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.
Do not disconnect any of the motor leads from the drive
unless power is removed. Opening any one motor lead
may destroy the drive.
This drive is not diode-protected from reverse battery
voltage. You must assure that POS (+) is wired to +VDC
IN and NEG (–) is wired to –VDC IN.
This product does not have internal solid state motor overload protection. It does not contain speed-sensitive overload
protection, thermal memory retention, or provisions to
receive and act upon signals from remote devices for over
temperature protection. If motor overload protection is
needed in the end-use product, it needs to be provided by
additional equipment in accordance with NEC standards.
Use 18 AWG wire for speed adjust potentiometer wiring. Size the DC
voltage input and motor wire according to the following chart:

Shielding guidelines
Warning
Under no circumstances should power and logic leads be
bundled together. Induced voltage can cause unpredictable
behavior in any electronic device, including motor controls.
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 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 a device on the drive, ground
the shield at the end away from the drive. Do not ground both
ends of the shield.
If the drive continues to pick up noise after grounding the shield,
it may be necessary to add AC line filtering devices, or to mount
the drive in a less noisy environment.
Logic wires from other input devices, such as motion controllers
and PLL velocity controllers, must be separated from power lines
in the same manner as the logic I/O on this drive.
Installation
Heat sinking
XP10–DC series drives require an additional heat sink when the
continuous armature current is above 5 ADC. XP32–DC and
XP60–DC series drives require an additional heat sink when the
continuous armature current is above 20 ADC. All other chassis
drives have sufficient heat sinking in their basic configurations.
Use Minarik Drives part number 223–0159 for XP10, XP32 and
XP60 series drives when the above conditions are met. Apply a
thermally conductive heat sink compound (such as Dow Corning®
340 Heat Sink Compound) between the drive chassis and heat
sink surface for optimum heat transfer.
Fuse / Circuit breaker protection
All XP-DC 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.
Connect the fuse or circuit breaker to the VDC+ IN side of the
DC voltage input.

Installation
Switch 501 (SW501)
XP10-, XP16-, XP32- and XP60-series drives are shipped with
SW501 open (no jumper applied). This allows you to use 48
VDC motors with the XP10–36/48DC and XP16–36/48DC, or
24 VDC motors with the XP32–12/24DC and XP60–12/24DC.
To use lower voltage DC motors (36 VDC or 12 VDC,
respectively) jumper pins 2 and 3 with the jumper provided. See
Figure 3 for the location of SW501.

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 4 on Page 10). 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. If speed adjust potentiometer wires are
longer than 18 in. (457 mm), use shielded cable. Keep speed
adjust potentiometer wires separate from power leads (L1, L2,
A1, A2).

Connections
Warning
Do not connect this equipment with power applied.
Failure to heed this directive may result in fire or serious
injury.
Minarik Drives strongly recommends the installation of a
master power switch in the voltage input line, as shown
in Figure 6, page 13. The switch contacts should be rated
at a minimum of 200% of motor nameplate current and
150% of the input voltage.
Power, fuse and motor connections
Connect the power input leads, an external line fuse and a motor
to the drive’s printed circuit board (PCB) as shown in Figure 6,
page 13.
Motor
XP-DC drives supply motor voltage from the 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 opposite of the desired rotation, simply reverse the
wiring of A1 and A2.
11
12
Connect a DC motor to PCB terminals A1 and A2 as shown in
Figure 6, page 13. Ensure that the motor voltage rating is
consistent with the drive’s output voltage.
Power input
Warning
This drive is not diode-protected from reverse battery
voltage. You must assure that POS (+) is wired to +VDC
IN and NEG (–) is wired to –VDC IN.
Connect the DC power leads to terminals + VDC IN and - VDC
IN, or to a single-throw, single-pole master power switch as
shown in Figure 6, page 13 (recommended).
Line fuse
Wire an external line fuse between the stop switch (if installed)
and the + VDC IN terminal on the circuit board. The line fuse(s)
should be rated at 150% of input voltage and 150 - 200% of
maximum motor nameplate current.

