To wire the STR4-8 Stepper Drive to a DC power supply, follow these steps:
1. Make sure you have a compatible stepper motor, a small flat blade screwdriver, and a suitable DC power supply (AMP recommends the PS150A24 or PS320A48).
2. Connect the drive to the DC power source. Ensure that all connections to the drive are made before applying power.
3. Do not alter any rotary or dip switch settings of the drive while power is applied, as this can cause permanent damage to the drive.
4. Note that the STR4 accepts DC voltages from 24-48V, while the STR8 accepts DC voltages from 24-75V.
5. Ensure a proper earth ground connection by using the xxxx on the left side of the chassis.
6. If using an external fuse, it is recommended to use the following in-line with the V+ connection:
- STR4: 3AG, 4 amp (Littlefuse 313004P)
- STR8: 3AG, 6.25 amp (Littlefuse 3136.25P)
For more detailed information about power supply and fuse selection, refer to the STR Hardware Manual.
