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:
Drive
ULTRA 200™ Drives
ULTRA Plus™ Drives
Ultra3000™ Drives
Ultra5000™ Drives
Using the passive shunt with modules not listed can
ATTENTION
cause equipment damage or personal injury.
!
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.

- Page 2 200 Watt Passive Shunt Module Installing the Shunt Orientation and Clearance The following enclosure restrictions must be considered because the shunt module dissipates excess regenerative power in the form of heat. Refer to Figure 1 for shunt module spacing requirements. Figure 1 Shunt Module Spacing Requirements Within an Enclosure Do not mount temperature...
- Page 3 200 Watt Passive Shunt Module If the work environment dictates, mount the shunt module in an enclosure providing protection against dust and splashing water (IP54), or dust free and protected against water jets (IP65). Avoid contaminating electronic components. ATTENTION Provide a quality air source to cabinets; free of debris, oil, corrosives, or electrically conductive contaminates.
