S200 Position Node Installation Guide
VDC supply the recommended minimum bus output capacitance of the supply is 4 x 4,000 µf =
16,000 µf. Bus capacitor voltage rating should be 100 V. Bus capacitor type is aluminum
electrolytic.

USING
Do not put E-Stop switches or contactors between the drive bus pin (J1-3) and the power
supply bus capacitor. There is a risk of damage to the drive if the bus is disconnected from the
power supply capacitor when the drive is enabled. The motor does not need to be rotating to
regenerate energy. The motor windings store magnetic energy that regenerates back to the
supply when the drive is disabled.
E-stop switches can safely be located in series with the primary winding of a step down
transformer. If individual axis E-Stop switches are required, connect a local (unswitched)
capacitor (1,000 µf, 100 V) across the drive bus terminals (J1-3 to J1-2).
If the buses of individual drives are to be fused, select the fuse type and rating for high margin.
