(39) PG Parameter (Cn-45)
•The parameter is set in the unit of pulse/revolution. The factory setting is 0.1 P/R.
(40) Pole Number of Motor (Cn-46)
•Cn-45 and Cn-46 must meet the following relationship:
2 * Cn-45 * Cn-02
Cn-46
< 32767
•If not, an error message “Input Error” will be displayed
(41) ASR Proportion Gain 1 (Cn-47)
(42) ASR Integral Gain 1 (Cn-48)
•Set the proportion gain and integral time of the speed control (ASR)
(43) ASR Proportion Gain 2 (Cn-49)
(44) ASR Integral Gain 2 (Cn-50)
•Use these constants to set different proportional gain and integral time settings for
high-speed operation.

These settings of Cn-51 and Cn-52 will limit the ASR range. See Fig. 44 on page 86.
(47)Excessive Speed Deviation Detection Level (Cn-53)
•This parameter set the level of detecting PG speed deviation. The value of Cn-02 is
referred as 100%, the default unit setting is 1%.
(48)Overspeed Detection Level (Cn-54)
•Set this parameter for detecting overspeed. The value of Cn-02 is referred as 100%,
the default unit setting is 1%. Please refer setting of Sn-43 on page 96.
