Connect to the Power Supply
If the power supply does not have a fuse
on the output or some kind of short circuit
current limiting device, a 4 amp fast acting
fuse should be installed in line with the “+”
power supply lead.
Connect the motor power supply “+” ter-
minal to the drive terminal labeled “V+”.
Connect the power supply “-” to the drive
terminal labeled “V-”.
Be careful not to reverse the wires.
Selecting the Motor
Each position of the 16-bit rotary switch selects a different motor, and automatically sets the confi guration
parameters in the drive. The SR8-Plus drive comes programmed with up to 8 typical motors as factory de-
faults. Drives can be customized with specially selected motors when required. Available options are on the
drive label.
The switch also selects a low or high inertia for each motor to allow for various load conditions.
The low setting is 1:1, and the high setting is 10:1. 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.
