1336 PLUS II and IMPACT
Drives
To increase the distance between the 1336 PLUS II and IMPACT drives and the
motor, some device (RWR or terminator) needs to be added to the system.
Shaded distances are restricted by cable capacitance charging current.

(1) Some Frame 9 and all Frame 10 drives require two reactors to match drive amp rating. The resistor ratings are per phase values for each reactor.
(2) Resistor specification is based on two parallel cables per phase.
(3) Resistor specification is based on three parallel cables per phase.
(4) Resistor specification is based on four parallel cables per phase.
