Operation selection function
REMARKS
•If the multi-speed (RH, RM, RL signal) or jog operation (JOG signal) is entered, PID control is
stopped and multi-speed or jog operation is started.
•Changing the terminal functions using Pr. 60 to Pr. 65 may affect the other functions. Confirm
the functions of the corresponding terminals before making settings.
•When PID control is selected, the minimum frequency is the frequency set in the calibration
parameter C2 and the maximum frequency is the frequency set in Pr. 38.
(The Pr. 1 "maximum frequency" and Pr. 2 "minimum frequency" settings are also valid.)
•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.
