Selecting a fully closed loop system
With the settings of [Pr. PA01], [Pr. PE01], and the controller control command, a control method can be selected as described
in the following table.
*1 Can be supported when the load-side encoder is an absolute position encoder.
■
Selecting an operation mode
Select an operation mode.
• [Pr. PA01.4 Fully closed loop operation mode selection]
■
Selecting semi closed/fully closed loop control
Select semi closed/fully closed loop control.
• [Pr. PE01.0 Fully closed loop function selection]
0: Always enabled
1: Switching by fully closed loop selection command from the controller and by input device CLD (fully closed loop selection)
*2
*1 This is always off if the CLD (fully closed loop selection) is not assigned to an input device.
*2 If "1" is set in [Pr. PE01.0] while [Pr. PA03.0 Absolute position detection system selection] has been set to "1" (Enabled), [AL. 037.2
Parameter combination error] occurs.
This setting is enabled when "1" (fully closed loop control mode) is selected in [Pr. PA01.5 Fully closed loop operation mode
selection].
