Multi-Function Digital Inputs (H1-01 to H1-05)
Set Value
19 PI control disable (ON: PI control disabled)
30 PI control integral reset (reset when reset command is input or when stopped during PI control)
31 PI control integral hold (ON: Integral hold)
34 PI soft starter
35 PI input characteristics switch
Multi-Function Analog Input (H3-09)
Set Value
B PI feedback
C PI target value
16 PI feedback 2
PI Control Methods
There are four PI control methods. Select the method by setting parameter b5-01.
Set Value
1 PI output becomes the Inverter output frequency.
3 PI output is added to the frequency reference as compensation value of the Inverter output frequency.
PI Input Methods
PI Target Value Input Methods
Select the PI control target value input method according to the setting in b1-01 (Reference Selection).
Normally, the frequency reference selected in b1-01 is the PI target value, but you can also set the PI target
value as shown in the following table.
PI Target Input Method
MEMOBUS register 0006H
Parameter setting
If the PI function is used, the frequency reference value becomes the target value, which is set and shown
in Hz on the operator. Nevertheless, internally the PI target value is used in percent. I.e. the following
formula is used:
INFO
PI target value [%] =
Control Method
Set MEMOBUS bit 1 in register address 000FH to 1 (enable/disable PI target value from commu-
nications) to be able to use register number 0006H as the PI target value.
If b5-18 is set to 1 the value in b5-19 becomes the PI target value.
