Note:
Switching from motor 1 to motor 2 takes priority over switching from motor 1 to motor 3. That is,
the signal for switching from motor 1 to motor 3 is detected only after no signal for switching from
motor 1 to motor 2 is detected.
The motor parameters for motor 2 are separate from those for motor 3. Group P12 and group
P29 contain motor parameters for motor 2 and motor parameters for motor 3. However, motor 2
and motor 3 use similar parameters for control modes, such as VF and vector control parameters.
During motor switching, the terminals to which application macros have assigned values cannot
be used for switching. Otherwise, if an application macro changes the value assigned to a
terminal, the value is overwritten, resulting in switching failure.
5.11.2 Description about switching from motor 2 to motor 3
The terminal input function does not contain the ability to switch from motor 2 to motor 3. To switch
from motor 2 to motor 3, remove the signal for switching from motor 1 to motor 2, and then input the
signal for switching from motor 1 to motor 3. If the signal for switching from motor 1 to motor 2 and
switching from motor 1 to motor 3 are given simultaneously, the signal for switching from motor 1 to
motor 2 is affected since the switching from motor 1 to motor 2 has higher priority (as mentioned
earlier), and motor 2 is used automatically.
Example:
If S1 is set to have terminal function 35 (for switching from motor 1 to motor 2) and S2 is set to have
terminal function 88 (for switching from motor 1 to motor 3), there are four types of combination:
S1 status
