200 Watt Passive Shunt Module
(Catalog Number 9101-1183)
Drives can require external power dissipation when large inertial
loads are present. To ensure that faults due to excessive bus voltage
do not occur, loads requiring power dissipation that exceed the
internal shunt capability require the use of external shunt resistor.
The passive shunt (Catalog No. 9101-1183, formerly 9101-1079) can be
used with the following products:
As a motor decelerates, power is returned from the motor to the drive,
causing the bus voltage to increase. Ultra servo amplifier products
have circuitry that senses the voltage on the DC bus and dissipates
power when needed. When the bus voltage reaches the shunt turn-on
voltage, the internal shunt circuitry allows the excessive regenerated
power to be dissipated through an external resistor. After the bus
voltage is reduced to the turn-off voltage level, the shunt transistor
turns-off and no additional power is dissipated by the shunt resistor.
