5. PARAMETERS

5.4.2 Explanation of the modified parameters

(1) Feedback pulse number (parameter No. 6)
This parameter was newly added to the MR-J2S- B. If the peripheral software of the servo system
controller is not compatible with the MR-J2S- B, this parameter setting cannot be changed. When
the servo motor used is the HC-KFS or HC-MFS, the feedback pulse number is 8192 pulses/rev, and
when it is the HC-SFS, HC-RFS or HC-UFS, the feedback pulse number is 16384 pulses/rev.
(2) Auto tuning (parameter No. 8)
The set values of this parameter were newly added to the MR-J2S- B. If the peripheral software of
the servo system controller is not compatible with the MR-J2S- B, the parameter settings are as
indicated below. The auto tuning mode 2 and manual mode 1 cannot be used.
0 0 0
(3) Servo response level (parameter No. 9)
The set values of this parameter were newly added to the MR-J2S- B. In addition, the machine
resonance frequency guidelines corresponding to the set values were changed. If the peripheral
software of the servo system controller is not compatible with the MR-J2S- B, the parameter settings
are as indicated below.