Voltage follower
Instead of using a speed adjust potentiometer, the drive may be
wired to follow an isolated (floating, or differential) 0–10 VDC
signal that is isolated from earth ground (Figure 7). Connect the
signal input (+) to S2. Connect the signal common (–) to S1.
Make no connection to S3. A potentiometer can be used to scale
the analog input voltage. Use a battery to achieve greater linearity
and control.

Before applying power
• Verify that no conductive material is present on the printed
circuit board.
• Ensure that all jumpers are properly set.
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.
Operation
Startup and shutdown
To start the drive:
1. Turn the speed adjust potentiometer full counterclockwise
(CCW).
2. Apply DC voltage input.
3. Slowly advance the speed adjust potentiometer clockwise
(CW). The motor slowly accelerates as the potentiometer is
turned CW. Continue until the desired speed is reached.
4. Remove DC voltage input from the drive to coast the motor to
a stop.
If the motor or drive does not perform as described, disconnect
the DC voltage input immediately. Refer to the Troubleshooting
section (page 29) for further assistance.
16
Operation
Operation
Starting and stopping methods
Warning!
Decelerating to minimum speed, regenerative braking, or
coasting to a stop is recommended for frequent starts and
stops. Do not use any of these methods for emergency
stopping. They may not stop a drive that is malfunctioning.
Removing DC line power is the only acceptable method for
emergency stopping.
For this reason, Minarik Drives strongly recommends
installing an emergency stop switch (see Connections on page 11).
Frequent decelerating to minimum speed produces high torque.
This may cause damage to motors, especially gearmotors that are
not properly sized for the application.
Automatic restart upon power restoration
All drives automatically run to set speed when power is applied.
Line starting and line stopping
Line starting and line stopping (applying and removing DC
voltage input) is recommended for infrequent starting and
stopping of a drive only. When DC voltage input is applied to the
drive, the motor accelerates to the speed set by the speed adjust
potentiometer. When DC voltage input is removed, the motor
coasts to a stop.

Figure 8. Run/Decelerate to Zero Speed Switch
Decelerating to zero speed
A single pole, single throw switch may be used to decelerate a
motor to zero speed (see Figure 8). Close the switch between S1
and S2 to decelerate the motor from set speed to zero speed. Open
the switch to accelerate the motor from zero speed to set speed.
The ACCEL/DECEL trimpot setting determines the rate at which
the motor accelerates and decelerates.

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. BE ALERT.
High voltages can cause serious or fatal injury.
Each drive is factory calibrated to its maximum armature voltage
and current rating. Readjust the calibration trimpot settings to
accommodate a motor with a lower armature and current rating.
All adjustments increase with clockwise rotation (CW), and
decrease with counter-clockwise rotation (CCW). Use a nonmetallic screwdriver for calibration. Each trimpot is identified on
the printed circuit board. (see Figure 9)

MAX SPD
The MAX SPD setting determines the motor speed when the
speed adjust potentiometer is turned full CW. It is factory set for
maximum rated speed.
To calibrate MAX SPD:
1. Set the MAX SPD trimpot full CCW.
2. Apply power to the drive and turn the speed adjust
potentiometer full CW. If an input voltage signal is used
instead of a speed adjust pot, set the input signal to maximum.
3. Adjust the MAX SPD trimpot until the desired maximum
motor speed is reached.

