9.4 BUS SWITCHING AND FUSING
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.
