor. If this is...

Page 20: Voltage Follower
Installation Voltage follower Instead of using a speed adjust potentiometer, the drive may be wired to follow a 0–10 VDC signal as shown in Figure 8. Connect the signal input (+) to S2. Connect the signal common (–) to S1. Make no connection to S3. -
Page 21: Operation
Operation Warning Dangerous voltages exist on the drive when it is powered, and up to 30 seconds after power is removed and the motor stops. BE ALERT. High voltages can cause serious or fatal injury. For your safety, use personal protective equipment (PPE) when operating this drive. -
Page 22: Startup And Shutdown
Operation Startup and shutdown To start the drive: 1. Turn the speed adjust potentiometer full counterclockwise (CCW), or set the voltage signal to zero. 2. Apply DC voltage input. 3. Slowly advance the speed adjust potentiometer clockwise (CW), or increase the voltage signal. The motor slowly accelerates as the potentiometer is turned CW or the voltage signal is increased. -
Page 23: Starting And Stopping Methods
Removing DC line power is the only acceptable method for emergency stopping. For this reason, LEESON strongly recommends installing an emergency stop switch (see figure 7, page 13). Frequent decelerating to minimum speed produces high torque. -
Page 24: Figure 9. Run/Decelerate To Minimum Speed Switch
Operation Decelerating to minimum speed A single pole, single throw switch may be used to decelerate a motor to minimum speed (see Figure 9). Close the switch between S1 and S2 to decelerate the motor from set speed to minimum speed. -
Page 25: Inhibit Terminals
Operation Inhibit terminals Short the INHIBIT terminals to coast the motor to zero speed (see Figure 10 for INHIBIT terminal location). Reopen the INHIBIT terminals to accelerate the motor to set speed. Twist inhibit wires and separate them from other power-carrying wires or sources of electrical noise. -

Page 27: Calibration
Calibration Warning Dangerous voltages exist on the drive when it is powered, and up to 30 seconds after power is removed and the motor stops. When possible, disconnect the voltage input from the drive before adjusting the trimpots. If the trimpots must be adjusted with power applied, use insulated tools and the appropriate personal protection equipment. -
Page 28: Minimum Speed (Min Spd)
Calibration MINIMUM SPEED (MIN SPD) The MIN SPD setting determines the motor speed when the speed adjust potentiometer is turned full CCW. It is factory set for zero speed. To calibrate MIN SPD: 1. Set the MAX SPD trimpot to full CW. 2. -
Page 29: Acceleration (Accel)
Calibration ACCELERATION (ACCEL) The ACCEL setting determines the time the motor takes to accelerate to a higher speed. See Specifications on page 1 for approximate acceleration times. The ACCEL setting is factory set to its minimum value (full CCW). To calibrate ACCEL: 1. -
Page 30: Ir Compensation (Ir Comp)
Calibration IR COMPENSATION (IR COMP) The IR COMP setting determines the degree to which motor speed is held constant as the motor load changes. It is factory set for optimum motor regulation. Use the following procedure to recalibrate the IR COMP setting : 1. -
Page 31: Current Limit (Cur Limit)
CURRENT LIMIT should be set to 120% of motor nameplate current rating. Continuous operation beyond this setting may damage the motor. If you intend to operate beyond the rating, contact your LEESON representative. The CURRENT LIMIT setting determines the maximum armature current output of the drive. -

Page 35: Independent Adjustable Speeds
Application Notes Independent adjustable speeds Replace the speed adjust potentiometer with a single pole, multi- position switch, and two or more potentiometers in parallel, with a total parallel resistance of 10K ohms. Figure 16 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations. -
Page 36: Run/Jog Switch
Application Notes RUN/JOG switch Using a RUN/JOG switch is recommended in applications where quick stopping is not needed and frequent jogging is required. Use a single pole, two position switch for the RUN/JOG switch, and a normally closed, momentary operated pushbutton for the JOG pushbutton (see Figure 17). -
Page 37: Reversing
Application Notes Reversing Warning Do not operate the control outside the recommended input ±10%. Relays may be used in place of a switch, but a neutral position must be provided to prevent plug reversing (see Figure 18, page 32). DO NOT CHANGE DIRECTIONS WHILE THE MOTOR IS STILL RUNNING. -
