Page 9: Installation
Installation Mounting • Drive components are sensitive to electrostatic fields. Avoid contact with the circuit board directly. Hold 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 trimpots. •... -
Page 10: Heat Sinking
Line fusing Protect all Minarik drives with AC line fuses. Use fast acting AC line fuses rated for 250 volts, and approximately 150% – 200% of the maximum armature current. Fuse only the “hot”... -
Page 11: Speed Adjust Potentiometer
Installation Speed adjust potentiometer Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided (Figure 2). Install the circular insulating disk between the panel and the 10K ohm speed adjust potentiometer. Twist the speed adjust potentiometer wire to avoid picking up unwanted electrical noise. -
Page 12: Connections
LINE VOLTAGE Figure 3. XP-AC Connections ASSUMPTIONS: Minarik drives supply motor voltage from A+ and A– terminals. It is as- sumed throughout this manual that, when A+ is positive with respect to A–, the motor will rotate clockwise (CW) while looking at the output shaft protruding from the front of the motor. -

Page 14: Operation
Operation Startup Note: Before applying power, verify that no conductive material is present on the printed circuit board. To start the drive: Turn the speed adjust potentiometer full counterclockwise (CCW). If the drive is follow- ing a voltage signal, set the voltage signal to 0 VDC. Apply AC line voltage. -
Page 15: Decelerating To A Stop
Operation Decelerating to a stop A switch may be used to decelerate the motor to a stop. Connect the switch as shown in Figure 5. Close the switch between S1 and S2 to stop the motor from set speed. Open the switch to accelerate the motor to set speed. -
Page 16: Dynamic Braking
Operation Dynamic braking Dynamic braking may be used to rapidly stop a motor (Figure 6). For the simplest RUN/ BRAKE switch, use a double pole, double throw switch rated for at least the maximum DC armature voltage and maximum braking current. For the most reliable control scheme, use a relay with a delay on the make for the motor, and use a relay with a delay on the brake for S1/S2. - Page 17 Operation Size the dynamic brake resistor according to the motor current rating (see the table below). The dynamic brake resistance listed in the table is the smallest recommended resistance allowed to prevent possible demagnetization of the motor. The motor stops less rapidly with higher brake resistor values.

Page 18: Calibration
Calibration Each drive is factory calibrated to its maximum horsepower rating. Readjust the calibration trimpot settings to accommodate lower horsepower motors. All adjustments increase with CW rotation, and decrease with CCW rotation. Use a non-me- tallic screwdriver for calibration. Each trimpot is identified on the printed circuit board. MAX SPD The MAX SPD setting determines the motor speed when the speed adjust potentiometer is turned full CW. -
Page 19: Current Limit
Calibration CURRENT LIMIT The CURRENT LIMIT setting determines the maximum armature current output of the drive. It is factory set at 120% of rated motor current. Recalibrate the CURRENT LIMIT setting when using a lower horsepower motor. Refer to the recommended CURRENT LIMIT settings on page 14, or recalibrate using the following procedure: With the power disconnected from the drive, connect a DC ammeter (0–15 A minimum scale) in series with the armature. - Page 20 Calibration XP02-115AC XP05-115AC 1/8 HP 1/2 HP 90 VDC 90 VDC 1.3 ADC 5 ADC CURRENT IR COMP CURRENT IR COMP LIMIT LIMIT 1/10 HP 1/3 HP 90 VDC 90 VDC 1.1 ADC 3.5 ADC CURRENT IR COMP CURRENT IR COMP LIMIT LIMIT 1/20 HP...

Page 22: 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 10 shows the connection of two independent speed adjust potentiometers that can be mounted at two seperate operating stations. -

Page 24: Leader-Follower Application
Application Notes Leader-follower application In this application, use a PCM4 to monitor the speed of the leader motor (Figure 13). 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 25: Reversing
Application Notes Reversing A dynamic brake may be used when reversing the motor direction (Figure 15). Use a three pole, three positions switch rated for at least the maximum DC armature voltage and maxi- mum braking current. Wait for the motor to stop completely before switching it to either the forward or reverse direction. -
Page 26: Troubleshooting
Troubleshooting WARNING Dangerous voltages exist on the drive when it is powered. When possible, disconnect the AC line voltage from the drive while troubleshooting. Be alert. High voltages can cause serious or fatal injury. Perform the following steps before starting any procedure in this section: •... - Page 27 Troubleshooting Fuse blows or circuit breaker trips Check all wiring for shorts, grounds, or misconnections. Check that the drive is configured to match the motor rating. Check that the motor is not jammed or restricted from movement. Check that the fuse size is correct for the motor being driven. Motor runs too fast at the maximum speed setting Check that the MAX SPD setting is not set too high.
- Page 28 Troubleshooting Motor only runs at full speed Check that S2 and S3 are not shorted together. For additional assistance, contact your local Minarik Drives distributor, or the factory direct: (800) MINARIK or (800) 646-2745.
