The maximum voltage allowed between Bus/Ctrl Gnd and chassis is 100
VDC.

Bus Capacitance
There is a minimum requirement on the output capacitance of the bus power
supply for the DC input S200. This capacitor is needed to absorb energy during
motor deceleration and motor disable and to help provide energy during motor
acceleration. For multiple S200 drives operated from one supply the
recommendation is to increase the capacitance according to the number of
drives. For example, for four 6 A / 18 A
RMS
DC S200 drives powered from one
75 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.
