the power supply.
● OFF2 or OFF3 is selected.
S2
The prerequisites for switching the motor on are satisfied.
S3
The inverter waits for "enable operation".
S4
The motor is switched on.
S51
The inverter brakes the motor with the ramp-down time of the ramp-function generator.
S52
The inverter brakes the motor with the OFF3 ramp-down time.
The abbreviations S1 … S5b to identify the inverter states are defined in the PROFIdrive profile.
