How to Control the Frequenc...
Bit 12, Drive OK/Stopped, autostart
When bit 12 = "0", there is no temporary overloading of the
inverter.
When bit 12 = "1", the inverter has stopped due to
overloading. However, the frequency converter has not
switched off (trip) and will start again after the overloading
has ended.
Bit 13, Voltage OK/Voltage exceeded
When bit 13 = "0", the voltage limits of the frequency
converter are not exceeded.
When bit 13 = "1", the direct voltage in the intermediate
circuit of the frequency converter is too low or too high.
6.4.3 PROFIdrive State - Transition Diagram
6 6
In the PROFIdrive Control profile, the control bits 0 to 3 perform the basic start-up/power down functions, whereas the control
bits 4 to 15 perform application-oriented control.
Illustration 6.1 shows the basic state-transition diagram, where control bits 0 to 3 control the transitions, and the corresponding
status bit indicates the actual state. The black bullets indicate the priority of the control signals, where fewer bullets indicate
lower priority, and more bullets indicate higher priority.

PROFINET Operating Instruction
Bit 14, Torque OK/Torque exceeded
When bit 14 = "0", the motor torque is below the limit
selected in F-40 Torque Limiter (Driving) and F-41 Torque
Limiter (Braking). When bit 14 = "1", the limit selected in
F-40 Torque Limiter (Driving) or F-41 Torque Limiter (Braking) is
exceeded.
Bit 15, Timer OK/Timer exceeded
When bit 15 = "0", the timers for the thermal motor
protection and electronic overload protection have not
exceeded 100%.
When bit 15 = "1", one of the timers has exceeded 100%.
