11.6.8 Error 7: Device heatsink temperature error
11.6.8.1 Error 7-1 (emergency code 4210h)
Cause: Heat sink temperature too high
Suggested steps:
reduce the load and check the conditions of the drive
An overcurrent was
detected.
l
Please check current control settings and step
response.
l
Check the motor's saturation settings
(parameter MOT_LSigDiff). If the error
occurred in high-current range, lower
saturation values manually.
l
If possible, reduce the needed current,
especially in low-frequency range.
l
If possible, lower the switching frequency or
enable automatic frequency selection.
l
Check if the encoder offset is set properly.
l
Consider using an axis module with higher
current rating.
This is possibly a hardware
issue
If other measures fail to solve the problem, please
replace the servo drive.
