Make sure that water/oil pressure bypass interlocking is tuned as per the programmed
acceleration time of VFD.
Without Built-in PID of VFD
Select Frequency Reference - If it is 0~10V signal, than
C03-D = 16 (On fixed, AFS1 speed setting1)
Connect 0~10V signal wire at VFD’s terminal board as below
0~10V signal (at COM & AI1 terminal)
Select Frequency Reference - If it is 4~20mA signal, than
C03-D = 0 (Off fixed, AFS1 speed setting1)
C03-E = 16 (On fixed, AFS2 speed setting2)
C12-4 = 2: Current input, 4-20mA
Connect signal wire on the VFD control terminal board
4~20mA signal (at COM & AI2 terminal)

ON the DIP switch DS1-3 that is available on VFD control board.
Minimum Operating Frequency
Consult to customer for minimum allowable operating frequency (speed) of the compressor which is
declared by manufacturer. If data is not available than program minimum frequency as per below.
B07-1=35Hz (approx 70% of motor base frequency).
