☆ When cargo tends to momentarily drop down in a raising/lowering application (normal rotation/reverse rotation
command), the settings described below can be configured in order to improve operation.
Improvement Method
Then gradually reduced from the default setting of
f345 "Braking Release Time", adopt a value that is cargo down
the behavior steps.
Response also can be further improved by raising the values of
f460 "Speed loop proportional gain" and f930
"Position loop gain". Refer to "6.16 Control gain adjustment function" for details about these functions.
6.13 PID control
: PID control waiting time
: PID control
: Proportional gain
: Integral gain
: Differential gain
: PID forward/reverse characteristics selection
Function
Using feedback signals (4 to 20mA, 0 to 5 V, 0 to 10V) from a detector, process control can be
exercised, for example, to keep the airflow, amount of flow or pressure constant.
Or, it is also possible to always set 0 for integral and differential at terminal input.
