Chapter 7 – Troubleshooting

Chapter 7 - Troubleshooting

1 - FAULTS

1.1 - SYSTEM FAULT

If the red

SYS

led is lit when the amplifier is on, the logic board is defective.

- Check that the EPROM firmware memory is correctly plugged on the amplifier.
- Check for the possible presence of any conducting dust that may involve short-circuits on the amplifier logic
board.

1.2 - "BUSY" FAULT

¾

If the BUSY fault is continuously displayed after applying power to the amplifier, the

AUTOTEST

procedure

has failed and the amplifier is not ready for operation. Check that the power voltage is not on before the 24 V
auxiliary supply (see connection diagrams in

Chapter 4, section 1

¾

If the BUSY fault is continuously displayed after the execution of the

AUTO-PHASING

function, the procedure

has failed because of an external cause and the calculated parameters are wrong. Check that the ENABLE
input is actually open. Check that the limit switch inputs are not activ. Then check that the motor is unloaded
and the shaft movement is free during the procedure.

¾

If the BUSY fault is continuously displayed after the execution of the

AUTO-TUNING

function, the procedure

has failed because of an external cause and the calculated parameters are wrong. Check that the

ENABLE

input is actually open. Check that the limit switch inputs are not activated. Then check that the motor is
unloaded and the shaft movement is free during the procedure.

¾

If the BUSY fault is continuously displayed after the execution of the

OFFSET COMPENSATION

function, the

offset is exceeding 0.5 Volt. Check the voltage on the speed command input during the procedure.

1.3 - "EEPROM" FAULT

¾

Check the presence of the EEPROM and check its correct orientation.

¾

If the fault remains, the EEPROM is not correctly initialized (

CHECKSUM

) or is not compatible with the

amplifier software version.

1.4 - "°C MOTOR" FAULT

¾

If the failure occurs when starting the amplifier:

Modify the thermal sensor type (CTP or CTN) by means of the VISUAL DRIVE SETUP software. Make a

fault RESET by means of the VISUAL DRIVE SETUP software. The “°C MOTOR" fault display must go out.

Check the connection between the thermal sensor and the amplifier on the front panel X1 connector.

¾

If the failure occurs during the operation:

Check the motor temperature and look for the reason of this overheating (mechanical shaft overload, duty

cycle too high, motor type to small with regard to the machine cycle…).

1.5 - "UNDERVOLT" FAULT (non stored)

When switching on the auxiliary 24 V

DC

supply, the CD1-a amplifier always displays the UNDERVOLT. fault. The

UNDERVOLT. Led will go out when switching on the power voltage, after a few seconds time delay that
corresponds to the power capacitors soft start. If the fault display remains after switching on the power supply:

Check that the power supply is actually on.
