Gain Swtich: Sequence Input Signal (Reference Value 17) - Fuji Electric ALPHA7 User Manual

Gain swtich: Sequence input signal (Reference value 17)

To switch the gain (response capability) of the servo system.
 Function
When PA1_61 (gain changing factor) is set at "3" (external switch: CONT signal), the CONT signal
assigned to this function switches the gain of the servo system.
The control gain parameters that are enabled with the gain switch are listed in the table below.
Use the function to change the gain of the servo system between the going path and returning
path in a reciprocal motion or similar.

 Parameter setting
To assign the gain switch to IQ area (sequence input terminal), specify the corresponding value
("17") to the input terminal function setting parameter.
This signal is handled to be always turned off if it is not assigned to the sequence input terminal.
