I.t-trP
04 Motor overload. The thermal protection mechanism has tripped as a result of
the device being run above the rated motor current set with P1-08 longer than
a specific time.
• Check to make sure that the motor data was entered correctly in P1-08.
• Check the motor's connection configuration (e. g., start/delta).
• Make sure that the motor is not being mechanically blocked and that there
are no additional loads on the motor.
O.Volt
06 Overvoltage in DC link
The DC-Link Voltage value can be viewed using parameter P0-20.
P0-36 contains an error register with the last values before the unit was
switched off (scan time: 256 ms).
• Check to make sure that the supply voltage falls within the range for which
the variable frequency drive is sized.
V.Volt
07 Undervoltage in DC link
Note:
Generally, this message will appear when the supply voltage is switched off
on the device and the DC link voltage dies away.
In this case, there is no fault.
If the message appears during operation:
• Check whether the power supply voltage is too low.
• Check all components/devices in the variable frequency drive's feeder
circuit (circuit-breaker, contactor, choke, etc.) to make sure they are
connected properly and have an adequate contact resistance.
