4.8 Procedure of battery exchange
1) The power supply of FX
-20GM is turned off.
2N
2) Remove side cover from the FX
-20GM.

The absolute position detection is possible with MR-J2 and the MR-H type
servo motor with the ABS detection function.
Operation system: FWD (manual forwarding ), RVS (manual reversal)
ZRN (machine zero return), START (automatic start), STOP ,
Manual pulse generator (2kHz max), Single-step operation input
(Depends upon the parameter setting).
Mechanical system: DOG (near-point signal),
LSF (forward rotation limit), LSR (reverse rotation limit),
Interrupt: 4 points
Servo system: SVRDY (servo ready), SVEND (servo end),