Calibration
21
ACC/DEC
The ACC/DEC setting determines the time the motor takes to
accelerate to a higher speed, or decelerate to a lower speed. See
Specifications on page 1 for approximate acceleration and
deceleration times. The ACC/DEC setting is factory set to its
minimum value (full CCW).
To calibrate ACC/DEC:
1. Set the ACC/DEC trimpot full CCW.
2. Apply power to the drive and turn the speed adjust
potentiometer full CW. If an input voltage signal is used
instead of a speed adjust pot, set the input signal to maximum.
Note the time that the drive takes to accelerate to the desired
speed.
3. Adjust the ACC/DEC trimpot until the desired acceleration
time is reached. Turn the ACC/DEC trimpot CW to increase
the acceleration and deceleration time, and CCW to decrease
the acceleration and deceleration time.
Calibration
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. Set the IR COMP trimpot to minimum (full CCW).
2. Rotate the speed adjust potentiometer until the motor runs at
midspeed without load (for example, 900 RPM for an 1800
RPM motor). A hand held 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
trimpot until the motor runs at the speed measured in step 2.
If the motor oscillates (overcompensation), the IR COMP
trimpot may be set too high (CW). T urn the IR COMP trimpot
CCW to stabilize the motor.
5. Unload the motor.
22
Calibration
23
The TQ LIMIT setting determines the maximum armature current
output of the drive.
Recalibrate the TQ LIMIT setting when a lower current limit
is required. Refer to the TQ LIMIT settings in Figure 10, or
recalibrate using the following procedure:
1. With the power disconnected from the control, connect a DC
ammeter in series with the armature.
2. Set the TQ LIMIT trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer to maximum (full CW).
4. Carefully lock the motor armature. Be sure that the motor is
firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the TQ LIMIT trimpot CW slowly until the
armature current is 120% of motor rated armature current.
7. Set the speed adjust potentiometer to minimum
8. Remove the power from the drive and unlock the motor shaft.
9. Remove the ammeter in series with the motor armature if it is
no longer needed and re-apply power to the drive.
TQ LIMIT
Warning
TORQUE 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 Minarik representative.

Potentiometer
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 single pole, normally closed, momentary operated
pushbutton for the JOG pushbutton (see Figure 14). When the
RUN/JOG switch is set to JOG, the motor decelerates to zero
speed. Press the JOG pushbutton to jog the motor . Return the
RUN/JOG switch to RUN for normal operation.
Application Notes
Troubleshooting
Warning
Dangerous voltages exist on the drive when it is powered.
When possible, disconnect the drive while troubleshooting.
High voltages can cause serious or fatal injury.
Before troubleshooting
Perform the following steps before starting any procedure in this
section:
1. Disconnect DC voltage input from the drive.
2. Check the drive closely for damaged components.
3. Check that no conductive or other foreign material has become
lodged on the printed circuit board.
4. Verify that all connections are correct and in good condition.
5. Verify that there are no short circuits or grounded connections.
6. Check that the drive’s rated armature voltage and current is
consistent with the motor ratings.

Motor does not run
1. Check for blown fuses or tripped circuit breaker .
2. Verify that the speed adjust potentiometer is not set to zero
position.
3. Verify that the drive is receiving DC voltage input.
4. Check that the drive is not in current limit. It may be necessary
to increase the TQ LIMIT setting if it is set to a value lower
than the current rating of the motor. (see page 23)
5. Check that the motor is not jammed or restricted from
movement.
Fuse blows or circuit breaker trips
1. Check all wiring for shorts, grounds, or misconnections.
2. Check that the drive is configured to match the motor rating.
3. Check that the motor is not jammed or restricted from
movement.
4. Check that the fuse or circuit breaker size is correct for the
motor being driven.
Motor runs too fast at the maximum speed setting
1. Check that the MAX SPD setting is not set too high. (see
page 20)
Troubleshooting

Troubleshooting
Motor runs in the opposite direction
1. Remove DC voltage input.
2. Reverse connections to the motor armature. (see page 1 1)
Motor is unstable under load
1. Readjust the IR COMP setting slightly CCW until motor speed
is stabilized. (see page 22)
Motor slows under load
1. Check that the drive has been correctly calibrated for the
motor.
2. Check that the motor is not overloaded.
3. Readjust the IR COMP slightly CW until motor runs at proper
speed. (see page 22)
