8. SPECIAL ADJUSTMENT FUNCTIONS
(4) Gain changing selection (parameter No. 65)
Used to set the gain changing condition. Choose the changing condition in the first digit. If you set "1"
here, you can use the gain changing (CDP) external input signal for gain changing. The gain changing
(CDP) can be assigned to the pins using parameters No. 43 to 48.
Parameter No. 65
Gain changing selection
Gains are changed in accordance with the settings of
parameters No. 61 to 64 under any of the following conditions:
0: Invalid
1: Gain changing (CDP) input is ON
2: Command frequency is equal to higher than parameter No. 66 setting
3: Droop pulse value is equal to higher than parameter No. 66 setting
4: Servo motor speed is equal to higher than parameter No. 66 setting
(5) Gain changing condition (parameter No. 66)
When you selected "command frequency", "droop pulses" or "servo motor speed" in gain changing
selection (parameter No.65), set the gain changing level.
The setting unit is as follows.
Gain changing condition Unit
Command frequency kpps
Droop pulses pulse
Servo motor speed r/min
(6) Gain changing time constant (parameter No. 67)
You can set the primary delay filter to each gain at gain changing. This parameter is used to suppress
shock given to the machine if the gain difference is large at gain changing, for example.
