BPS
If an optional 24VDC power supply or battery backup is used instead of the BPS, the
connections to X10 must be made as shown in Figure 2-5. This allows position
information and other memory related information to be stored when AC power is
removed from the BPS.

Supply
An external DB (Dynamic Brake) resistor must be installed to dissipate excess power
from the DC bus during motor deceleration operations. For selection of the DB resistor,
refer to the specifications located in Section 3 of this manual. DB hardware is connected
at the R1 and R2 terminals.
