12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
[Pr.21] Current feed value during speed control
Specify whether to enable or disable the update of [Md.20] Current feed value while operations are performed under the
speed control (including the speed control of speed-position switching control and position-speed switching control).
• When the speed control is performed over two to four axes, the selection between enabling and disabling the update of
[Md.20] Current feed value depends on how the reference axis is set.
• Set 1: Current feed value is updated to perform the speed-position switching control (ABS mode).
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Default value
The default value is 0: Current feed value is not updated for all the axes.
[Pr.22] Input signal logic selection
Set the logic of each input signal according to the external device.
The following table shows the assignment of each input signal. Set a value for the target bit.
• A mismatch in the signal logic will disable normal operation. Be careful of this when the setting is changed from the initial
value.
• Set the logic selection (b8) of the manual pulse generator input for the axis 1. (Setting for any of the axis 2 to 4 is invalid.)
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Default value
Each input signal of all the axes is set to 0: Negative logic.
Current feed value during
speed control Setting value Description
Current feed value is not updated 0 The current feed value does not change. (The current feed value during speed control start is
maintained.)
Current feed value is updated 1 The current feed value is updated. (The current feed value changes from the initial value.)
Current feed value is cleared to zero 2 The current feed is set to 0 and does not change from 0 while the speed control is performed.
