Multi-turn sensor error occurred during backup, or speed error
occurred upon the control power on.
1
Angle sensor output
Amplitude error
Abnormal amplitude of Angle sensor output amplitude.
2
Multi-turn ABS sensor
communication error
Could not obtain multi-turn data during Initialisation after power up.
3 Position error
The single-turn sensor value and multi-turn sensor value do not agree
because of faulty sensor; the encoder position data is unreliable.
4 Voltage drop error
Relevant only to absolute encoders.
The supply voltage fell below the rated voltage range upon the control
power OFF.
5 EEPROM error
The saved data in EEPROM is corrupted.
6 Overheat warning
The temperature of the encoder board exceeded the user-specied
temperature.
7
Battery voltage drop
warning
The battery voltage
(*1)
dropped below the user-specied value.
*) The battery voltage is checked at the time of power turning on and every hour afterwards.
The user-specified voltage is not displayed in Digitax SF Connect.
1. Click on the Auxiliary Functions Tab.
2.Check alarms that are occurring.
Use Digitax SF Connect to check alarms from the encoder. In case of alarm numbers 18, 20, or 21, you can check
the details under the Auxiliary Functions tab in Digitax SF Connect.
These alarms cannot be cleared by Alarm Reset or cycle the control power. To reset alarms, execute ENCODER
CLEAR, and then cycle the control power.
If cycling power does not solve the problem, please contact the supplier
