[Md.1008] Execute program No. (R: D32012+48n/Q: D12+20n)
• This register stores the starting program No. at the servo program starting.
• The following value is stored for the following items.
Item
JOG operation
Manual pulse generator operation
Speed control
Torque control
Continuous operation to torque control
Power supply on
Current value change execution by the Motion dedicated PLC instruction (CHGA instruction)
Direct positioning start by the Motion dedicated PLC instruction (SVSTD instruction)
Machine program operation start by the Motion dedicated PLC instruction (MCNST instruction)
Machine program operation start by the Motion SFC program (MCNST instruction)
Machine JOG operation
Pressure control
Advanced synchronous control
• When the following control is being executed using MT Developer2 in the test mode, the following value is stored in this
register.

Home position return
During G-code control, "[Md.1008] Execute program No. (R: D32012+48n/Q: D12+20n)" is not updated.
[Md.25] M-code (R: D32013+48n/Q: D13+20n)
• This register stores the M-code
program, the value "0" is stored.
• It does not change except positioning start using the servo program.
• The value "0" is stored at leading edge of "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)".
• During machine program operation, the M-code set in positioning data is stored at positioning start completion and at the
start of each point.
*1 Refer to the M-code output function for M-codes. (Page 425 M-code Output Function)
[Md.35] Torque limit value (R: D32014+48n/Q: D14+20n)
This device stores the positive direction torque limit value to command the servo (unit: 0.1[%]).
The default value "300.0[%]" is stored when communication with the servo amplifier is established.
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" in [Motion Control Parameter]  [Axis Setting Parameter] 
"Expansion Parameter". (Page 192 Expansion Parameters)
