MM300 / MM500 Series
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.
For chassis models, connect a DC motor to terminals A1 and A2 as shown
in Figures 7 and 8 on pages 19 and 20. For enclosed models, connect a
DC motor to terminals 6 (A1) and 7 (A2) as shown in Figure 9 on page
21. Ensure that the motor voltage rating is consistent with the drive’s
output voltage.
Power Input
For chassis models MM301U and MM311U, connect the AC line power
leads to terminals L1 and L2 (115) if
using a 115 VAC line or to terminals
L1 and L2 (230) if using a 230 VAC line. Refer to Figure 7 on page 19. For
chassis model MM501U, connect the AC line power leads to terminals L1
and L2. Refer to Figure 8 on page 20.
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 Figures 7 and 8 on pages 19
and 20.
For enclosure models, connect the AC line power leads to screw terminals
1 (L1) and 3 (L2 115) if using a 115 VAC line or to terminals 1 (L1) and 2 (L2
230) if using a 230 VAC line. Refer to Figure 9 on page 21.
