6.2.1 Digital Input (DI)
Control signal terminals 2, 3, 4, and 6 can be used as digital inputs (DI). The
digital inputs‘ function and mode of operation are configured in parameter
P-15.
Example
Desired options:
• Clockwise rotating field (FWD),
• Anticlockwise rotating field (REV),
• external fault,
• Setpoint value via AI1.

Table 14: Digital input wiring
• DI1 (control signal terminal 2): FWD (Forward = Start enable clockwise
rotating field)
• DI2 (control signal terminal 3): REV (Reverse = Start enable anti-clock-
wise rotating field)
• DI3 (control signal terminal 4): external fault
• AI1 (control signal terminal 6): analog setpoint value
