2.6 Error Handling
2.6.4 Error message ’Follow error’
2.6.5 Error message ’Function error’
Message no. / Message
2 / ’Follow error’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition The actual difference between the actual motor position and the
intended position is higher than the value specified in the ’Max-
imum follow error’ field in MacTalk.
Possible cause of this error The motor has been applied too high a load or the ’maximum fol-
low error’ value have been set at an unrealistic low value in re-
gards to the actual hardness of the servo filter.
Solutions to avoid error - Increase the ’’Maximum follow error’ value.
- Adjust the servo filter hardness to a more aggressive value.
- Make sure that the torque setting is not limiting the motor
movement.
- Set the ’Maximum follow error’ to 0 (default) which will disa-
ble the detection of this error type.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
Error bit / Firmware name Bit 1 / ’FLW_ERR’
Message no. / Message
3 / ’Function error’
Type / Motor action
Unrecoverable error / Motor is set in passive mode.
Error condition
If the actual load torque of the motor gets higher than the spec-
ified torque setting permits it will cause the motor to slip away
from where it is supposed to be. If the number of motor counts
missing in this situation gets higher than the value specified in
the ’Maximum function error’ field in MacTalk it will trigger the
’function error’. If the actual motor torque never reaches the val-
ue specified in the ’torque’ field this error will never be triggered.
The above condition is valid when the motor is operated in Po-
sition mode, Biposition mode, or Analogue to position mode.
Possible cause of this error
The motor has been applied too high a load or the ’maximum
function error’ value have been set at an unrealistic low value in
regards to the ’torque’ setting.
Solutions to avoid error
- Increase the ’Maximum follow error’ value.
- Adjust the servo filter hardness to a more aggressive value.
- Make sure that the torque setting is not limiting the motor
movement.
- Set the ’Maximum function error’ to 0 (default) which will dis-
able the detection of this error type.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle the
power.
