*1. A recommended product is listed in 4-3,
Wiring Confirming to EMC Directives.
*2. Do not use shielded cables for power cables.
*3. Recommended relay: MY relay by OMRON
(24 VDC 2A)
Select one that matches the ratings of the
brake etc. to be used.
*4. Model with a built-in Regeneration Resistor
(KN30F-ECT-L) has B2 and B3 shorted.
When the amount of regeneration is large,
remove the connection between B2 and B3
and connect the Regeneration Resistor
between B1 and B2.
