(For sizes from 22kW ... and higher). Temperature of the cooling air too high.
Failure of device fan(s).
Cooling opening obstructed.
An unused interrupt has occurred
Switch off device and restart
If you are unsuccessful: probably an internal fault. Contact your service office.
(For sizes from 0.75 to 15 kW). Temperature of the IGBT module too high.
Failure of device fan.
Failure in the IGBT module on power section.
Fast overload current duty cycle.
Internal Overcurrent failure of IGBT power section
Switch off device and restart
If you are unsuccessful, contact your service office.
Overcurrent in the motor circuit
Short-circuit or ground fault at the output of the drive
Current regulator optimized incorrectly
Message appears when switching on the device: drive is engaging a motor that is
running. Auto capture function must be activated.
Switch off device and restart
If you are unsuccessful, contact your service office.
Overvoltage in intermediate circuit due to energy feedback from motor
Lengthen deceleration ramp. If not possible:
Use a BU... braking unit to reduce the feed
Overtemperature of the motor (indicated via thermistor on terminals 78/79)
Cable between thermistor connection on motor and terminals 78 and 79 interrupted.
Overheating of motor:
- Load cycle too extreme
- Ambient temperature at site of motor too high
- Motor has an external fan: fan failed
- Motor does not have an external fan: too large a load at low speeds. The cooling
effect of the fan on the motor shaft is too low for this load cycle. Change cycle
or fit external fan.
Temperature of the Regulation card of the Drive too High.
Ambient temperature too high.
Speed feedback loss
Encoder not connected, or incorrectly connected or not supplied:
Select the Enc 1 speed parameter in the MONITOR\ Measurement \ Speed \ Speed
in rpm menu.
