(14):17-3 Output Filter Time (O) 0.0 – 2.5 sec
Smooth the PWM output by increase filter time setting.
Setting a bigger filter time will get a slower system response time.
(15):17-4 Feedback Signal (F) Offset 0.00 – 10.00 rate
17-5 Signal Type 0000 : 0 ~10V 0001 : 4 ~ 20mA
17-6 Feedback Signal Scan Time 1 – 100 (base on 4ms)
17-4 Feedback Signal Offset(F): Gradual adjust to specific value
Example: When the feedback signal were not the same as keypad display, adjust this
parameter to reduce the bias.
17-5 Feedback Signal Type(F): select a signal type depends on the pressure sensor
specification for the voltage type 0 ~ 10V and current type 4 ~ 20mA.
17-6 Feedback Signal Scan Time(F) setting range 1 ~100 : To set a Scan Time for
feedback signal, increasing the setting will get slower response.
Example: Set 17-6 to 5, it will automatically multiply 4ms derive a 20ms scan time. Every
20ms, inverter detect feedback signal once.
