5: Multi-step speed set
6: MODBUS communication set
The setting target of procedure PID is a relative
one, 100% of the setting equals to 100% of the
response of the controlled system.
The system is calculated according to the relative
value (0
–100.0%).
Note:
Multi-step speed reference, it is realized by setting
P10 group parameters.

When E09.00 =0, set the parameter whose basic
value is the feedback value of the system.
The setting range: -100.0%

PID feedback
source
Select the PID channel by the parameter.
0: Analog channel AI1 feedback (implemented
through the analog potentiometer on the keypad
for the 0150G/018P and lower models; not
available for the 018G/022P and higher models.)
1: Analog channel AI2 feedback
2: Analog channel AI3 feedback
3: High speed HDI feedback
4: MODBUS communication feedback
5: MAX(AI2,AI3)
Note: The reference channel and the feedback
channel cannot coincide, otherwise, PID cannot
control effectively.

PID output
feature
0: PID output is positive: When the feedback
signal exceeds the PID reference value, the output
PID. For example, the strain PID control during
wrap-up
1: PID output is negative: When the feedback
signal is stronger than the PID reference value,
balance the PID. For example, the strain PID
control during wrap-down

Proportional
gain (Kp)
The function is applied to the proportional gain P
of PID input.
P determines the strength of the whole PID
adjuster. The parameter of 100 means that when
