Figure 19: Example: Parallel connection of several motors to one variable frequency drive
￫
When using vector mode (P-60 = 0), two motors with identical
output classes can be connected (e.g., calendar drive).
￫
When using vector mode with P-60 = 2, 3 or 4, it is not
permissible to run multiple motors connected in parallel!
