Product Range

The AC890PX AC Drive is designed to control 3-phase induction or permanent magnet AC
motors, or to be used as an active front-end.
Designed as a free-standing drive, the AC890PX comprises removable modules housed in a tall
cabinet.
It is available in a range of ratings for constant torque and variable torque applications. This
dual mode feature provides a cost effective solution to general industrial applications, as well
as the control of pumps and fans.
 Supplied as a top or bottom wire entry version.
 Local control is achieved using the Keypad.
 Remote control is via the DSE 890 Configuration Tool. This gives access to parameters,
diagnostic messages, trip settings and full application programming. Other features also
become available, such as the advanced sensorless vector control scheme which gives high
torque, low speed operation; and a unique Quiet Pattern control system that minimises
audible noise from the motor.
 The unit can also be controlled remotely using configurable analogue and digital inputs and
outputs, requiring no optional equipment.
 Option Cards can be fitted to the drive to give serial communications, closed loop speed
control, and the factory-fitted dynamic braking functions.
IMPORTANT Motors used must be suitable for inverter duty.
NOTE
Do not attempt to control motors whose rated current is less than 25% of the drive rated
current. Poor motor control or Autotune problems may result if you do so.
