Figure 6-3 Sequence control of the inverter when the motor is switched on and off
Inverter states S1 … S5c are defined in the PROFIdrive profile. The sequence control defines
the transition from one state to another.
Table 6-1 Inverter states
The motor is switched off The motor is switched on
Current does not flow in the motor and the motor does not
generate any torque
Current flows in the motor and the motor generates a torque
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.
S5a,
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 "En‐
able operation" command is always active in the
inverter factory setting.
S5b The motor is still switched on. The inverter brakes
the motor with the OFF3 ramp-down time.
