01
Enable right
The device delivers an output signal with the rotation field right if a positive
setpoint is present. 0
® 1 Flank (P428 = 0)
High
02
Enable left
The device delivers an output signal with the rotation field left if a positive
setpoint is present. 0
® 1 Flank (P428 = 0)
High
If the drive is to start up automatically when the mains is switched on (P428 = 1) a permanent High level for enabling must be provided (bridge
between DIN1 and the control voltage output).
If the functions "Enable right" and "Enable left" are actuated simultaneously, the FI is blocked.
If the frequency controller is in fault status but the cause of the fault no longer exists, the error message is acknowledged with a 1
® 0 flank .
03
Change of rotation direction
Causes the rotation field to change direction, combined with Enable right or left. High
