Heatsink OT
Condition: Heatsink temperature too high alarm
Solution:
- Verify the correct operation of the cooling fan.
- Check that the heatsinks are not clogged
12
HeatsinkS OTUT
Condition: Heatsink temperature too high or too low alarm
The temperature has exceeded the upper or lower limit set for the linear temperature transducer.
Solution:
- Verify the correct operation of the cooling fan.
- Check that the heatsinks are not clogged
- Check that the openings for the cabinet cooling air are not blocked.
13
Intakeair OT
Condition: Intake air temperature too high alarm
Solution:
Check correct fan operation
14
Drive overload
Condition: Drive overload alarm.
The overload threshold of the accumulator of the I²t drive thermal image has been exceeded.
Solution: Check that the size of the drive is suitable for the application.
15
Bres overload
Condition: Braking resistor overload alarm.
The current absorbed by the resistor is greater than the rated current. The overload threshold of
the accumulator of the I²t braking resistor thermal image has been exceeded.
Solution:
Increase the Watt value of the braking resistor
16
Opt Bus fault
Condition: Error in the configuration stage or communication error.
XXX0H-X
If the first digit to the left of “
H
” in the alarm sub-code is 0, the error regards a
communication problem.
XXXXH-X
If the first digit to the left of “
H
” in the alarm sub-code is other than 0, the error
regards a configuration problem.
Solution:
For configuration errors, check the configuration of the Bus communication, Bus type,
Baudrate, address, parameter settings.
For communication errors verify wiring, resistance of terminations, interference immunity,
timeout settings.
For further details, please refer to the user guide for the specific bus.
17
Opt 1 IO fault
Condition:
Error in the communication between Regulation and I/O expansion card in slot 1.
Solution:
Check that it has been inserted correctly, see chapter 11.5
18
Opt 2 IO fault
Condition:
Error in the communication between Regulation and I/O expansion card in slot 2.
Solution:
Check that it has been inserted correctly, see chapter 11.5
19
Opt Enc fault
Condition: Error in communications between the regulation board and voltage synchroni-
sation card in slot 2
Solution: Check that they are inserted correctly
20
External fault
Condition: External alarm present.
A digital input has been programmed as an external alarm, but the +24V voltage is not available
on the terminal.
Solution:
Check that the terminal screws are tight
