Bulletin VPC Motors and the Extended Speed Feature
The extended speed feature is implemented in the Logix Designer application
to prevent accidental motor operation at unsafe speeds. See
for a description of this feature.
Powerohm Bulletin PKB and PWB active-shunt modules are required for DC-
bus system protection when Bulletin VPC motors are expected to operate in
the extended speed region at speeds exceeding the bus-overvoltage speed limit.
Considerations for Powerohm Shunt Installation
Refer to the Powerohm documentation included with your Bulletin PKB or
PWB shunt module to install, wire, and configure the module.
• To avoid nuisance thermal overload trips, configure Bulletin PKB and
PWB active-shunt modules to the highest shunt turn-on voltage setting.
The recommended setting for Line Voltage Level Jumper is JP5.
• Configure Bulletin PKB and PWB active-shunt modules in Internal
(automatic) mode. Unless an external enable signal is provided,
configure the Brake Enable Jumper in Internal (automatic) mode ( JP6 is
in the downward position).
WARNING:
Bulletin VPC motor operation at speeds exceeding the bus-
overvoltage speed limit can result in personal injury and/or damage to the
drive. To avoid equipment damage and personal injury, an active shunt must
be configured in the Logix Designer application to protect the DC-bus system
from an overvoltage condition.
IMPORTANT
Refer to Motion Analyzer software to verify drive/shunt system sizing.
