Interrupt error

An unused interrupt has occurred

Switch off the drive and restart

If still unsuccessful, the fault is probably internal. Contact your service office

Module overtemp

(For sizes from 1 Hp to 20 Hp). Temperature of the IGBT module is too high

Failure of drive fan

Failure in the IGBT module in the power section.

Fast overload current duty cycle.

Output stages

Internal Overcurrent failure of IGBT power section

Switch off drive and restart

If unsuccessful, contact your service office

Overcurrent

Overcurrent in the motor circuit

Short-circuit or ground fault at the output of the drive

Current regulator tuned incorrectly

Message appears when switching on the drive: drive is connecting to a motor
that is running. Auto capture function must be activated

Switch off drive and restart

If unsuccessful, contact your service office

Overvoltage

Overvoltage on the DC Bus due to energy regenerated from motor

Lengthen deceleration ramp. If not possible:

Use a BU... braking unit to increase the energy absorption capability

Overtemp Motor

Overtemperature of the motor (indicated via thermistor on terminals 78/79)

Cable between thermistor in motor and terminals 78 and 79 interrupted

Overheating of motor:

- Load cycle too extreme

- Ambient temperature at motor location too high

- Motor has an external blower and it has failed

- Motor does not have an external blower: load too large at low speeds. The cooling effect

of the fan on the motor shaft is inadequate for this load cycle. Change cycle or install an
external blower

Regulation ot

Temperature of the drive regulator card is too high

Ambient temperature too high

Speed fbk loss

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.

- With the drive disabled, manually turn the motor clockwise (viewed from the front of the

shaft). The value indicated must be positive.

- If the indicated value does not change or random values are shown, check the power

supply and the cabling of the encoder.

- If the indicated value is negative, reverse the encoder connections. Exchange channel

A+ and A- or B+ and B-
