Preface
Thank you for purchasing the MD290 series AC drive developed by Inovance.
It is a general-purpose AC drive mainly used for controlling and adjusting the speed and
torque of three-phase AC asynchronous motors. MD290 provides user-programmable
features and software tool monitoring and communication bus functions, delivering
rich and powerful combined functions and stable performance. It can be used to drive
textile, papermaking, drawing, machine tools, packaging, foods, fans, water pumps and
other automated production equipment.

■Adjusting drive parameters
The drive when it leaves the factory with default settings should enable the user to get
started quickly to check on the basic mechanical running conditions. At a later time,
󶍾ne tuning to optimize the operation/performance can be undertaken.
Such parameter tuning should be done by quali󶍾ed personnel who have prior training
on Servo Drives. Some parameter settings can have adverse reactions if manipulated
incorrectly and care should be taken especially during the commissioning startup
stages to prevent personnel from engaging the machine.
This user guide provides a complete list of the parameters with functional description
and care should always be taken whenever parameters are adjusted during a live
running startup. Inovance and Authorized Distributors can provide product training and
if in doubt seek advice.
