Don't fit a standard fuse between the drive and motor. If the fuse blows
the sudden disconnection of the load will very probably damage the
drive. If you use anything, try a resettable semiconductor fuse. They
switch relatively slowly so they won't damage the drive. They also have
a high thermal inertia so they will allow short peaks of high current
without blowing.

If you aren't running the motors close to their maximum I would suggest
a 5A or 6A fuse.
