6.1 Fault information
6.1.1 Fault memory
The fault memory (P080) stores the last 5 fault messages (faults t-0 – t-4). The oldest
fault message is deleted whenever more than 5 fault messages have occurred. The
following information is stored when a fault occurs:
Fault that has occurred · Status of digital inputs/outputs · Operating state of the in-
verter · Inverter status · Heat sink temperature · Speed · Output current · Active cur-
rent · Unit utilization · DC link voltage · ON hours · Enable hours · Parameter set · Mo-
tor utilization.
6.1.2 Switch-off responses
There are 3 switch-off responses depending on the fault; the inverter remains blocked
during a failure:
Immediate disconnection
The unit can no longer brake the drive; the output stage goes to high resistance in the
event of a fault and the brake is applied immediately (DBØØ "/Brake" = "0").
Rapid stop
The drive is braked with the stop ramp t13/t23. Once the stop speed is reached, the
brake is applied (DBØØ "/Brake" = "0"). The output stage goes to high resistance after
the brake application time has elapsed (P732 / P735).
Emergency stop
The drive is braked with the emergency stop ramp t14/t24. Once the stop speed is
reached, the brake is applied (DBØØ "/Brake" = "0"). The output stage goes to high
resistance after the brake application time has elapsed (P732 / P735).
6.1.3 Reset
A fault message can be acknowledged as follows:
• Switch the supply system off and on again
– Observe a minimum switch-off time of 10 s for the line contactor K11
• Reset via input terminals, i.e. via an appropriately assigned digital input (DIØ1 –
DIØ7 with the basic device, DI1Ø – DI17 with the DIO11B option)
• Manual reset in MOVITOOLS
®
MotionStudio (P840 = "YES").
• Manual reset using the DBG60B.
• Auto reset performs up to 5 device resets with an adjustable restart time.
