Parameter Selection and protection of a motor
FR-E700 SC EC/ENE 6 - 89
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.

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.
