7.2.15
Error message ’Closed loop’.
7.2.16
Error message ’External memory’
7.2.17
Error message ’Single turn encoder error’
Message no. / Message
12 / ’Closed loop’
Type / Motor action
Unrecoverable error / Motor is set in Passive mode.
Error condition
The encoder and motor is misaligned.
Possible cause of this error The motor has been updated to a newer firmware where a
new calibration is required for closed loop operation.
Solutions to avoid error
The error only occurs when activating the closed loop. If
closed loop is not needed, then just deactivate it and save
the setting by using “Save in Flash”.
How to return to normal
operation
The motor must be calibrated. This is done by following
procedure:
1. Disconnect any load from the motor shaft.
2. Write 383 to register 24.
3. Wait ~60 seconds for the calibration to finish.
4. When the motor stands still and register 51 (P2) reads 7,
then the motor can be reset by writing 267 to register 24
or simply by cycling the power (CVI).
5. Now the motor should run in closed loop.

Error bit / Firmware name
Bit 12
Message no. / Message
13 / ’External memory’
Type / Motor action
Unrecoverable error / Motor is set in Passive mode.
Error condition
The controller has build in memory for the ”Event log”.
Possible cause of this error The memory self test has failed because of faulty hardware inside
the motor.
Solutions to avoid error
Return the motor for service.
How to return to normal
operation
•
This error will only be set during startup and can be cleared af-
terwards. Then the motor operation will be the same, but the
“Event log” will not work.
•
Clear the error bit(s) in register 35.
Error bit / Firmware name

Message no. / Message
14 / ’Singleturn encoder error’
Type / Motor action
Unrecoverable error / Motor is set in Passive mode.
Error condition
The absolute single turn encoder (H2/H4) has failed.
Possible cause of this error
•
Wrong setup.
•
The distance between the internal magnet and the internal en-
coder sensor is outside the limits caused by too high force at the
motor shaft in forward or backward direction.
Solutions to avoid error
•
Take care when changing settings in Internal_Encoder_Setup
(register 175).
•
Do not expose the shaft or the motor for mechanical shocks.
How to return to normal
operation
•
If the error appeared after changing some settings, please try to
“Load factory defaults” in MacTalk.
•
Cycle the power to the motor.
