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:

Ultra5000™ Drives 2098-IPD-030, -030-DN, -075, and -075-DN

ATTENTION

Using the passive shunt with modules not listed can 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.

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.

Do not mount temperature sensitive components above shunt module

87 mm (3.4 in.) min. of clearance on

each side of the shunt module.

Do not mount shunt module

on its side

ATTENTION

The shunt module can release a large amount of heat over time.

Any materials above the shunt module or its enclosure may need the protection of a metal plate to keep from deteriorating.

Failure to observe this precaution could result in damage to surrounding materials, possibly leading to fire.

The shunt module can release a large amount of heat inside an enclosure.

Ensure there is enough ventilation so as the maximum ambient temperature of 50° C (122° F) is not exceeded.

Failure to observe this precaution could result in damage to the shunt module.

200 Watt Passive Shunt Module 3

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).

ATTENTION

Many NEMA (National Electrical Manufacturers Association) Type 4 cabinets provide this level of protection.

ATTENTION

Avoid contaminating electronic components.

Provide a quality air source to cabinets; free of debris, oil, corrosives, or electrically conductive contaminates. All cabinets should have scheduled inspections and be cleaned as needed.

Failure to observe these safety procedures could result in breakdown and damage to equipment.

If you mount the shunt module inside a cabinet, you must make sure that the ambient temperature inside the cabinet does not exceed 50° C (122° F).

Shielded metal conduit, and ferrite filters are also recommended for reducing the effects of EMI.

Only one passive shunt module can be used per drive or damage to the drive will result.

87 mm (3.4 in.) minimum clearance on all sides of the shunt module

Always separate low voltage signal wiring from high voltage power wiring to reduce affects of EMI.

Publication 2090-IN003A-EN-P — November 2002

When shielding is used, the shield must be grounded to the shunt and drive as is the motor power cable.
