Functional sequence
Figure 83: Functional sequence of two-motor changeover
Note:
Motor changeover must be completed within two seconds, otherwise
"Motor 1/2" fault message appears and drive is switched off.
The auxiliary contactors must also change the temperature sensors of
the motors, otherwise the active motor is not monitored.

Figure 82: Parameters for two-motor changeover
Note: The values 1 or 2 must always be assigned to the G-CHANGE
parameters in the four switchable parameter records. 0 is not allowed!
No spindle position can be performed via the spindle position encoder
during two-motor changeover as the second encoder input is used for
motor feedback from the second motor.
