are needed:
• Universal AC input of 80 to 265 VAC
• Pulse & Direction signal
• A compatible step motor

Connect to Power

Use the supplied connector to connect to the AC
supply according to the diagram below. Use 16
AWG wire for Line (L) and Neutral (N). Use 14 AWG

The SRAC8 has an internal 10A fast acting fuse.

Selecting the Motor

Each position of the 16-bit rotary selects a different motor, automatically setting the configuration parameters
in the drive. The SRAC8 drive comes programmed with up to 16 typical motors as factory defaults. Drives
can be customized with specially selected motors when required. Available options are listed
on the drive label. Each motor in the loaded database has unique settings to optimize the anti-
resonance.
If the motor selection is changed, the drive power supply will need to be cycled.
