WARNING & FAULT MESSAGES
SCREEN DESCRIPTION
NTC. The drive uses a NTC thermal sensor to detect temperature
increases within the supply system. When this message is
displayed, the thermal sensor cable may have been cut. (The drive
will continue running).
Overcurrent. The drive trips when the output current exceeds the
200% of the rated current value.
Overvoltage. The drive trips if the DC voltage within bus exceeds
the value established. This value has been established in the
internal configuration during the deceleration process or when the
motor regenerative energy return to the drive is excessive for the
capacitors which compose the DC bus. This fault can also be
caused due to a transitory overvoltage within the supply system.
External Trip. This function can be used whenever the user needs
to cut the output by the use of an external trip signal. The open
/closed contact use will depend on the configuration within the digital
inputs (In.65-
In.71) configured as 4 ‘EXTERNAL TRIP’. Th e drive
cuts the motor output protecting it from the controlled situation within
the terminal.
Short ARM. The drive trips when a short-circuit occurs in the IGBT
or in the output power.
Overheat. The drive trips if overheated caused by a damaged
cooling fan or by the presence of any strange substance within the
cooling system.
Fan trip. An anomaly detecting within the cooling fan. The
protection will be enabled if parameter Pr.79 is set as 0 ‘TRIP’.
Param_Wr_Err. A problem has been detected during the writing of
a parameter by keypad.
Pipe Fill Flt . An error has been detected which makes the PID
feedback be always under the established value. Possible pipe
breakdown.
External Brake. Drive trips when the braking unit reaches a
dangerous temperature.
