IMO Precision Controls Jaguar VXS - Control Circuits

DC Bus Reactor
NOTE If a reactor is not fitted to the inverter, it
is essential that terminals (+) and P1 remain
linked.
IMO Precision Controls Ltd recommend the
use of a DC reactor to improve the overall
power factor and to reduce the harmonics
reflected into the supply network.
Braking Terminals
Jaguar VXS inverters (except VXS20-1) are
equipped with an internal resistor to apply
dynamic braking as standard. If additional
braking torque is required, an external braking
resistor can be connected to terminals (+) and
DB.
A thermal overload sensor for the resistor is
essential to protect the inverter. The ther-
mal protection should be arranged to trip
the main power supply switch and/or termi-
nal THR, page 15. For further information,
refer to Chapter 9.
5.3 Control Circuits
FWD/REV Input Terminals
At the time of shipment, terminals FWD-P24
are connected by a solid link and Function 02
is set to the default value 0. This puts the
inverter in keypad operating mode, in which
the inverter is operated by the RUN and STOP
keys.
NOTE Whilst terminal FWD or REV is
connected to terminal P24, Function 02
cannot be changed.
To reverse the direction of motor rotation in key-
pad mode, link terminal P24 to REV instead of
FWD as shown in the diagram above.

WARNING
The RUN and STOP inputs, whether at the
keypad or terminals FWD or REV, should
not be relied upon to ensure the safety of
personnel. If a safety hazard could arise
from the unexpected starting of the motor,
an interlock mechanism should be provided
to prevent the motor from starting except
when it is safe for it to do so.

WARNING
The STOP pushbutton on the keypad is
effective ONLY when Function 02 = 0. If
Function 02 is set to 1, an external
RUN/STOP control circuit may be required
at terminals FWD or REV for safety. The
factory-fitted link, shown below, should be
replaced by an external control contact.
