Figure 8-4 Sequence control of the inverter when the motor is switched on and o󹪜
Inverter states S1 … S5c are de󹪝ned in the PROFIdrive pro󹪝le. The sequence control de󹪝nes the
transition from one state to another.

S1 The inverter waits for a new ON command.
The ON command is currently active. You must ac‐
tivate the ON command again in order that the in‐
verter exits the state.
S4 The motor is switched on.
S2 The inverter waits for a new command to switch on
the motor.

S5c
The motor is still switched on. The inverter brakes
the motor with the ramp-down time of the ramp-
function generator.
S3 The inverter waits for "Enable operation". The "Ena‐
ble operation" command is always active in the in‐
verter factory setting.
S5b The motor is still switched on. The inverter brakes
