20mSec.
(b)Detailed description of absolute position data transmission timing
After the ABSM is turned on, the ABS servo turn-on timeout will occur if the SON is not turned
on within 1 second, but the transmission will not be impacted. If you want to clear the ABS servo
on warning, you can just turn the SON on. The detailed timing diagram is as follows:
(1)
The PLC turns on ABSM and SON.
(2)
When entering the ABS transmission mode, ABST (data ready) is ON after the drive
calculates the absolute position,
(3)
After PLC confirms that ABST is turned on, ABSR (data request) will be ON.
(4)
After confirming that ABSR is turned on, the servo will output the ABS data (2bit) and
turn off ABST.
