MOTOR ANGULAR POSITION SYNCHRONIZATION PROCEDURE
If the motor has been disassembled, or if the E30 error code appears, the following steps are required:
1. Plug the tool in and allow it to go through its boot up sequence; you will see “000”, then the code for the
electronics board version, and nally the diameter setting.
2. DO NOT press the “ON” button. Instead, press, and hold down, both the “UP” and “DOWN” buttons
simultaneously until you see “P0” and then “P1”. The motor will start spinning.
3. You can now release the “UP” and “DOWN” buttons. “P1” will continue to be displayed and the motor will
spin for a short time.
4. (If you see “P2” displayed, it means the synchronization was unsuccessful, so repeat steps 1-3.)
5. If you see “P3” displayed, press, and hold down, both the “UP” and “DOWN” buttons simultaneously until
you see the diameter setting displayed as normal. Synchronization is now complete.
E07 Angle sensor error Unplug / re-plug If problem persists, bring
to service center to have
sensor checked
E08 Motor temperature too high Automatically clears when the
temperature returns to normal
Keep cooling water owing
E11 Current leakage detected Unplug / re-plug If problem persists, bring to
service center
E16 Temperature sensor open circuit Replace Sensor (service center)
E17 Temperature sensor short circuit Replace Sensor (service center)
E30 Motor angular position not
synchronized
Automatically clears after
motor synch positioning
(service center)
888 Failed communication between the
information screen and controller
Automatically clears when it
receives controller signal
If problem persists, bring to
service center
