"EEPROM"
FAULT
Check for the presence of the EEPROM and check its correct orientation and mounting.
If the fault remains, the EEPROM is not correctly initialized (CHECKSUM error) or is not compatible with the
amplifier software. In this case, if the EEPROM fault is reset and if then the
Save parameters to EEPROM
procedure is executed, the EEPROM is automatically reinitialized with the amplifier default parameters.
2.3
-
"°C
MOTOR"
FAULT
If the fault occurs when starting the amplifier:
- Check the configuration of the
MN
and
OP
jumpers with regard to the type of thermal sensor used in the
motor.
- Check the connection between thermal sensor and amplifier on the front panel connector X1.
If the fault occurs during the operation:
- Check the motor temperature value and look for the reason of the motor overheating (mechanical
overload, duty cycle too high, ...)
2.4
-
"UNDERVOLT."
FAULT
If the fault occurs when starting the amplifier:
- Check that the power supply is on.
If the fault occurs during the operation:
- Check that the power supply connections are correct
- Check that the power supply voltage value is correct

-
"°C
AMPLIFIER"
FAULT
Check that the fan and the heatsink configurations are correct with regard of the required rated current (
see
current table, Chapter 2, section 1
).
Remark : This fault is only valid on amplifiers with current ratings 220/70 and 220/100.
2.6
-
"POWER
STAGE"
FAULT
If the fault occurs when starting the amplifier:
- Check the DC bus voltage and the terminal voltage of the power transformer secundary :
For the 220VAC version of the amplifier DC bus < 370 VDC and V secundary < 260 VAC
For the 400VAC version of the amplifier DC bus < 800 VDC and V secundary < 480 VAC
If the fault occurs during the operation:
- Check the braking system operation during the deceleration phases is correct,
- Check the sizing of the braking resistor with regard to the deceleration phases.
- Check for no short-circuit in the motor wiring and at the motor terminals.
- For amplifiers with 220/04 to 220/60 current ratings and 400 VAC range, check that the fan and the
heatsink configuration is correct with regard to the required rated current (
see current table, Chapter 2
,
section 1
).
2.7
-
"HES"
FAULT
For the "incremental encoder & HES" configuration:
Check that the HES are correctly wired on the amplifier X1 connector (with 60° type HES you must check the
different wiring combinations to found the right wiring order).
Check that the commutation signal jumpers COM are correctly set according to the HES type.
Check for the correct HES supply voltage value.
Check for the correct
Motor encoder resolution
parameter value.
Check that the HES-amplifier-motor ground connections and shield answer the requirements of
chapter 4
.
For the "Absolute single turn Sin/Cos encoder" configuration:
