EC Titanium Motor & ABB ACH580 Drive Setup
This document gives basic guidelines on how to identify motor data from the nameplate to set drive parameters in the
ACH580 when using the EC Titanium permanent magnet motors. Parameter guidelines for operation are provided basic
information for tuning the motor control performance.
For advance drive setup instruction, reference ABB ACH580 Control Firmware Manual (3AXD50000027537).
This instructions applies to the EC Titanium Motor and ACH580 products.
11.1 Overview EC Titanium Motor Design
Like the traditional Electronically Commutated motor (ECM), the EC Titanium uses permanent magnets and requires an
electronic drive to control properly. Both are synchronous and tend to be more efficient than their induction counterparts.
EC Titanium motors uses a synchronous reluctance rotor with imbedded ferrites magnets (FASR) design. The application of
ABB variable frequency drives with a EC Titanium motor enables the use of advanced motor control algorithms for higher
efficiencies across the speed load range.
The Motor Inductive values and Back EMF Voltage are important values for setting a ABB drive with the EC Titanium to
ensure the proper control and optimized performance of the system. Proper program settings are more relevant than with
induction motors. Nameplate data provided with each motor should be used to ensure proper setup and of the ABB Drive to
control the motor.
One of the most significant difference of PM motors is rotor structure. The figure below compares the rotor design of a
standard surface mount PM motor versus the EC Titanium FASR design.

Typically, the Motor torque is in direct relation to the current. Motor speed is in direct relation to the output frequency of the
converter. Motor output voltage also called back-EMF is directly proportional to speed of the motor.
As the back-EMF of the motor increases with speed, there is a risk of damaging the frequency converter if the drive coasts
to stop or trips at a high speed. Therefore, the speed of a FASR Motor is limited by the drive so that the back-EMF would
not charge the DC link above the trip limit. This internal limit is a safety precaution, and it cannot be disabled by the user
parameters.
