9.1.3 SVM1-4i and SVM1-20i
Example for sharing a magnetic contactor
This subsection shows a connection example of a 2-axis system using
two SVM units which are the SVM1-4i or SVM1-20i.
In this example, a separated regenerative discharge unit is connected
but no external pulse generator is connected to the SVM unit for the
first axis (the unit nearer the CNC), while no separated regenerative
discharge unit is connected but an external pulse generator is
connected to the SVM1unit 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
βi
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.
