WARNING!
Do not install, rewire, or remove this control with input power
applied. Failure to heed this warning may result in fire, explosion,
or serious injury. Make sure you read and understand the Safety
Precautions on page i before attempting to install this product.
Heat Sinking
Models MMXL10-D240AC and MMXL10-D240AC-PCM require an
additional heat sink when the continuous armature current is above 5
amps. Use Minarik Drives heat sink kit part number 223-0159. All other
chassis drives have sufficient heat sinking in their basic configuration.
Use a thermally conductive heat sink compound (such as Dow Corning®
340 Heat Sink Compound) between the chassis and the heat sink surface
for optimum heat transfer.
5
MMXL Series
Mounting
• Drive components are sensitive to electrostatic discharge. Avoid
direct contact with the circuit board. Hold the drive by the chassis
or heat sink only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminals and calibration
trim pots.
• Mount the drive away from heat sources. Operate the drive within
the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of the
drive.
• Mount the drive with its board in either a horizontal or vertical
plane. Eight 0.19” (5 mm) wide slots in the chassis accept #8 pan
head screws. Fasten either the large base or the narrow flange of
the chassis to the subplate.
• The chassis should be earth grounded. Use a star washer beneath
the head of at least one of the mounting screws to penetrate the
anodized surface and to reach bare metal.

Speed Adjust Potentiometer

!
WARNING!
Be sure that the potentiometer tabs do not make contact with the
potentiometer’s body. Grounding the input will cause damage to
the drive.
If using a remote potentiometer with a chassis drive, mount the speed
adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware
provided (Figure 3). 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 the speed adjust potentiometer wires are longer than
18 in. (46 cm), use shielded cable. Keep the speed adjust potentiometer
wires separate from power leads (L1, L2, A1, A2).

WARNING!
Do not install, rewire, or remove this control with input power
applied. Failure to heed this warning may result in fire, explosion,
or serious injury.
Circuit potentials are at 115 or 230 VAC above 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 or the drive is disabled. Opening any one
motor lead while the drive is running may destroy the drive.
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 signal from remote devices for over temperature
protection. If motor over protection is needed in the end-use
product, it needs to be provided by additional equipment in
accordance with NEC standards.
• Use 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for
AC line and motor wiring.

MMXL Series
Shielding Guidelines

!
WARNING!
Under no circumstances should power and logic level 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, it is recommended
to shield all logic-level leads. If shielding of all 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 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.

MMXL Series
Line Fusing
Chassis drives should be fused for protection. Use fast acting fuses rated
for 250 VAC or higher and 150% of maximum armature current. Fuse HOT
L1 only when the line voltage is 115 VAC. Fuse both L1 and L2 when the
line voltage is 230 VAC. Table 1 lists the recommended line fuse sizes.

Connections

!
WARNING!
Do not connect this equipment with power applied. Failure to
heed this warning may result in fire, explosion, or serious injury.
Minarik Drives strongly recommends the installation of a
master power switch in the voltage input line, as shown in
Figure 8 (page 16). The switch contacts should be rated at a
minimum of 200% of motor nameplate current and 250 volts.
This power switch is provided with NEMA 1 and NEMA 4X models.
Power Input
For chassis models, connect the AC line power leads to terminals L1 and
L2. Minarik Drives recommends the use of a single-throw, double-pole
master power switch. The switch should be rated at a minimum of 250
volts and 200% of motor current. Refer to Figure 5 on page 14.
Motor
Drives supply motor armature voltage from 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 the motor does not
spin in the desired direction, remove power and reverse the A1 and A2
connections.
Connect a DC motor to terminals A1 and A2 as shown in Figure 5 on page
14. Ensure that the motor voltage rating is consistent with the drive’s
output voltage.
11
MMXL Series
Speed Adjust Potentiometer
Use a 10K ohm, 1/4 W potentiometer for speed control. Connect the
counter-clockwise end of the potentiometer to S1, the wiper to S2, and
the clockwise end to S3. If the potentiometer works inversely of the
desired functionality (e.g. to increase motor speed you must turn the
potentiometer counterclockwise), power off the drive and swap the S1
and S3 connections. Refer to Figure 5 on page 14.
12
MMXL Series
Analog Input Signal
Instead of using a speed adjust potentiometer, non -PCM models may be
wired to follow an analog input voltage signal that is isolated from earth
ground. -PCM models may be wired to follow an analog input voltage
signal that is either isolated or non-isolated from earth ground (Figure 9).
Connect the signal common (–) to S1. Connect the signal reference (+) to
S2. Make no connection to S3. A potentiometer can be used to scale the
analog input voltage. An interface device, such as Minarik Drives model
PCM4, may be used to scale and isolate an analog input voltage.
An analog input voltage range of 0–5 VDC is required to produce an
armature voltage range of 0–130 VDC with 115 VAC line voltage or 0–240
VDC with 230 VAC line voltage.

