SD315O 3 Technical Data
Drive for stepper motors 21
3.3.2 Supply voltage VDC at CN1
The power stage supply VDC is also the controller supply voltage.
Electrical data
Fuse to be connected upstream The input current may increase greatly for a short periods in the case of
dynamic processes such as fast acceleration or brief load torque peaks.
Circuit breakers with thermal tripping are recommended.
For example type multi9 C60N by Schneider Electric, Cat.No.60110,
rated current 10 A, trip characteristic C.
Alternatively, circuit breakers with electronic tripping can be used.
For example type ESS20 by E-T-A.
Select the nominal current of the circuit breaker depending on the wiring
and the input current.
