Installation Instructions
900 Watt Passive Shunt Module
Ultra Series drives and controllers can require external power
dissipation when large inertial loads are present. To ensure that drive
faults due to excessive bus voltage do not occur, loads requiring
power dissipation that exceed a drive’s internal shunt capability
require the use of external shunt resistor(s).
The passive shunt (Catalog No. 1398-SR9PF or 2090-UCSR-P900) can
be used with the following products:
As a motor decelerates, power is returned from the motor to the drive
module, causing the bus voltage on the drive to increase. Ultra servo
amplifier products have circuitry that senses the voltage on the drive’s
DC bus and dissipates power when needed. When the bus voltage
reaches the shunt turn-on voltage of the drive, 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.
