Note 5. The setting range is between 0.00 and 0.1 less than the Inverter’s rated current. The value for
200-V class, 0.4-kw Inverters is shown.

Switching Control for Two Motors
Set a multi-function input 1 to 6 (the parameters H1-01 to H1-06) to 16 for motor switching. When the
motor switching input turns ON, the constants of the second motor will be selected. Switch the following
external wires to the second motor when the constants are selected. By setting the multi-function con-
tact output or the multi-function output 1 or 2 to 1C for motor selection, the status of the switching of the
motor can be checked. The output will turn ON when the second motor is selected.
•
Power wires U, V, and W
•
PG signal line (if PG is selected)
•
Peripheral circuits (e.g., a motor brake and a thermo switch for excessive heating detection)
Note 1. Two-motor switching control is not possible while the Inverter is in operation. If an attempted is
made to switch the motor while the Inverter is in operation, the message “Motor Running” will
flash.
Note 2. Switch the motor while the motor is not rotating. Do not attempt to switch the motor while it is
coasting to a stop, otherwise a main circuit overvoltage (OV) or overcurrent (OC) fault will re-
sult.
Note 3. Other than the motor constants, the same parameters are used by the first and second mo-
tors. When connecting a PG, check that the two motors have the same number of PG pulses.
The default settings of some constants vary with the motor control mode. In that case, when
the second motor is selected, the constants will be set to default values.
Motor switching selection
Motor 1 operation
Motor 2 operation

motor switching
Motor selection output
Forward (reverse) command
Approx. 200 ms
Approx. 50 ms
(Approx. 500 ms for flux vector control or
V/f control with PG feedback)
Turn ON the forward (reverse) command only
after checking the status of motor 1, motor 2,
and the motor selection monitor.

Installing Optional Cards
A maximum of three Optional Cards can be installed in the SYSDRIVE 3G3FV. The installation location
of each is determined by the type of Card. Be sure to install the Cards in their correct locations.
