10.4 Error information of the power section
10.4.1 Fault memory
The fault memory (P080) stores the last 5 error messages (faults t-0 – t-4) of the fre-
quency inverter. The oldest error message is deleted whenever more than 5 error
messages have occurred.
The following information is stored when an error occurs:
• Error which has occurred • Active current
• Status of digital inputs/outputs • Device utilization
• Frequency inverter operating status • DC link voltage
• Frequency inverter status • Operating hours
• Heat sink temperature • Enable hours
• Speed • Parameter set
• Output current • Motor utilization
10.4.2 Switch-off responses
The following switch-off responses occur in the frequency inverter depending of the
error. In all cases, the frequency inverter of the device remains inhibited in error
status.
Immediate stop
The device can no longer decelerate the drive. In the event of an error, the output
stage goes to high-resistance and the brake is applied immediately.
Rapid stop
The drive is decelerated with the stop ramp. The brake is applied when the stop speed
is reached. The output stage goes to high resistance after the brake application time
has elapsed.
Emergency stop
The drive is decelerated with the emergency stop ramp. The brake is applied when the
stop speed is reached. The output stage goes to high resistance after the brake ap-
plication time has elapsed.
10.4.3 Reset
WARNING
Risk of injury and possible damage to property due to automatic restart of the drive
after fault elimination or after a reset.
Fatal or severe injuries and damage to property.
• Disconnect the device from the power supply before rectifying a fault if automatic
restart of the driven machine is not permitted for safety reasons.
• After a reset, make sure that the drive can start up automatically depending on
the setting.
