Issue Number: 2
HF18
Data processing error: Internal flash memory has failed
The HF18 trip indicates that the internal flash memory has failed when writing option module parameter data. The reason for
the trip can be identified by the sub-trip number.
Recommended actions:
•
Hardware fault - Contact the supplier of the drive
HF19
Data processing error: CRC check on the firmware has failed
HF19 trip indicates that the CRC check on the drive firmware has failed.
Recommended actions:
•
Re-program the drive
•
Hardware fault - Contact the supplier of the drive
Hot Rect/Brake
Hot rectifier/brake
250
Over-temperature detected on input rectifier or braking IGBT.
I cal. range
Current calibration range
231
Current calibration range error.
I/O Overload
Digital output overload
26
The
I/O Overload
trip indicates that the total current drawn from 24 V user supply or from the digital output has exceeded the
limit. A trip is initiated if the following condition is met:
•
Maximum output current from one digital output is 100 mA.
Recommended actions:
•
Check total loads on digital outputs
•
Check control wiring is correct
•
Check output wiring is undamaged
Keypad Mode
Keypad has been removed when the drive is receiving the reference from the keypad
34
The
Keypad Mode
trip indicates that the drive is in keypad mode [
Reference Selector
(01.014) = 4 or 6] and the keypad has
been removed or disconnected from the drive.
Recommended actions:
•
Re-install keypad and reset
•
Change
Reference Selector
(01.014) to select the reference from another source
LF Power Comms
Communication has been lost / errors detected between power, control and rectifier modules
90
This trip is initiated if there is no communications between power, control or the rectifier module or if excessive
communication errors have been detected. The reason for the trip can be identified by the sub-trip number.
Recommended actions:
•
Hardware fault - contact the supplier of the drive.
Motor Too Hot
Output current overload timed out (I
2
t)
20
The
Motor Too Hot
trip indicates a motor thermal overload based on the output current (Pr
05.007
) and motor thermal time
constant (Pr
04.015
). Pr
04.019
displays the motor temperature as a percentage of the maximum value. The drive will trip
on
It.AC
when Pr
04.019
gets to 100 %.
Recommended actions:
•
Ensure the load is not jammed / sticking
•
Check the load on the motor has not changed
•
Tune the motor rated speed parameter (Pr
5.008
) (RFC-A mode only)
•
Ensure the motor rated current is not zero
Sub-trip
Reason
1
Option module initialization timed out
2
Programming error while writing menu in flash
3
Erase flash block containing setup menus failed
4
Erase flash block containing application menus failed
5
Incorrect setup menu CRC contained in flash
6
Incorrect application menu CRC contained in flash
