    SPEEDMASTER™ OPERATION MANUAL Calibration Warning Dangerous voltages exist on the drive when it is powered. 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 19: Calibration Procedure

    Calibration SPEEDMASTER™ OPERATION MANUAL Calibration procedure Calibrate the drive using the following procedure: Set the MIN SPD, IR COMP, ACCEL and DECEL trimpots to zero (full CCW). Set the TORQUE trimpot to maximum (full CW). Set the MAX SPD trimpot to midrange (approximate 12 o’clock position).

  • Page 20: Maximum Speed (Max Spd)

    SPEEDMASTER™ OPERATION MANUAL Calibration MAXIMUM SPEED (MAX SPD) The MAX SPD setting determines the motor speed when the speed adjust potentiometer is turned full CW or reference signal is at its maximum. It is factory set for maximum rated speed. To calibrate, set the MAX SPD trimpot full CCW.

  • Page 21: Torque Limit (Torque)

    Although TORQUE is set to 150% of drive nameplate current rating, continuous operating beyond that rating may damage the motor. If you intend to operate beyond the rating, contact your LEESON representative for assistance. The TORQUE setting determines the maximum torque for accelerating and driving the motor.

  • Page 22: Acceleration (Accel)

    SPEEDMASTER™ OPERATION MANUAL Calibration Remove power from the drive. Remove the lock from the motor shaft. 10. Remove the ammeter in series with the motor armature. ACCELERATION (ACCEL) The ACCEL setting determines the time the motor takes to ramp to a higher speed. See Specifications on page 1 for approximate acceleration times.

  • Page 24: Operation

    SPEEDMASTER™ OPERATION MANUAL Operation Warning Change voltage switch settings only when the drive is disconnected from AC line voltage. Make sure both switches are set to their correct position. If the switches are improperly set to a lower voltage position, the motor will not run at full voltage.

  • Page 25: Startup

    Operation SPEEDMASTER™ OPERATION MANUAL Startup Warning If the motor or drive does not perform as described in this section, disconnect the AC line voltage immediately. Refer to Troubleshooting, page 34, for further assistance. 174102 1. Set the speed adjust potentiometer (SPEED dial) to “0”, or full CCW.
  • Page 26 SPEEDMASTER™ OPERATION MANUAL Operation 174103 Manual Operation 1. Set the Signal/Manual Switch located on the enclosure to the MANUAL position. 2. Set the speed adjust dial to “0” (full CCW). 3. Apply AC line voltage 4. Set the POWER switch to the ON position 5.
  • Page 27 SPEEDMASTER™ OPERATION MANUAL 174107 Warning Do not change the FORWARD / OFF / REVERSE switch while the motor is running. The motor must come to a complete stop before reversing. Changing motor direction before allowing the motor to completely stop will cause excessively high current to flow in the armature circuit, and may damage the drive and/or motor.

  • Page 28: Application Notes

    Removing the connection between the inhibit pins allows the motor to accelerate to the speed set by the speed adjust potentiometer. LEESON offers an accessory plug harness for connecting to the INHIBIT terminals: part number 900282.01 [inhibit plug with 18 inches (46 cm) leads].

    Application Notes COAST TO MIN SPEED SO501 2-PIN HEADER Use LEESON accessory plug harness (part number: 900282.01) to mate with 2-pin header (SO501) on control board. Figure 7. Inhibit Plug with Run/Coast to Minimum Speed...

  • Page 30: Decelerating To Minimum Speed

    Application Notes Decelerating to minimum speed The switch shown in Figure 8 may be used to decelerate a motor to minimum speed. Closing the switch between S1 and S2 decelerates the motor from set speed to minimum speed determined by the MIN SPD trimpot setting. If the MIN SPD trimpot is set full CCW, the motor decelerates to zero speed when the switch between S1 and S2 is closed.

  • Page 31: Dynamic Braking

    Application Notes Dynamic Braking Warning Wait for the motor to completely stop before switching it back to the RUN position. This will prevent high armature currents from damaging the motor or drive. Dynamic braking may be used to rapidly stop a motor (Figure 9, page 25).

    Application Notes Multiple Fixed Speeds Replace the speed adjust potentiometer with series resistors with a total series resistance of 10K ohms (Figure 10). Add a single-pole, multi-position switch with the correct number of positions for the desired number of fixed speeds. TOTAL SERIES RESISTANCE 10K OHMS...

    Application Notes Adjustable speeds using potentiometers in series Replace the speed adjust potentiometer with a single-pole, multi- position switch, and two or more potentiometers in series, with a total series resistance of 10K ohms. Figure 11 shows a connection for fixed high and low speed adjust potentiometers. SPEED HIGH SPEED...

  • 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 12 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations.

  • Page 37: Run/Jog Option #2

    Application Notes RUN/JOG option #2 In the second wiring option, connect the RUN/JOG switch and the JOG pushbutton as shown in Figure 14. When the RUN/JOG switch is set to JOG, the motor decelerates to minimum speed (minimum speed is determined by the MIN SPD trimpot setting).

  • Page 38: Leader-Follower Application

    Application Notes Leader-follower application In this application, use a 174335 Process Control Module (PCM) to monitor the speed of the leader motor (Figure 15). The PCM isolates the leader motor from the follower drive, and outputs a voltage proportional to the leader motor armature voltage. The follower drive uses this voltage reference to set the speed of the follower motor.

  • Page 39: Single Speed Potentiometer Control Of Multiple Drives

    Application Notes Single speed potentiometer control of multiple drives Multiple drives can be controlled with a single speed adjust potentiometer using a 174335 Process Control Module (PCM) at the input of each drive to provide isolation (Figure 16). Optional ratio potentiometers can be used to scale the PCM output voltage, allowing independent control of each drive.
