Selection and protection of a motor
(2) 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 with the RT signal on.
For the RT signal, set "3" in any of Pr. 178 to Pr. 182 (input terminal function selection) to assign the function.
REMARKS
The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 116)
NOTE
Changing the terminal assignment using Pr. 178 to Pr. 182 (input terminal function selection) may affect other functions.
Make setting after confirming the function of each terminal.
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 General-purpose magnetic flux vector
control.
