Moons' Applied Motion Products STR2 User manual

a. Wire the drive to the DC power source.
(do not apply power until all connections to the drive have been made)
Note, the STR2 accepts DC voltages from 12-48V.
b. Ensure a proper earth ground connection by using the screw
on the left side of the chassis.
*See the STR2 Hardware Manual for more information about power supply
and fuse selection.
Connect the drive to the motor. Four lead motors can be connected in only one way, as shown in Figure 1.
Eight lead motors can be connected in Series or Parallel, as shown in Figures 2 and 3.
If using a non-Applied Motion Products motor, please refer to your motor specs for wiring information.

NOTE: DIP switch setting changes will only take effect at power up. If changes to the DIP switches
are made while power is applied, cycle power off then on for the new settings to take effect.
Motor selection is done with the DIP switch block on the
narrow face of the drive. These switches are referred to
as B1 - B3 in the STR2 Hardware Manual.

The STR has a built in Self Test function. If switch A1 is
moved to the ON position the drive will automatically rotate
the motor back and forth, two turns in each direction. This
feature can be used to confirm that the motor is correctly
wired, selected and otherwise operational.
