Connecting to a Motor
Connect the drive to the motor. Four lead
motors can be connected
in only one way. If using a
non MOONS’ motor,
consult the motor specs
for wiring information.
2
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
for Earth Ground (G).
The SRAC8 has an internal 10A fast acting fuse.
Care should be taken when working with high voltages.
4
Selecting the Motor
Each position of the 16-bit rotary selects a different motor, automatically setting the conguration 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.
