When using the MacTalk PC-program any error or warning is shown in 'Status' field at
the main tab.
General error and warning monitoring area
In this area actual values for the motor operation is
tripped if the the monitored value 'Motor load (mean)'
gets above 99%. Therefore make sure that the value
during normal operation have a proper margin to 100%.
Warnings and status information are presented here

The calculated accumulated load of the motor and electronics
above limit. The actual level of losses can be observed in the
'Motor load (mean)' field (see the screen dump above).
The motor has been loaded above maximum continuous
torque rating for too long time, causing a critical internal tem-
perature.
- Reduce average motor load.
- Reduce the speed and/or acceleration.
- Adjust servo filter to a stable behaviour during any event.
- Make sure that the supply voltage is at the specified level.
- Reset the motor, clear the error bit(s) in register 35 or cycle
the power.
