3.6 Connection of supply voltage
The power supply for the MSD Servo Drive is separated into the supplies for control and
power sections. The control supply must always be connected supply for the control
must always be connected
first
, so that actuation of the MSD Servo Drive can first be
checked or the device can be parameterized for the intended application.

ATTENTION!
The control supply (+24 V DC) should be dimensioned accord-
ing to the maximum current demand. Suitable measures must also be applied
to provide adequate cable protection.
NOTE:
In the case of sizes Size 1 to Size 4, in addition to the control section
the external voltage source also supplies the output for the motor holding
brake. When this output is active, the current for the control section plus the
current for the motor holding brake plus additional required current for digital
inputs and outputs flows through terminal X9. Note this when dimensioning
the voltage source for the control section and when looping-through to other
devices. For the current demand of the individual device refer appendix B in
table B.15 on page 78.
