STR2 Quick Setup Guide
To begin, make sure you have the following equipment:
▪
A compatible stepper motor.
▪
A small flat blade screwdriver for tightening the connectors (included).
▪
A suitable DC power supply. AMP recommends the PS50A24, PS150A24 or PS320A48 available from Applied Motion.
Step 1 - wiring the DC supply
Wiring the Drive
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 24-48V.
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.
Step 2 - wiring the motor
920-0060 A
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.
