12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
[Pr.3] Movement amount per rotation (32 bits) (Al)
Set the distance of machine movement (movement amount) per rotation of the motor shaft with 32 bits. When [Pr.62]
Electronic gear selection is set to 1: 32 bits, this area is valid. When the movement amount per rotation of the motor shaft
exceeds the setting range of [Pr.3] Movement amount per rotation (16 bits) in the system used, use this area.
When the movement amount per rotation is set with this area, the adjustment with [Pr.4] Unit magnification is unavailable.
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
*1 When this buffer memory area is set with programs, a calculation is performed in the RD75 to convert a setting value to the value in
each unit. For setting this buffer memory area, take the value after the unit conversion into consideration.
■
Default value
The default value is 20000 for all the axes.