Section 4. 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
and may cause damage to the transformer. If the switches are
improperly set to a higher voltage position, the motor will
overspeed, which may cause motor damage, or result in bodily
injury or loss of life.
Dangerous voltages exist on the drive when it is powered. BE
ALERT. High voltages can cause serious or fatal injury. For your
safety, use personal protective equipment (PPE) when operating
this drive.
If the motor or drive does not perform as described, disconnect
the AC line voltage immediately. Refer to the Troubleshooting
section, page 39, for further assistance.
Before Applying Power
1. Verify that no foreign conductive material is present on the
printed circuit board.
2. Ensure that all switches and jumpers are properly set.
15
MMXL Series
Startup
1.
Turn the speed adjust potentiometer full counterclockwise
(CCW) or set the input voltage signal to minimum.
2. Apply AC line voltage.
3. Slowly advance the speed adjust potentiometer clockwise
(CW) or increase the input voltage signal. The motor slowly
accelerates as the potentiometer is turned CW or as the input
voltage signal is increased. Continue until the desired speed is
reached.
4.
16
Remove AC line voltage from the drive to coast the motor to a
stop.
MMXL Series
Starting and Stopping Methods

!
WARNING!
Dynamic braking, coasting to a stop, or decelerating to minimum
speed 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 AC line power (both
lines) is the only acceptable method for emergency stopping.
For this reason, Minarik Drives strongly recommends installing
an emergency stop switch on both AC line inputs (see Figure 5
on page 14).
Frequent starting and stopping can produce 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 and the
inhibit is not active.
Line Starting and Stopping
Line starting and stopping (applying and removing AC line voltage) is
recommended for infrequent starting and stopping of a drive only. When
AC line voltage is applied to the drive, the motor accelerates to the speed
set by the speed adjust potentiometer or analog signal. When AC line
voltage is removed, the motor coasts to a stop.
17
MMXL Series
Dynamic Braking

!
WARNING!
Wait for the motor to completely stop before switching back to
RUN. This will prevent high armature currents from damaging
the motor or drive.
Dynamic braking may be used to rapidly stop a motor (Figure 6 on page
19). For the RUN/BRAKE switch, use a two pole, two position switch
rated for at least the armature voltage rating and 150% of the armature
current rating. For the dynamic brake resistor, use a 40 watt minimum,
high power, wirewound resistor.
Sizing the dynamic brake resistor depends on load inertia, motor voltage,
and braking time. Use a lower-value, higher-wattage dynamic brake
resistor to stop a motor more rapidly. Refer to Table 2 on page 19 for
recommended dynamic brake resistor sizes.

For motors rated 1/17 horsepower and lower, a brake resistor is not
necessary since the armature resistance is high enough to stop the
motor without demagnetization. Replace the dynamic brake with
12-gauge wire.

Inhibit Terminals
Close the INHIBIT to coast the motor to a stop (see Figure 7 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. Use shielded cable if the inhibit wires are
longer than 18 inches (46 cm). If shielded cable is used, ground only one
end of the shield to earth ground. Do not ground both ends of the shield.
Minarik Drives offers two accessory plug harnesses for connecting to
the INHIBIT terminals: part number 201-0024 [plug with 18 in. (46 cm)
leads]; and part number 201-0079 [plug with 36 in. (91 cm) leads].

Decelerating to Minimum Speed
The switch shown in Figure 8 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 trim pot setting. If the MIN SPD trim pot is set full CCW, the
motor decelerates to zero speed when the switch between S1 and S2 is
closed. The DECEL trim pot setting determines the rate at which the drive
decelerates. By opening the switch, the motor accelerates to set speed at
a rate determined by the ACCEL trim pot setting.

