Parameter
Use two motors (Pr. 450)
● Set Pr. 450 "Second applied motor" to use two different motors with one inverter.
● When "9999" (initial value) is set, no function is selected.
● When a value other than "9999" is set in Pr. 450, the second motor is valid when the RT
signal turns on.
● For the RT signal, set "3" in any of Pr. 178 to Pr. 184 "Input terminal function selection" to
assign the function.
NOTES
The RT signal acts as the second function selection signal and makes the other second
functions valid. (Refer to section 6.10.3.)
Changing the terminal assignment using Pr. 178 to Pr. 184 "Input terminal function
selection" may affect other functions. Make setting after confirming the function of each
terminal.
b
CAUTION:
● Set this parameter correctly according to the motor used. Incorrect setting may
cause the motor to overheat and burn.
● Set the electronic thermal relay function to the thermal characteristic for the
constant-torque motor when using a geared motor (GM-G, GM-D, GM-SY, GM-HY2
series) to perform advanced magnetic flux vector control or general-purpose
magnetic-flux vector control.
