READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT
DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a
qualified electrical technician install, adjust and service this equipment. Follow the National
Electrical Code and all other applicable electrical and safety codes, including the provisions of the
Occupational Safety and Health Act (OSHA), when installing equipment.
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 adjusting the calibration trim pots. Use
approved personal protection equipment and insulated tools if working on this drive with power
applied.
The drive is not diode-protected from reverse battery voltage. You must ensure that the positive
terminal is wired to BAT+ and the negative terminal is wired to BAT-.
Reduce the chance of an electrical fire, shock, or explosion by using proper grounding techniques,
over-current protection, thermal protection, and enclosure. Follow sound maintenance procedures.
Removing DC power is the only acceptable method for emergency stopping. Do not use
regenerative braking, decelerating to minimum speed, or coasting to a stop for emergency stopping.
They may not stop a drive that is malfunctioning. Removing DC power is the only acceptable method
for emergency stopping.
Applying and removing DC source voltage is recommended for infrequent starting and stopping of a
drive only. Regenerative braking, decelerating to minimum speed, or coasting to a stop is
recommended for frequent starts and stops. Frequent starting 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.
Under no circumstances should power and logic level wires be bundled together.
Be sure potentiometer tabs do no make contact with the potentiometer’s body. Grounding the
input may cause damage to the drive.

Installation
POWER
Motor
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired
direction, power down the drive and reverse these connections.
Wiring
Use 18 - 24 AWG wire for logic wiring.
Use 10 - 12 AWG wire for DC source (BAT+, BAT-) and motor (A1, A2) wiring.
BATTERY
Shielding Guidelines
As a general rule, Minarik Drives recommends shielding of all conductors. If it is not practical to shield
power conductors, Minarik Drives 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.
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.

LOGIC
Speed Potentiometer
Use a 10K ohm, 1/4 W potentiometer for speed control. Connect the counter-clockwise end of the
potentiometer to terminal 3, the wiper to terminal 2, and the clockwise end to terminal 1. If the
potentiometer works inveresly of desired functionality, (i.e. to increase motor speed, you must turn
the potentiometer counterclockwise), power off the drive and swap the terminal 1 and 3 connections.
Forward & Reverse Inhibit
Connect a forward inhibit switch to terminals 7 and 8 and a reverse inhibit switch to terminals 9 and 10.
Opening a connection regeneratively brakes the motor to a stop. The inhibits bypass the DECEL trim
pot. The forward inhibit switch has no effect if the motor is running in reverse, and vice versa. If the use
of only one inhibit switch is desired, jumper terminals 7 and 9 and then connect the switch to either
the forward or reverse inhibit input. If no inhibit switches are desired, jumper terminals 7 and 8 and
jumper terminals 9 and 10. Do not use the Inhibit functions for emergency stopping.
Enable
Connect an enable switch to terminals 4 and 6. Close the switch to run and open the switch to coast
the motor to a stop. The enable comes into effect regardless of direction. If no switch is desired,
jumper terminals 4 and 6. Do not use the Enable function for emergency stopping.
Direction
Connect a direction switch to terminals 5 and 6. Close the switch to change direction.

Fusing
Minarik Drives’s drives require an external line fuse for protection. Use fast acting fuses rated for at
least 150% of the maximum armature voltage and current. Fuse the positive terminal.
Connections
Input Power
Connect the DC input power leads to terminals BAT+ (positive) and BAT- (negative).
Connecting the DC input power backwards will cause damage to the drive.

0-5 VDC - If using a 0-5 VDC analog signal to vary the motor speed, whether in unidiectional mode
or bidirectional mode, leave jumper 10V SIG open.
0-10 VDC - If using a 0-10 VDC analog signal to vary the motor speed, whether in unidiectional mode
or bidirectional mode, place a jumper on 10V SIG.
Unidirectional Mode - In unidirectional mode, the potentiometer determines the speed of the motor.
Unidirectional Mode - The direction switch determines the direction. For Unidirectional Mode, leave
Unidirectional Mode - the jumper on the WIGWAG header open.
Bidirectional Mode - In bidirectional mode, the potentiometer determines the speed and the direction
Bidirectional Mode - of the motor:
Full CCW = Full Speed Reverse
50% = Stop / Zero Speed
Full CW = Full Speed Forward
Bidirectional Mode - Closing the direction switch will invert the potentiometer.
Full CCW = Full Speed Forward
50% = Stop / Zero Speed
Full CW = Full Speed Reverse
For Bidirectional mode, place a jumper on the WIGWAG header. Bidirectional Mode can also be
referred to as WigWag Mode.

