Quick Start Guide
This Quick Start Guide is intended for customers who are familiar
with installing and operating the MMBOSS series drive. For
calibration, troubleshooting and application notes information,
refer to document number 250-0288, the MMBOSS User’s
Manual.
Connections
Warning
Do not install, remove, or rewire this equipment with power
applied. Failure to heed this directive may result in fire or
serious injury.
Do not reverse power input leads or apply reverse voltage at
the drive terminals. The drive will be damaged.
Minarik strongly recommends the installation of a master
power switch in the voltage input line, as shown in Figure 1.
The switch contacts should be rated at a minimum of
200% of motor nameplate current.
Motor
Connect a three-phase, low-voltage brushless motor to PCB
terminals U, V and W, as shown in Figure 1. Connect motor
phase A (or phase 1) to drive terminal U. Connect motor phase
B (or phase 2) to drive terminal V. Connect motor phase C
(or phase 3) to drive terminal W.
Power input
Connect the DC input power leads to PCB terminals BUS+ and
BUS-. Connect the positive (+ or high) lead to BUS+. Connect
the negative (- or common) lead to BUS-. Minarik strongly
recommends a master power switch for emergency use.
Line fuse
Wire an external line fuse between the stop switch (if installed)
and the BUS+ terminal. The line fuse should be rated at 75 volts
and 150 - 200% of maximum motor nameplate current.
Connection to TB502
Connections to TB502 are identical to TB501. Refer to Figure 2
on page 4 for TB502 terminal assignments. Contact your Minarik
representative for assistance in connecting to TB502.

Optional switch connections
Connect the following switches to the terminal plug as shown in
Figure 3 (page 6).
ENABLE/DISABLE switch
Install a single-pole, single-throw switch between the ENABLE
and COM terminals (Figure 3). Close the switch to disable the
drive and coast the motor to a stop. Leave open to enable the
drive and run the motor.
RUN/BRAKE switch
Install a single-pole, single-throw switch between the BRAKE
and COM terminals (Figure 3). Open the switch to brake the
motor to a stop. Close the switch to run the motor and accelerate
to set speed.
DIRECTION switch
Install a single-pole, single-throw switch between the DIR and
COM terminals (Figure 3). Open or close the switch as required
to change direction.

Operation
Before applying power:
• Verify that no conductive material is present on the printed
circuit board.
• Ensure that all jumpers are properly set.
Startup
1. Verify that no conductive material is present on the PCB.
2. Check that the enable/disable switch is in the enable position
(open).
3. Check that the run/brake switch is in the run position (closed).
4. Set the DIR switch to the direction you want the motor to
rotate upon startup.
5. Set the speed adjust potentiometer to zero (fully CCW). If a
voltage signal is used, set to zero.
6. Apply DC voltage input to the drive.
7. Slowly advance the speed adjust potentiometer so that motor
speed increases in the desired direction. If a voltage signal is
used, slowly increase the signal. The motor will slowly
accelerate as the potentiometer is turned CW, or as the voltage
signal is increased. Continue until the desired speed is
reached.

Reversing
To change direction, set the DIR switch to the opposite position.
To avoid motor damage from high braking currents, always brake
the motor to a stop before reversing. An alternative is to close the
ENABLE/DISABLE switch or remove power to the drive before
reversing. Always wait for the motor to come to a stop before
reversing.
Drive shutdown
To shut down the drive:
1. Set the input signal to minimum or zero speed.
2. Set the RUN/BRAKE switch to the BRAKE (open) position.
3. Set the ENABLE/DISABLE switch to the DISABLE (closed)
position.
4. Remove line voltage.
To coast the motor to a stop, remove power to the drive. You
may also close the ENABLE/DISABLE switch to coast to a stop.
