Pr-08 I Gain of PID Controller
ㆍ It is relevant to ‘I’ (Integral Constant) out of PID control parameters.
ㆍ PID I-Gain 1 second means the time required for the output power to be accumulated to 1.0[Hz]
when 100 bar error is maintained.

Pr-09 D Gain of PID Controller
ㆍ It is relevant to ‘D’ (Differential Constant) out of PID control parameters.
ㆍ PID D-Gain means that change rate of error for a specified time will be out on PID control cycle
time.
Factory Setting Input Range
Pr-10 PID Control Cycle
ㆍ It sets up PID control cycle.
ㆍ It outputs values calculated with PID in PID control cycle time unit.
Factory Setting Input Range
Pr-11 Freezing Prevention Function
ㆍ It sets up freezing prevention mode of pump.
ㆍ It is to prevents pump from being broken due to low temperature (below zero) in winter using
ambient temperature sensor information within the drive. The function is operated with a
frequency not generating pressure between 0~10 seconds and maintained as stopped status
between 11~59 seconds based on 1 minute. This function is to prevent the pump from
freeze and burst by generating frictional heat upon rotation within pump casing.
This function is not for preventing freeze and burst of pipe.
