(1) For frame B and C drives only, a jumper is required between terminals SA and SB for 115V AC control input power. See Control Circuit Input Power on page 65 for more information.
(2) An Isolation Transformer and/or 3…5% impedance Line Reactor is required. If the Isolation Transformer provides the required 3…5% impedance, a Line Reactor is not required. See AC Input Line Reactors and AC Input Contactors on page 238
and Isolation Transformers on page 241 for
recommendations.
(3) AC input fuses for the armature converter are customer supplied for frame A and B drives and are internally mounted on frame C and D drives. See Drive Power Circuit Protection on page 219
for fuse recommendations.
(4) Par 140 [Digital In8 Sel] set to 31 “Contactor”
(5) If using the +24V internal power supply, terminal 18 (24V common) must be jumpered to terminal 35 (digital input common).
(6) Customer supplied armature output fuses are required on four quadrant and are recommended on two quadrant Frame A and B drives. See Drive Power Circuit Protection on page 219
for fuse recommendations.
(7) Optional armature voltage feedback sensing not required with AC contactor.
(8) Par 1391 [ContactorControl] = 1 “AC Cntctr” and Par 1392 [Relay Out 1 Sel] = 25 “Contactor”. Important: Terminal 35 and 36 are on the Control Power / Relay Outputs Terminal block, NOT the I/O terminal blocks. See Figure 35
on page 63…Figure 37 on page 64.
(9) Frame C & D drives only require an external power supply for the heatsink cooling fan. See Frame C Heatsink Cooling Fans Power Supply Terminals on page 68
and Frame D Heatsink Cooling Fan Power Supply Terminals on page 69 for more information.
