*2. Recommended relay: MY relay by
OMRON (24-V type) For example, MY2
relay by OMRON can be used with all
G5-series motors with brakes because
its rated induction load is 2 A (24 VDC)
.
*3. There is no polarity on the brakes.
*4.
The Regeneration Resistor built-in type (KT20H)
shorts B2 and B3. When the amount of
regeneration is large, remove the connection
