There is no data available
(Trip history, PID feedback data)
The auto tuning process has successfully completed.
This function detects a phase loss on the input AC source. Detection is
performed by monitoring the voltage ripple on the DC bus. This voltage
ripple causes heat to the Bus Capacitors which shortens their life.
When the temperature in the main circuit exceeds a pre-defined level the
VFD faults. Usually caused by a cooling fan failure or by a clogged
heatsink or filter.
This condition occurs when the leakage current to ground exceeds a pre-
defined level. Fault is only detected when the VFD is running.
When the current rating of the VFD is exceeded, the internal thermal
overload protection circuit is activated to protect the output transistors.
The time it takes the VFD to trip is dependent upon the carrier frequency,
the load, the ambient temperature and the power rating.
When the BRD exceeds the duty cycle of the braking resistor this fault will
occur. The circuit is designed to calculate and protect the braking resistor
from thermally overheating.
The OVS output frequency is higher than maximum OVS output frequency
during the setting time when the OVS function is enabled
The Fan fault is indicated when the fan is not rotated
The output current of the drive is greater than the detection level set for
this feature when it is enabled
The output current of the drive is less than the detection level set for this
feature when it is enabled.
ProfibusDP optional card only. Host disconnection, or invalid host setting
cause this error
DeviceNet optional card only. Communication cable power loss,
disconnect to host, or invalid host setting cause this error
