AC Powered Motor Drive Connectors
The AC Motor Power connectors P3 (Main) and J4 (Load) provide
switched hazardous AC power to the Main and Load/Unload Areas of the
machine. The motor power connectors have different sex terminals to
help prevent accidental cross connection.

P3 supplies power for the Main area, while J4 supplies power for the
Load/Unload area (when the dual area control option is installed). These
connectors also provide connections for the DC bus and regeneration
control circuits that are provided on most AC powered motor drives. For
specific details on wiring AC motor drives, see the diagram under the
“Wiring Configuration” section below.
The eF-785 automatically discharges any DC power stored within the
drives when the hazardous power is interrupted to those drives. 25 ohm
resistors within the eF-785 dissipate the power that is typically generated
during load deceleration. Thus, the issues presented by the
implementation of regenerative power resistors, such as thermal and
shock hazard protection, overload protection, and custom guarding, are
eliminated. Additionally, these resistors are fan-cooled in a dedicated
plenum protected by automatically resetting fuses. Over-current
protection for these circuits is provided by the main front panel circuit
breaker, CB1.
Most AC powered motor drives provide these connections and are
compatible with the internal 25-Ohm regeneration resistors. Contact
Teknic for specifics on connecting 3
rd
party servo drives to these circuits.
Over-current protection for these circuits is provided by the main front
panel circuit breaker, CB1.
By using a 6-position, 600V terminal block, AC servo drive power can
be distributed to multiple servo drives with ease. Whether there are
multiple servo drives or only one, it is important to keep the Hazardous
DC voltages and regen in a separate shielded cable due to noise generated
