Instruction Manual
1. Absolute System
Encoder Alarms
No. Name Description of Symptom
0 Speed error
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-specified
temperature.
7
Battery voltage drop
warning
The battery voltage
(*1)
dropped below the user-specified 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
