Adjusting Frequency Reference Using Pulse Train Inputs - YASKAWA CIMR-F7A Instruction Manual

Adjusting Frequency Reference Using Pulse Train Inputs

The frequency reference can be adjusted when b1-01 (Reference Selection) is set to 4 (Pulse Train Input). Set
the pulse frequency in constant H6-02 to 100% reference, and then adjust the gain and bias accordingly using
H6-03 and H6-04.

2: PID target value
Set the number of pulses in
hertz, taking the reference to be
100%.
Set the input gain level as a per-
cent when the pulse train set in
H6-02 is input.
Set the input bias when the pulse
train is 0.
Set the pulse train input primary
delay filter time constant in sec-
onds.
