Parameter
NOTES
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 = 9999 (analog variable) or
Pr. 79 = 6 (switchover mode).
When the Pr. 128 setting is "20, 21, 120 or 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 com-
mand value calculated by PID operation using 0Hz as standard is used without the fre-
quency during the operation.
