Optimal performance is obtained:

• By ensuring that the input frequency selection switch is properly

set (see page 14)

• By entering the motor nameplate values into the Drive menu

parameters

• By initiating an autotune (on a standard asynchronous motor).

See page 45 for more information concerning the autotune

function (tUn).

Parallel, Undersized, and Special Motor Applications

The ATV58 TRX drive controller can be used in applications with

multiple motors wired in parallel, undersized motors, or with special

motors. To configure the drive controller for these applications, follow

these steps:

1. Select either the “Hdg: Material Handling” or “GEn: General Use”

macro-configuration (see page 23).

2. Configure the Special Motor parameter (SPC) in the Drive menu

to Yes or PSM (see page 50).

3. Adjust the IR Compensation parameter (UFr) in the 2—Adjust

menu to obtain satisfactory performance (see pages 35 and 37).

Parallel motor applications consist of multiple motors wired in parallel

to the output of one drive controller. Refer to the Square D Application

Guide, Product Data Bulletin SC100R5/95, available at

www. SquareD.com for information on properly sizing the drive

controller for parallel motor applications.

An undersized motor is defined as a motor with a full current rating is

less than 25% of the ATV58 TRX drive controller rating. Select PSM

in the Special Motor menu.

Synchronous permanent magnet, synchronous would field, and

synchronous reluctance motors are examples of special motors.

Table 11 on page 43 shows the parameters accessed in the Drive

menu.
