1. Functions
a) Controlling multiple motor type (up to four motors with the same rated voltage, number of poles, and
capacity) while switching from one to another.
(Motor type : Toshiba standard motor, Toshiba VF motor, Toshiba V3 motor)
(Especially when controlling them in vector control mode (V/f control mode selection (pt): 2 to 9) for
which motor constants need to be specified)
b) Switching V/f control modes (V/f1 to V/f4) by sending a signal to input terminals, and performing
operation in V/f2 to V/f4 modes under the same conditions specified for V/f1, using the V/f control mode
selection parameter (pt)
For the operations described above, use this function along with the V/f switching signal 1 or 2.
Note 1:The functions described in 6.4.1, “Switching among V/f characteristics #1, #2, #3 and #4 from input
terminal,” of the inverter’s instruction manual are also activated when this function is used, so that
the parameter selected needs to be set as required.
Note 2:Motor constants 1, 2, 3 and 5 (f402, f403, f404 and f410), which need to be specified
according to the motor used, cannot be changed.
Note 3:V/f control mode selection parameter settings (pt) cannot be switched on a motor-by-motor basis
(V/f1 to V/f4).

3. Example of operation
To operate 3.7 kW four-pole motors in sensorless vector control mode while switching them by sending a
signal to the S1 and S2 terminals
(1) Set the parameters as follows; cmod=0, pt=3, f182=1, f115=28, f116=30, f411=4,
f412=3.7
(The parameters described in 6.4.1, “Switching among V/f characteristics #1, #2, #3 and #4 from input
terminal,” of the inverter’s instruction manual also need to be set for each motor.)
(2) The settings of f402, f403, f404 and f410 are changed by turning on or off the S1 and S2
terminals, as described in Table 1 below, and motor data is according to the type of motor used.
S1 S2 Settings of f402, f403, f404 and f410
OFF OFF TOSHIBA standard motor #1
ON OFF TOSHIBA VF motors
OFF ON TOSHIBA V3 motors

ON ON TOSHIBA standard motor #2
* If any number of poles or capacity other than those of the Toshiba motors is specified, an “etn” trip
will occur.
