(1). Set 00-05 (frequency reference selection) to 4 (serial pulse input), take the serial pulse
input terminal PI as a frequency reference. For using pulse input as reference
frequency, please refer to Figure 4.3.5.
. By setting 03-30 (pulse input) to 0 (frequency reference), select the serial pulse input
terminal PI as a function of frequency reference, and then set the number of pulse by the
parameter03-31 (pulse input scale) equaling to maximum output frequency (01-02). If
there is interference affecting performance, you can increase the value of 03-34 (filter
time of pulse input).
When setting 03-30 to 0 (PID feedback value), you need to set 10-00 = 3 or 4,
otherwise it might appear the error of SE09 "PI settingting error".
(2). PID input of pulse input (03-30 = 1 or 2)
. Use parameter10-03 (PID control mode) to perform PID control, and set the PID
feedback value and target value.
. When setting 03-30 to 1 (PID feedback value), the pulse serial input to the control
terminal PI is regarded as the PID feedback value. When setting 03-30 to 2(PID target
value), the pulse serial input to the control terminal PI is regarded as the PID target
value. Please refer to Figure 4.3.28.
When setting 03-30 to 1 (PID feedback value), you need to set 10-01 = 3, otherwise it
might appear the error of SE09 "PI settingting error".