Forward Maximum Speed (FWD SPD): The FWD SPD setting determines the maximum motor speed
in the forward direction (when A1 is positive with respect to A2). To calibrate the FWD SPD:
1. Set the FWD SPD trim pot full CCW.
2. Set the speed adjust potentiometer for maximum speed.
3. Adjust FWD SPD until the desired maximum speed is reached.
Motor Torque (MOTOR CL): The MOTOR CL setting determines the maximum torque for accelerating
and driving the motor in the forward and reverse directions. To calibrate the MOTOR CL:
1. With the power disconnected from the drive, connect a DC ammeter in series with the
1. armature.
2. Set the MOTOR CL trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer to maximum forward speed (full CW).
4. Carefully lock the motor armature. Be sure that the motor is firmly mounted.
5. Apply power source. The motor should be stopped.
6. Slowly adjust the MOTOR CL trim pot CW until the armature current is 150% of motor rated
6. armature current.
7. Turn the speed adjust potentiometer to minimum speed (full CCW).
8. Remove power source.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is no longer needed.
Control Methods
Potentiometer - If using a 10k potentiometer to vary the motor speed, whether in unidiectional mode
or bidirectional mode, leave jumper 10V SIG open.
Unidirectional Mode vs. Bidirectional (WigWag) Mode
To calibrate the MIN SPD in Bidirectional Mode:
1. Set the external speed pot to mid position. If using a 0-5VDC or a 0-10VDC, set the speed
1. command signal to 2.5VDC or 5VDC respectively.
2. Adjust the Min Speed trim pot until the motor stops rotating.
Reverse Maximum Speed (REV SPD): The REV SPD setting determines the maximum motor speed in
the reverse direction (when A2 is positive with respect to A1). To calibrate the REV SPD:
1. Set the REV SPD trim pot full CCW.
2. Set the speed adjust potentiometer for maximum speed.
3. Adjust REV SPD until the desired maximum speed is reached.

Operations
Minimum Speed (MIN SPEED): The MIN SPEED setting determines the minimum motor speed when
the speed adjust potentiometer is set for minimum speed. It is factory set for zero speed. To calibrate
the MIN SPEED in Unidirectional Mode:
1. Set the MIN SPEED trim pot full CCW.
2. Set the speed adjust potentiometer for minimum speed.
3. Adjust MIN SPEED until the desired minimum speed is reached or is just at the threshold of
3. rotation.
Power LED
Regen Torque (REGEN CL): The REGEN CL setting determines the maximum torque for decelerating
the motor and resisting an overhauling load in the forward and reverse directions. Turn the REGEN CL
trim pot CW to increase the regen current limit and CCW to decrease the regen current limit. See the
approximate settings below.
0.5 Amps at 12 / 36 VDC
1.0 Amp at 24 / 24 VDC
3.25 Amps at 12 / 36 VDC

IR Compensation (IR COMP): The IR COMP setting 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 potentiometer until 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 rating. The motor should slow down.
4. While keeping the load on the motor, rotate the IR COMP trim pot until the motor runs at the
4. speed measured in step 2. If the motor oscillates (overcompensation), 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.
Acceleration (ACCEL): The ACCEL setting determines the time the motor takes to ramp to a higher
speed. To calibrate the ACCEL, turn the ACCEL trim pot CW for a longer acceleration time and CCW for
a shorter acceleration time.
Deceleration (DECEL): The DECEL setting determines the time the motor takes to ramp to a lower
speed. To calibrate the DECEL, turn the DECEL trim pot CW for a longer deceleration time and CCW for
a shorter deceleration time.
