3—DRIVE MENU

This menu is accessible when the access locking switch is in the

position. The parameters can only be modified when the motor is

stopped.

Optimal performance is obtained:

• By ensuring the input frequency selection switch is properly set (see

page 13)

• By entering the motor nameplate values into the Drive menu

parameters

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

page 40 for more information concerning the autotune function (tUn).

Parallel, Undersized, and Special Motor Applications

The ATV58 drive controller can be used in motor applications with

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

motors. Follow the configuration steps below.

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

macro-configuration (see page 21).

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

Yes or PSM (see page 44).

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

to obtain satisfactory performance (see pages 32 and 34).

Parallel motor applications contain multiple motors wired in parallel to the

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

Product Data Bulletin SC100R5/95, for additional application 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 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 39 shows the parameters accessed in the Drive menu.
