Example: Activation via command (only when disabled)
Activation method 0x4046 (P755.00) = "Via command (disable required) [0]":
–
Switches S3 and S4 serve to select the parameter set (see the following table).
–
Switch S2 activates the change-over. Since the change-over is activated with a rising edge, a button (normally-open contact) can be used instead of a switch.
–
Change-over is only possible if the motor is not started (switch S1 open).
