Monitoring parameters
Communication error times
Synchronization frame receive error times
(overtime or data error)
Data frame receive error times (overtime
or data error)
UART module error reasons:
1. RS485 noise is too large
2. CPU hasn’t read offset register data in
time caused the data damaged.
Communication overtime times
If the servo continuous communication error
period ≥P7-06, U0-68 +1, servo XNet state
switches to “initial state”, the priority of
UART decreases, wait the synchronization
frame, servo will not alarm right now.
5-10. Absolute encoder servo drive
Absolute encoder present
position feedback
Read double word address 0x1039(hex), it is present
encoder position, with negative and positive pulses.
Absolute encoder clear circles
Write 1 in address 0x2106(hex) can clear the
circles(effective when servo is in bb state, write 0 in
0x2106 after clearing)
Absolute encoder servo no need origin reset after power on again.
