6.5 PROFIdrive profile for PROFIBUS and PROFINET
Explanation
The motor brakes with the ramp-down time p1121 of the
ramp-function generator. The inverter switches off the motor
at standstill.
The inverter goes into the "ready" state. If, in addition
bit 3 = 1, then the inverter switches on the motor.
Switch off the motor immediately, the motor then coasts
down to a standstill.
The motor can be switched on (ON command).
Quick stop: The motor brakes with the OFF3 ramp-down
time p1135 down to standstill.
The motor can be switched on (ON command).
Immediately switch-off the motor (cancel pulses).
Switch-on the motor (pulses can be enabled).
The inverter immediately sets its ramp-function generator
output to 0.
The ramp-function generator can be enabled.
The output of the ramp-function generator stops at the actu-
al value.
The output of the ramp-function generator follows the set-
point.
The inverter brakes the motor with the ramp-down time
p1121 of the ramp-function generator.
The motor accelerates with the ramp-up time p1120 to the
setpoint.
Acknowledge fault. If the ON command is still active, the
inverter switches to the "closing lockout" state.
The inverter ignores the process data from the fieldbus.
Control via fieldbus, the inverter accepts the process data
from the fieldbus.
Invert the setpoint in the inverter.
Increase the setpoint saved in the motorized potentiometer.
Reduce the setpoint saved in the motorized potentiometer.
Changes over between settings for different operation inter-
faces (command data sets).
