12 DATA USED FOR POSITIONING CONTROL
12.7 Monitor Data
[Md.28] Axis feedrate
• The speed which is actually output as a command at that time in each axis is stored. (May be different from the actual motor
speed)"0" is stored when the axis is at a stop. (Page 479 [Md.22] Feedrate)
Refresh cycle: Operation cycle
■Reading the monitor value
Refer to the following.
Page 478 [Md.20] Current feed value
• Monitoring is carried out with a hexadecimal.
• Buffer memory address
Refer to the following for the buffer memory address in this area.
Page 390 Monitor data
[Md.29] Speed-position switching control positioning movement amount
• The movement amount for the position control to end after changing to position control with the speed-position switching
control is stored. When the control method is "Reverse run: position/speed", the negative value is stored.
Refresh cycle: Immediate
■Reading the monitor value
Refer to "[Md.28] Axis feedrate".
