Output volume
Formula for output volume:
Output Volume = (Output Upper Limit – Output Lower Limit) × Output % + Output Lower
Limit
Example:
Control with current 4 ~ 20mA (0 ~ 32,000)
Output upper limit: 32,000
Output lower limit: 0

PID_RUN/STOP
1. To apply the auto-tuning function, enable the auto-tuning function before changing the
PID function to RUN. When auto-tuning is completed, CR#136, 156, 176, 196 will
be cleared to 0, and the value for K
P
/ K

will be stored into the corresponding
CRs.
2. PID_RUN/STOP, K0: STOP, K1: RUN. Default = K0.

Auto-tuning
1. To apply the auto-tuning function, set the auto-tuning CR to K1 to enable the auto-tuning
function before changing PID function to RUN. When auto-tuning is complete, CR#136,
156, 176, 196 will be cleared to 0, and the value of K
P
/ K

/ K
D
will be stored
into the corresponding CRs.
2. Auto-tuning, K0: Disabled, K1: Auto-tuning. Default = K0.
Notes:
1. Set
K
P
, K
I
, and K
D
to “0" to disable the PID function. If you want to use proportional control
only, set K
I
and K
D
to “0”.
