    Operation Inhibit terminals Short the INHIBIT terminals to coast the motor to minimum speed (see Figure 15 for INHIBIT terminal location). Open the INHIBIT terminals to accelerate the motor to set speed. Twist inhibit wires and separate them from power-carrying wires or sources of electrical noise.

  • Page 205: Decelerating To Minimum Speed

    Operation Decelerating to minimum speed The switch shown in Figure 16 may be used to decelerate a motor to a minimum speed. Closing the switch between S1 and S2 decelerates the motor from set speed to a 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 206: Dynamic Braking

    Operation Dynamic braking Warning For frequent starts and stops, short the inhibit terminals, decelerate to a minimum speed, or apply a dynamic brake to the motor. Do not use any of these methods for emergency stopping. They may not stop a drive that is malfunctioning. Removing AC line power (both L1 and L2) is the only acceptable method for emergency stopping.
  • Page 207 Operation Table 4. Minimum Recommended Dynamic Brake Resistor Values Motor Armature Dynamic Brake Voltage Resistor Value 90 VDC 15 ohms 180 VDC 30 ohms For motors rated horsepower and lower, a brake resistor is not necessary since the armature resistance is high enough to stop the motor without demagnetization.

  • Page 208: Calibration

    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 209: Minimum Speed (Min Spd)

    Calibration MINIMUM SPEED (MIN SPD) The MIN SPD trimpot establishes the motor speed obtained in response to the minimum input signal. It is factory set for zero speed. To calibrate the MIN SPD pot, apply the minimum signal. Adjust the MIN SPD trimpot until the motor runs at the desired speed or is just at the threshold of rotation.
  • Page 210 Calibration TORQUE Warning TORQUE should be set to 150% of motor nameplate current rating. Continuous operation beyond this rating may damage the motor. If you intend to operate beyond the rating, contact your Minarik representative for assistance. The TORQUE setting determines the maximum torque for accelerating and driving the motor.

  • Page 211: Ir Compensation (Ir Comp)

    Calibration IR COMPENSATION (IR COMP) The IR COMP trimpot 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 212 Calibration Figure 19. Recommended Torque and IR COMP Settings (actual settings may vary with each application)

  • Page 213: Acceleration (Accel)

    Calibration 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. ACCEL is factory set for the fastest acceleration time (full CCW). To set the acceleration time: 1.

  • Page 214: Deceleration (Decel)

    Calibration DECELERATION (DECEL) The DECEL setting determines the time the motor takes to ramp to a lower speed. See Specifications on page 1 for approximate deceleration times. DECEL is factory set for the fastest deceleration time (full CCW). To set the deceleration time: 1.

  • Page 215: Application Notes

    Application Notes Multiple fixed speeds Replace the speed adjust potentiometer with series resistors with a total series resistance of 10K ohms (Figure 19). Add a single pole, multi-position switch with the correct number of positions for the desired number of fixed speeds. Figure 20.

  • Page 216: Adjustable Speeds Using Potentiometers In Series

    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 20 shows a connection for fixed high and low speed adjust potentiometers. Figure 21.

  • Page 217: 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 21 shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations.

  • Page 218: Run/Jog Switch

    Application Notes RUN/JOG switch RUN/JOG switch option #1 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 single pole, normally closed, momentary operated pushbutton for the JOG pushbutton.

  • Page 219: Run/Jog Switch Option #2

    Application Notes RUN/JOG switch option #2 In the second wiring option, connect the RUN/JOG switch and the JOG pushbutton as shown in the Figure 23. 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). Press the JOG pushbutton to jog the motor.

  • Page 220: Leader-Follower Application

    Application Notes Leader-follower application In this application, use a PCM4 to monitor the speed of the leader motor (Figure 24). The PCM4 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 221 Application Notes Single speed potentiometer control of multiple drives Multiple drives can be controlled with a single speed adjust potentiometer using a PCM4 at the input of each drive to provide isolation (Figure 25). Optional ratio potentiometers can be used to scale the PCM4 output voltage, allowing independent control of each drive.

  • Page 222: Reversing

    Application Notes Reversing A dynamic brake may be used when reversing the motor direction (Figure 26). Use a three pole, three position switch rated for at least the maximum DC armature voltage and maximum braking current. Wait for the motor to stop completely before switching it to either the forward or reverse direction.

  • Page 223: Reversing With A Digi-Lok Controller

    Application Notes Reversing with a DIGI-LOK controller A DIGI-LOK controller, model DLC600, can be used in a reversing application. The DIGI-LOK must be inhibited while braking. Without the inhibit feature, the DIGI-LOK will continue to regulate. This will cause overshoot when the DIGI-LOK is switched back to the drive. Figure 27 shows the connection of the reversing circuit to a MM23000 series drive and to a DLC600.
