3 POSITIONING DEDICATED SIGNALS
(9) Execute program No. storage register (D12+20n)
(a) This register stores the starting program No. at the servo program starting.
(b) The following value is stored in the JOG operation and manual pulse
generator operation.
1) JOG operation ............................................................. FFFFh
2) Manual pulse generator operation ............................. FFFEh
3) Speed control
4) Torque control
5) Continuous operation to torque control
6) Power supply on ......................................................... FF00h
7) Current value change execution
by the Motion dedicated instruction ........................... FFE0h
8) Advanced synchronous control
(c) When the following control is being executed using MT Developer2 in the
test mode, FFFDh is stored in this register.
• Home position return
(10) M-code storage register (D13+20n) ....................... Monitor device
(a) This register stores the M-code
the positioning start.
If M-code is not set in the servo program, the value "0" is stored.
(b) It does not change except positioning start using the servo program.
(c) The value "0" is stored at leading edge of PLC ready flag (M2000).
REMARK
(Note): Refer to the following sections for M-codes and reading M-codes.
• M-code ......................... Section 7.1
• Reading M-code ........... APPENDIX 2.1
(11) Torque limit value storage register (D14+20n) ....... Monitor device
(a) This register stores the positive direction torque limit value to command the
servo amplifier (unit: [%]).
The default value "300[%]" is stored at the power supply of servo amplifier
ON.
(b) To monitor the positive/negative direction torque limit value, set "positive
direction torque limit value monitor device" and "negative direction torque
limit value monitor device" with the expansion parameter (Refer to Section
4.4). QDS
