EB-60X Installation & Service Manual |
Wiring
The total number of axes allowed, per PSR4/5, depends on the PSR4/5
model and the combination of BDS4s and/or BDS5s:
•
PSR4/5-X12: a max of 4 BDS4’s or 3 BDS5s.
•
PSR4/5-X20: a max of 4 BDS4’s or 3 BDS5s.
•
PSR4/5-X50: a max of 6 BDS4’s or 6 BDS5s.
•
PSR4/5-X75: a max of 6 BDS4’s or 6 BDS5s.
(If the BDS’s are mixed, then the total number of axes that can be used
would be the max given for the BDS5s.)
XX in the cable number stands for cable length in meters. Cable length
is available from 3 to 75 meters in increments of 3 meters.
A thermal overload relay is supplied in the regen resistor kit for the 50
and 75 amp PSR4/5s. The thermal overload relay, included in the kit,
was sized for your resistance and power rating. The output contacts of
the relay must be wired to drop power to the main power contactor in a
fault condition, as shown on sheet 1.
Do not wire control power (PSR4/5 connector C1) through the main
power contactor. This is so that control power will not be removed if
PSR4/5 fault contacts open (this would turn
OFF
any fault LEDS).
All shielded cables must have shield continuity for the full length of the
cable.
Resolver cable must be individually shielded pairs.
Recommended torques for connection to terminal blocks and ground.
•
BDS4/5-3 to 20 amp and PSR4/5-12 and 20 amp
−
Max torque per UL is 12 in/lb, external regen, main power and
BUS connection.
−
Max torque 12 in/lb ground screw.
•
BDS4/5-30 to 55 amp
−
Max torque 20 in/lb motor, BUS connection and ground stud
•
PSR4/5-50 to 75 amp
−
Max torque 20 in/lb main power, BUS connection and ground
stud
−
Max torque 12 in/lb external regen connection
For grounding to machine or earth ground. A screw lug should be
attached to ground screw or stud. Recommended torque of 12 in/lb for
ground screws and 20 in/lb for ground studs. May also refer to national
electrical code (NEC) or UL standard 486B for recommended torques.
Thermal overload protection
DOES NOT
provide internal to amplifier
and must be provided external. Refer to national electrical code for
proper sizing of overload protection.
