The Analog Spply Tol Fault
Analog Spply Tol is a non-configurable fault. It indicates that the
voltages from the analog power supply are out of the appropriate
range (13V to 18V). If you receive an Analog Spply Tol fault, you
most likely have a problem with your power supply.
The Absolute Overspd Fault
Absolute Overspd is a non-configurable fault that occurs when the
speed feedback regulator indicates that the speed of the motor is
greater than the maximum values specified in Fwd Speed Limit
(parameter 41) and Rev Speed Limit (parameter 40). You can use
Absolute Overspd (parameter 24) to specify how much faster than the
maximum speeds specified in Fwd Speed Limit and Rev Speed Limit
the drive can go before generating an Absolute Overspd fault.
The Inv Overtemp Pnd and Inv Overtemp Trp Faults
Inv Overtemp Pnd is a configurable fault that is controlled through
bit 1 of Fault Select 2 and Warning Select 2. The drive monitors the
heatsink temperature. If the temperature reaches around 80
°C, you
will get an Inv Overtemp Pnd fault.
Inv Overtemp Trp is a non-configurable fault. You will get an Inv
Overtemp Trp fault if the temperature of the heatsink is not between
-20
°C and 100°C.
For both faults, the cause may be a sensor either open or shorted, a
blocked or inoperative inverter cooling fan, or extended operation of
the drive beyond the current rating.
