CAUTION
If the multi-speed (RH, RM, RL signal) or Jog operation (JOG signal) is entered with the X14 signal on, PID control is stopped
and multi-speed or jog operation is started.
If the setting is as follows, PID control becomes invalid.
Pr. 22
Stall prevention operation level
= "9999" (analog variable)
Pr. 79
Operation mode selection
= "6" (switchover mode))
When the
Pr. 128
setting is "20, 21, 120, 121", note that the input across inverter terminals 1-5 is added to the set value across
terminals 2-5.
Changing the terminal function using any of
Pr. 178 to Pr. 189, Pr. 190 to Pr. 196
may affect the other functions. Please make
setting after confirming the function of each terminal.
When PID control is selected, the minimum frequency is the frequency set in
Pr. 902
and the maximum frequency is the
frequency set in
Pr. 903
. (
Pr. 1 Maximum frequency
and
Pr. 2 Minimum frequency
settings are also valid.)
The remote operation function is invalid during PID operation.
When the control is switched to PID control during
normal operation, the frequency command value
calculated by PID operation using 0Hz as standard is
used without the frequency during the operation.
