12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting
■
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 100 for all the axes.
[Pr.17] Torque limit setting value
Set the maximum value of the torque generated by the servomotor in units of %.
The torque limit function limits the torque generated by the servomotor within the set range.
If the torque required for control exceeds the torque limit value, the control is performed with the set torque limit value.
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Setting range
The setting range is 1 to 5000.
■
Default value
The default value is 300 for all the axes.
Limits for the pulse train output type
• A drive unit that can issue a torque limit command with analog voltage is required.
• The D/A converter module and the wiring between the D/A converter module and drive unit are required.
• The set value in [Pr.17] Torque limit setting value is set for [Md.35] Torque limit stored value in the buffer
memory. Transfer the value set in [Md.35] Torque limit stored value to the D/A converter module with
programs.
