16 FULLY CLOSED LOOP SYSTEM
534
16.3 Operation and functions
Explanation
For address increasing direction in the servo motor CCW, it is indicated as "+" and for address
decreasing direction in the servo motor CCW, as "-".
If the fully closed loop system is "Disabled", the Z-phase pass status of the servo motor encoder is
displayed. If the fully closed loop system is "Enabled" or "Semi closed loop control/fully closed loop
control switching", the Z-phase pass status of the load-side encoder is displayed.
Only if the fully closed loop system is "Semi closed loop control/fully closed loop control switching", the
device is displayed.
The state of the semi closed loop control/fully closed loop control switching signal and the inside state
during selection are displayed.
The feedback pulse electronic gears ([Pr. PE04], [Pr. PE05], [Pr. PE34], and [Pr. PE35]) are displayed/
set for servo motor encoder pulses in this parameter.
Page 524 Setting of feedback pulse electronic gear
The band of [Pr. PE08 Fully closed loop dual feedback filter] is displayed/set in this parameter.
The parameter for the fully closed loop control is displayed or set.
Click "Parameter setting" to display the "Fully closed loop control - Basic" window.

1) Fully closed loop function selection ([Pr. PE01])
Select "Always valid" or "Change according to fully closed selection signal" here.
2) Feedback pulse electronic gear ([Pr. PE04], [Pr. PE05], [Pr. PE34], [Pr. PE35])
Set the feedback pulse electronic gear.
3) Load-side encoder cable communication method selection ([Pr. PC26])
Select a load-side encoder cable to be connected to the CN2L connector.
4) Selection of encoder pulse count polarity ([Pr. PC27])
Select a polarity of the load-side encoder information.
5) Selection of A/B/Z-phase input interface encoder Z-phase connection judgment function ([Pr.
PC27])
Select the non-signal detection status for the pulse train signal from the A/B/Z-phase input interface
encoder used as a linear encoder or load-side encoder.
This function is enabled only when you use an A/B/Z-phase input interface encoder.
