Unidrive M100 User Guide 131
Issue Number: 1
OV DC bus voltage has exceeded the peak level or maximum continuous level for 15 seconds
2
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.
Sub-trip Identification
Recommended actions:
• Increase deceleration ramp (Pr 00.004)
• 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 a insulation tester
OV.Fr Output frequency has exceeded the maximum frequency threshold
222 The OV.Fr trip indicates that the output frequency has exceeded 560 Hz for more than 100 ms.
P. dA t Power system configuration data error
220
The P. dA t trip indicates that there is an error in the configuration data stored in the power system.
Recommended actions:
• Hardware fault – Contact the supplier of the drive
PAd Keypad has been removed when the drive is receiving the reference from the keypad
34
The PAd trip indicates that the drive is in keypad mode [Reference Selector (01.014) = 4 or 6] and the keypad has been
removed or disconnected from the drive.
Recommended actions:
• Re-install keypad and reset
• Change Reference Selector (01.014) to select the reference from another source
