Chapter 8 Applied Functions
2) If there are four motors in total and the auto change mode selection(APO-35) is set at 2(Main), the operation is as
follows. If the starting auxiliary motor selection APO-21 is set at 1, motor 1 is operated by the inverter and the
remaining 2, 3 and 4 are operated by the auxiliary motors and interlock signals are input to the auxiliary motors, the
operation sequence is the same as the procedure described in 1) above. However if there is a problem with motor 1,
which is connected to the inverter, the output is immediately blocked and motor 2 gets connected to the inverter
output and the operation sequence of the auxiliary motor is 3, 4. If the interlock signal of motor 1 is withdrawn, the
operation sequence of the auxiliary motor is 3, 4, 1.
Bypass Operation (Regul Bypass)
The speed of the main motor can be controlled by the feedback without using the PID. The operation and stop of
the auxiliary motor is controlled according to the feedback amount.
APP-34 Regul Bypass : Select No. 1 Yes. If there are four main motors and auxiliary motors(APP-33) in total, the
operation is as follows. If the feedback input value is between 0~10V and operating frequency of the maximum input
value(10V) is 60Hz, the auxiliary motor 1 is started when the feedback amount is 2.5V(15Hz of main motor
operating frequency). If the feedback amount reaches 5V again, the auxiliary motor 2 is operated. At maximum 10V
input, all three auxiliary motors operated.
