Trip
OV DC bus voltage has exceeded the peak level or maximum continuous level for 15 seconds
The OV trip indicates that the DC bus voltage has exceeded the VM_DC_VOLTAGE[MAX] or
VM_DC_VOLTAGE_SET[MAX] for 15 s. The trip threshold varies depending on voltage rating of the drive as shown below.

Recommended actions:
• Increase deceleration ramp (Pr 04)
• Decrease the braking resistor value (staying above the minimum value)
• Check nominal AC supply level
• Check for supply disturbances which could cause the DC bus to rise
• Check motor insulation using an insulation tester
P.dAt Power system configuration data error
The P.dAt trip indicates that there is an error in the configuration data stored in the power system. This trip can be
generated from either the drive control system or from the power system. The trip is related to the table uploaded from the
power system at power-up.

01 No data was obtained from the power board.
02 There is no data table.
The power system data table is bigger than the space available in
03
the control pod to store it.
04 The size of the table given in the table is incorrect.
05 Table CRC error.
The version number of the generator software that produced the
06
table is too low.
07 The power data table failed to be stored in the power board.
The power data table used internally by the power module has an
00
error.
The power data table that is uploaded to the control system on
01
power up has an error.
The power data table used internally by the power module does
02
not match the hardware identification of the power module.
