Chapter 12 Description of Parameter Settings|CFP2000 Series
12.1-12-8
I/F mode, low pass-filter time
Factory Setting: 0
Settings 0: Turn off all output
1: Motors powered by mains electricity continues to operate
Initial Angle Detection Time
Factory Setting: 0
Settings 0.00 to 600.00 Hz
When the output frequency is smaller than the setting value of Pr12-08 and remains at the time
setting of Pr12-04, motors will be shut down one by one.
Fixed quantity control with PID
In this mode, CFP2000 can control up to 8 motors to increase controlling flow quantity and pressure
range.
CFP2000 connects directly to a main motor while the rest of motors are using mains electricity and
controlled by a relay. When controlling flow quantity, motors will be in parallel connection. When
controlling pressure range, motors will be in series connection
If need to increase flow quantity or pressure range, CFP2000 will increase the main motor’s pressure
from 0Hz to the largest operating frequency. If necessary, CFP2000 will switch in sequence the
motors to use mains electricity. See sequential diagram of 12-8 and 12-9.
