5.15 Motor and macro switchover
5.15.1 Function description
The VFD provides three sets of motor parameters, and you can switch between motors through the
terminal switching function. First, you need to set the ones place of P08.31 to 0, and then use input
terminal function 35 (switching motor 1 to motor 2) and input terminal function 88 (switching to motor
3) to perform motor switchover.
In addition, application macros can be switched. Set P90.03 to set the terminal-based method of
switching application macros, and set P90.00 and P90.01 to select application macros. After the
corresponding motor is switched, the application macro is switched accordingly.
Note:
1. 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.
2. 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.
3. 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.
5.15.2 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.
