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.
