The Ultra 800-i series drives are equipped as standard with a non-contact mag-
netic switch as a reference switch. The magnetic reference switch is fixed in the
console. The permanent magnet included in the accessory pack is attached ac-
cording to the instructions included in the accessory pack.
The distance between magnetic switch and magnet must not exceed 10 mm! If
the range of the magnets is not sufficient, a stronger magnet can be used.
