2.7 Error messages and error handling
2.7.16 Error message ’Internal Encoder error’ (only MAC400 to MAC4500)
2.7.17 Error message ’Invalid Filter settings’ (only MAC400 to MAC4500)
2.7.18 Error mess. ’Control voltage unstable’ (only MAC400 to MAC4500)
Message no. / Message
16 / ’Internal Encoder error’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition A malfunction in the internal encoder has been detected.
Possible cause of this error - The encoder disc is broken because the motor have been ex-
posed to mechanical shock. Typical the shaft have been hit
very hard during mounting of the motor.
Solutions to avoid error - Do not expose the shaft or the motor for mechanical shocks.
How to return to normal
operation
Return the motor for service.
Error bit / Firmware name Bit 15 / ’INDEX_ERR’
Message no. / Message
17 / ’Invalid Filter settings’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition The servo filter settings are not within valid ranges.
Possible cause of this error - The setup file used has been corrupted.
- The setup file used is an old type not compatible with the ac-
tual motor version.
Solutions to avoid error - Select a new filter or contact your JVL.
How to return to normal
operation
- Correct the servo filter setting.
See also Servo filter adjustment, page 49.
- Cycle the 24VDC power.
Error bit / Firmware name Bit 16 / ’OLD_FILTER’
Message no. / Message
18 / ’Control voltage unstable’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition The control voltage (24VDC at the P+ and P- terminals) has
been unstable and detected outside the specified voltage range
for a too long time.
Possible cause of this error - The control voltage has been detected outside the nominal
voltage range.
- The voltage has been applied too slowly with variations.
Solutions to avoid error - Make sure that the voltage is stable in the specified voltage
interval.
- Make sure that the voltage is applied in less than 500mS.
How to return to normal
operation
- Cycle the 24VDC power. A reset will not clear the error.
