7. Commissioning the functions of the digital AC servo drive
Preselecting the servo
motor’s direction of rotation A positive voltage at the differential input E1 against E2 will cause the
motor to rotate clockwise (looking at the motor shaft)
A negative voltage at the differential input E1 against E2 will cause the
motor to rotate counter clockwise.
DO NOT attempt to change the direction of rotation of the motor
by switching two cores in the motor power cable. This may
destroy the motor.
