High-function General-purpose Inverter RX2 Series User’s Manual
PID output is restricted to a changeable range based on the target value.
The limitation function of PID for which 0.00 was set for the following changeable range will be disabled.
Precautions for Correct Use
In the case of using this function, set the corresponding PID changeable range
([AJ/16]/[AJ-36]/[AJ-56]). Restriction will be set with the maximum speed as 100% (PID target
value ± changeable range).
Parameter
In normal PID control, the inverter does not output a negative figure for frequency command and limits
at 0 Hz. If you select 02 (with reverse output) for each selection [AJ-01]/[AJ-21]/[AJ-41] of
PID2/PID3/PID4, frequency command can be output in a reverse direction, if the result of the corre-
sponding PID calculation was negative.
Precautions for Correct Use
When [AJ-01]/[AJ-21]/[AJ-41] is set to 02 (with reverse output), the PID changeable range limit
function [AJ-16]/[AJ-36]/[AJ-56] will be extended to the negative direction.
