890SD Standalone Drive

Set-up using 4Q Regen Active Front End (AFE) control mode.

Refer to Chapter 7 to correctly set-up the drive for an 890CD/SD 4-Q Regen

AFE Application.

Autotune is not required.

Set-up using PMAC (Permanent Magnet AC) servo or torque motor control

mode - a high performance application where the drive uses Resolver or

Sin/Cos Encoder motor feedback.

In this mode, speed feedback signals from the motor shaft encoder are

processed to determine the rotational speed of the shaft. A PI algorithm within

the software uses this information to produce varying gate drive signals to the

drive circuits. These signals cause the drive to output the required voltage and

frequency for a particular motor speed.

Autotune is not required.

The Motor Selection Wizard in the 890 DSE Configuration Tool MUST be

used to correctly set-up the motor and feedback device parameters. Failure to

do so may result in damage to the servo motor.
