1) Basic Operation
APP-01 APP Mode : If you select No. 3 MMC as the applied function, the items related to the MMC function are
displayed in the option card function group(APO) and the PID control related functions are displayed in APP. In APP,
application functions group, functions such as PID control are displayed.
APO-20, 21, 33 : If the number of auxiliary motors is set at APO-33 and there are more than one auxiliary motor, the
number of the auxiliary motor first operated is input into APO-21. For example, if there are three auxiliary motors and
each of them is controlled by Relay 1,2 and Q1 control, the auxiliary motors operate in the sequence of Relay 2, Q1
and Relay 1 when 2 in input in APO-21. The auxiliary motors stop in the sequence of Relay 1, Q1 and Relay 2. In
the APO-20, the number of currently operating auxiliary motors can be monitored.
APO-23~26 Start Freq 1~4 : The starting frequency of auxiliary motors is set. As the main motor is operated by PID
control, its operating frequency is risen by the load change and the operation of an auxiliary motor is necessary. The
condition of the output terminal of the inverter(Relay or multi-function output(Qx)) being ON for the operation of an
auxiliary motor is as follows. The auxiliary motor can operate when 1) the speed of the main motor rises above the
starting frequency(APO-23~26) of the auxiliary motor, 2) the starting delay time(APO-13) of the auxiliary motor
passes and 3) the difference between the reference and the feedback of the main motor PID controller becomes
larger than the pressure difference of the auxiliary motor motion(APO-40).
APO-27~30 Stop Freq 1~4 : The stop frequency of the auxiliary motor is set. If the operating frequency of the main
motor goes down below a certain frequency while the auxiliary motor is running, the auxiliary motor should be
stopped. The condition of the auxiliary motor being stopped is as follows. The auxiliary motor can be stopped when
1) the speed of the main motor goes down below the stop frequency(APO-27~30) of the auxiliary motor, 2) the stop
delay time(APO-32) of the auxiliary motor passes and 3) the difference between the reference and the feedback of
the main motor PID controller becomes smaller than the pressure difference(APO-40) of the auxiliary motor motion.
