• If PID Control Selection (n128) is set to 0 (disabled), or a PID cancel
input using a multi-function input is ON (Bi-directional Range Func-
tion Enabled):
If the input frequency reference is from 0% to 50%, the input rotation
direction command will be reversed. If the reference is from 50% to
100%, operation will be performed without reversing the input rota-
tion direction command.
The frequency reference at this time is shown in the following dia-
gram. (The diagram shows operation when a Forward Run Command
is input.) (If Reverse Run Prohibit (n006) is set to 1, however, reverse
operation will not be performed and the frequency reference will be
limited to 0 Hz.)
PID Analog Output of the PID Feedback Value
If the Monitor Item Selection (n066) is set to 7, the PID feedback value
will be output as an analog value.
