An adequately sized bus capacitor helps provide the high peak bus current needed for rapid motor acceleration with minimum bus voltage sag. If the bus voltage sags excessively during acceleration, inverter voltage saturation occurs with loss of motor torque. 4. Bus capacitance lowers peak current requirements in the silicon of the power supply. Sizing the power supply for average power, rather than peak power, lowers power supply cost and size. 5. In most cases, a bus capacitor does not need to be mounted close to the drive. The inductance of the bus and ground wiring is not critical because the internal drive bus capacitance generally handles all the PWM current of the drive. A local capacitor is not needed in the following cases: 3/9 ARMS DC S200 6/18 ARMS DC S200 with HSTemp less than 65° C 6/18 ARMS DC S200 mounted adjacent to other S200 drives with main bus supplies tied locally together. The internal bus capacitors of the adjacent drives should provide the needed capacitance. The exception is a single, isolated 6/18 ARMS DC S200 drive running hot (HSTemp > 65° C). In this case, connect across the bus within 1 ft of the drive, using twisted wire, a 470 µf (min), 100 V, low ESR, and an aluminum bus capacitor. 6. Bus capacitor for multiple drives A conservative rule is to scale up the recommended output capacitance for one drive by the number of drives. If this value is too large, the capacitor can be calculated from energy flows. See the A.4 Bus Energy & Power Numerical Examples. NOTE Bus capacitance can be tweaked experimentally. Increase bus capacitance if there are overvoltage trips. In general, there is sufficient bus capacitance if the bus voltage variation is ± 5 V (from 75 VDC) during the machine cycle. Check the bus voltage with an oscilloscope. Scope ground on J1-2 (Bus/Ctrl Gnd) and probe on J1- 3 (+bus), Hor: 5 ms / div. NOTE Some bus voltage variation is normal and required for the output bus capacitor to supply or absorb energy. 7. Bus over-voltage fault (non-latching) If regeneration is too high while bus capacitance is too low, the bus voltage rises to the bus over-voltage fault threshold and disables the drive transistors. It typically takes 1 to 2 ms for the motor current and torque to go to zero. 

After it has reached zero, there is no further rise in the bus voltage. When the bus capacitors discharge to below the overvoltage threshold by a hysteresis value, the over-voltage fault is cleared and normal operation resumes. While this protects the drive by limiting the bus voltage rise, it may not be desirable because it interrupts normal motor torque. 8. Unregulated power supply External bus capacitance requirements are usually met by the output capacitor in an unregulated power supply, as long as there is no diode between the drives and bus capacitor. The same capacitor that filters the 120 Hz or 360 Hz line ripple also provides energy leveling and regeneration absorption capability.
