MDR61B1600/2500 error information
Error memory
The error memory (P080) stores the last five error messages (errors t-0 ... t-4). The old-
est error message is deleted whenever more than 5 error messages have occurred. The
following information is stored when a malfunction occurs:
Error that has occurred · Status of binary inputs/outputs · Operating status of the inverter
· Inverter status · Heat sink temperature · Output current · Active current · Unit utilization
· DC link voltage · ON hours · Enable hours.
Switch-off
responses
There are 3 switch-off responses depending on the error; the inverter remains blocked
during the error status:
Immediate discon-
nection
The unit can no longer brake the drive; the output stage goes to high resistance in the
event of an error and the brake is applied immediately (DBØØ "/Brake" = "0").
Reset
An error message can be acknowledged by:
• DC 24 V power supply switch-off
Recommendation: Observe a minimum switch-off time of 10 s for the line contactor
K11.
• Reset via input terminals DIØ2, i.e. via binary input
• Manual reset in SHELL (P840 = “YES” or [Parameter] / [Manual reset]).
• Manual reset using the DBG60B.
• Auto reset performs up to 5 unit resets with an adjustable restart time.
WARNING
Risk of crushing if the motor starts up automatically after an auto reset.
Severe or fatal injuries.
• Do not use auto reset with drives where an automatic restart represents a danger
to people or units.
• Perform a manual reset.
