Chapter 2 Drive System Layout
Hall Effect Current Sensors (HECs)
The Hall Effect Current Sensors are current transformers capable of
measuring current throughout the output frequency range of the drive. They
monitor the current waveform in each of the phases going to the motor and
provide feedback to the control system.
Top-mounted Cooling Fans
The top-mounted cooling fans deliver reliable cooling of the Power Modules.
They draw cool air in through the vents in the Power Module cabinet doors,
through the Power Modules, and exhaust out the heated air through the top of
the cabinet.
LV Control Cabinet
The LV Control cabinet consists of the Control Unit, the human machine
interface (HMI), PLC, AC/DC power supplies, contactors, and relays.
The HMI is on the front door of the LV Control cabinet, where an operator can
set up, monitor, and control the drive.

IMPORTANT
When wiring a power supply to the Phoenix connectors, verify the
configuration on the markings and labels. Some power supplies may
use two 6-pin connectors with similar configuration but have a
different voltage input.
