Connecting to a Motor
Never connect the motor to or disconnect it from the drive when the power is on. Never connect the motor
leads to ground or to a power supply.
A 3-phase step motor’s winding is either a star or delta con guration. The 3SR8-Plus drives and MOONS’
motors are set up for delta connection. Connect the motor leads to the drive screw terminals U, V, and W.
Any two leads may also be reversed to change the motor’s running direction. For a star con guration,
consult the documentation for that motor.

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 con guration
parameters in the drive. The 3SR8-Plus drive comes programmed with up to 5 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.
