Control method Parameters
5 - 44
Driving two motors under Advanced magnetic flux vector control
●
Turning ON the Second function selection (RT) signal enables the second motor operation.
●
Set a second motor in Pr. 450 "Second applied motor". (In the initial setting, "9999 (no second
motor)" is selected. Refer to page 5-291.)
Function RT signal ON (second motor) RT signal OFF (first motor)
Applied motor Pr. 450 Pr. 71
Motor capacity Pr. 453 Pr. 80
Number of motor poles Pr. 454 Pr. 81
Speed control gain
(Advanced magnetic flux vector)
Pr. 569 Pr. 89
Tab. 5-18: Switching the parameters by using the RT signal
NOTES The RT signal is a second function selection signal. The RT signal also enables other second func-
tions. (Refer to page 5-285.)
RT signal is assigned to the terminal RT in the initial status. Set "3" in any of Pr. 178 to Pr. 189 (input
terminal function selection) to assign the RT signal to another terminal.
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may
affect the other functions. Set parameters after confirming the function of each terminal.