Section 5. Calibration

!
WARNING!
Dangerous voltages exist on the drive when it is powered. When
possible, disconnect the voltage input from the drive before
adjusting the trim pots. If the trim pots 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.
MMXL series drives have user-adjustable trim pots. Each drive is factory
calibrated to its maximum current rating. Readjust the calibration trim
pot settings to accommodate lower current rated motors.
All adjustments increase with CW rotation, and decrease with CCW
rotation. Use a non-metallic screwdriver for calibration. Each trim pot is
identified on the printed circuit board.
22
MMXL Series
Minimum Speed (MIN SPD)
The MIN SPD setting determines the minimum motor speed when the
speed adjust potentiometer or input voltage signal is set for minimum
speed. It is factory set for zero speed.
To calibrate the MIN SPD:
1.
Set the MIN SPD trim pot full CCW.
2. Set the speed adjust potentiometer or input voltage signal for
minimum speed.
3.
Adjust MIN SPD until the desired minimum speed is reached or
is just at the threshold of rotation.
Maximum Speed (MAX SPD)
The MAX SPD setting determines the maximum motor speed when the
speed adjust potentiometer or input voltage signal is set for maximum
speed.
To calibrate MAX SPD:
1.
Set the MAX SPD trim pot full CCW.
2.
Set the speed adjust potentiometer or input voltage signal for
maximum speed.
3. Adjust MAX SPD until the desired maximum speed is reached.
Note: Check the MIN SPD and MAX SPD adjustments after recalibrating
to verify that the motor runs at the desired minimum and maximum
speed.
23
MMXL Series
Torque (CURRENT LIMIT)

!
WARNING!
CURRENT LIMIT 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 Drives representative for assistance.
The CURRENT LIMIT setting determines the maximum torque for
accelerating and driving the motor. To calibrate CURRENT LIMIT, refer to
the recommended CURRENT LIMIT settings in Figures 9 through 11 on
pages 26 through 28 or use the following procedure:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the CURRENT LIMIT trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer full CW or input voltage
signal to maximum speed.
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 CURRENT LIMIT trim pot CW until the
armature current is 150% of motor rated armature current.
7. Turn the speed adjust potentiometer CCW or decrease the
input voltage signal.
8. Remove line power.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is
no longer needed.
24
MMXL Series
IR Compensation (IR COMP)
The IR COMP setting determines the degree to which motor speed is held
constant as the motor load changes.
Use the following procedure to recalibrate the IR COMP setting:
1.
Set the IR COMP trim pot to minimum (full CCW).
2. Increase the speed adjust potentiometer or input voltage signal
until the motor runs at midspeed without load (for example,
900 RPM for an 1800 RPM motor). A 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 speed measured in step 2. If
the motor oscillates (overcompensation), the IR COMP trim pot

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 shortest acceleration time (full CCW).
To set the acceleration time:
1.
Set the speed adjust potentiometer or input voltage signal for
minimum speed. The motor should run at minimum speed.
2.
Set the speed adjust potentiometer or input voltage signal for
maximum speed. Measure the time it takes the motor to go
from minimum to maximum speed.
3. If the time measured in step 2 is not the desired acceleration
time, turn the ACCEL trim pot CW for a longer acceleration time
or CCW for a shorter acceleration time. Repeat steps 1 through
2 until the acceleration time is correct.
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 shortest deceleration time (full CCW).
To set the deceleration time:
1.
Set the speed adjust potentiometer or input voltage signal for
maximum speed. The motor should run at maximum speed.
2. Set the speed adjust potentiometer or input voltage signal for
minimum speed. Measure the time it takes the motor to go
from maximum to minimum speed.
3. If the time measured in step 2 is not the desired deceleration
time, turn the DECEL trim pot CW for a longer deceleration time
or CCW for a shorter deceleration time. Repeat steps 1 through
2 until the deceleration time is correct.

RUN/JOG Switch - Inhibit Connection
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.
Connect the RUN/JOG switch and JOG pushbutton to the inhibit plug
as shown in Figure 15. The motor coasts to a stop when the RUN/JOG
switch is set to JOG. Press the JOG pushbutton to jog the motor. Return
the RUN/JOG switch to RUN for normal operation.

Leader-Follower Application
In this application, use a PCM4 to monitor the speed of the leader motor
(Figure 17). 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. An optional ratio potentiometer may be used to scale
the PCM4 output voltage.

Single Speed Potentiometer Control Of Multiple Drives
Multiple drives can be controlled with a single speed adjust potentiometer
using a USIM-8 at the input of each drive to provide isolation (Figure 18).
Optional ratio potentiometers can be used to scale the USIM-8 output
voltage, allowing independent control of each drive.
