14. ABSOLUTE POSITION DETECTION SYSTEM
Note 1. For the dog type home position return. Need not be connected for the data set type home position return.
2. For the dog type home position return, connect a QD75 deviation counter clearing signal cable. For the data set type home
position return, connect a cable to the output module of the programmable PC or PLC...etc.
3. This circuit is provided for your reference.
4. The electromagnetic brake output should be controlled via a relay connected to the programmable PC or PLC...etc output.
5. Refer to section 3.8.2 (3)(b) and Type QD75P/QD75D Positioning Module User’s Manual when connecting to QD75P.
(2) Sequence program example
(a) Conditions
The ABS data is transmitted using the leading edge of the servo-on switch as a trigger.
1) When the servo-on switch and power supply GND are shorted, the ABS data is transmitted at power-
on of the driver or on the leading edge of the RUN signal after a PC reset operation (PC-RESET).
The ABS data is also transmitted when an alarm is reset or when an emergency stop is reset.
2) An ABS checksum error is caused (Y3AON) if checksum inconsistency is found in transferred data.
3) The following time periods are measured. If the ON/OFF state does not change within the specified
time, the ABS communication error occurs change within the specified time, the ABS communication
error occurs (Y3A ON).
ON period of ABS transfer mode (Y31)
ON period of ABS request (Y32)
OFF period of reading to send ABS data (X22)
