Control Modes
4-Q
4-Q REGEN
Set-up using 4Q Regen Active Front End (AFE) control mode.
Refer to Chapter 8 4Q REGEN NOTE to correctly set-up the drive for an AFE
application.
Autotune is not required.
PMAC
PMAC
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.
Use 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.
