9.1.4 SVM1-40i and SVM1-80i
Example for sharing a magnetic contactor
This subsection shows a connection example of a 2-axis system using
the SVM1-80i for the first axis (the unit nearer the CNC) and the
SVM1-40i for the second axis.
In this example, a separated regenerative discharge unit is connected
but no external pulse generator is connected for the first axis, while no
separated regenerative discharge unit is connected but an external
pulse generator is connected for the second axis.

CAUTION
1 A circuit breakers, magnetic contactor, and AC line filter are
always required.
2 Use the stabilized 24VDC power supply for the
β
i
SVM.
24VDC power supply for the
β
i
SVM and 24VDC power
supply for the motor brake cannot be shared.
3 If an alarm that turns off the magnetic contactor is issued in
an amplifier, an alarm indicating DC link voltage shortage is
issued in the other amplifiers.
