Product Range

The AC supplied 890SD Standalone Drive is designed to control standard 3-phase ac induction motors, or
to be used as an active front-end input section.
These larger models are available in a range of ratings for constant torque and quadratic torque applications.
This dual mode feature provides a cost effective solution to general industrial applications, as well as the
control of pumps and fans.
 The unit can be controlled remotely using configurable analogue and digital inputs and outputs,
requiring no optional equipment.
 Controlling the unit locally using the 6901 Keypad, or remotely using the DSE 890 Configuration Tool
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.
 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.
