ECM Overview and Setup

Overview

This section addresses integrating the new Trane
electronically commutated motor (ECM) and VelociTach™
motor control board. This exciting new series delivers
outstanding comfort, safety, and performance with greatly
reduced energy consumption compared to traditional units
with induction AC motors.
The new series of units will provide a long service life with
proper installation and operation. The new system provides a
high degree of flexibility and configurability, but the simplicity of
customized factory configuration appropriate to most
installations.
Very little intervention is needed by service and installation
personnel in most applications; however, installers must read
through the entire document before beginning installation of
the new equipment.
This literature focuses on unit motors and controls, including
three new circuit modules developed specifically for this
series.

The primary components that enable the technology on your
product:
• Trane electronically commutated motor (ECM)
• VelociTach™ motor control board
• Standard adapter board (ZN control only)
• CSTI adapter board (CSTI control only)
The motors and modules are combined as systems, and
cannot work without each other.

• The ECM has integrated electronics, overload protection
and short circuit protection. The motor contains no user-
serviceable components inside.
NOTICE
Equipment Damage!
Failure to follow this instruction could result in
equipment damage. The motor harness attached to the
single plug to which the motor mates contains the very
important motor voltage jumper and should not be
modified or substituted.
• The motor mates to the unit electrically via a single plug
that contains both the operating voltage and the control
signals that are needed for correct operation.
