Error Correction:
DFT Input Circuit
Revision A incorrectly stated that the drive fault input (DFT pin on the DRIVE connectors)
shared the same circuit design as the limit inputs and trigger inputs. DFT is not controlled by
the AUX-P pullup terminal and is not affected by the R45 resistor. The DFT input circuit is:

Clarification:
BD-E Drive Connections
With a BD-E drive connected as illustrated in revision A, the motor has a tendency to lunge for
several revolutions at full torque when power is removed simultaneously from the OEM6250 and
the BD-E drive (as would be the case in a power outage). The correction is to connect the
OEM6250’s SHTNC terminal to the BD-E’s GND terminal (pin 4).

NOTE: These connections will work only if
BD-E jumper LK2 is set to position B
(not the factory default position).
