EM303A is a general purpose inverter (Speed Sensorless Vector Control). It helps an
induction motor to achieve not only the speed regulation standard of a DC motor, but also
the control ability of a torque motor, and the motion control system is optimized with
quick response, precise control and system stability.
The updates of EM303A:
1. Support Modbus RTU standard communication protocol.
2. Support RS485 master-slave communication control mode, numeric synchronized
control achieved.
3. Numeric input terminals support F/R logic control, delay input control, and etc.
4. Numeric output terminals support PWL/pulse output, F/R logic output and delay output,
and etc.
5. Analog input signals VS/IS/VF/IF can be programmed as numeric inputs, numeric
terminals expansion control achieved.
6. With filtering, analog input signals VP/VS/IS/VF/IF can actively avoid analog signals
interference and drift.
7. User can easily define the display of function code menus.
8. Run, stop and parameters setting status can program the displayed parameters
independently.
It is the duty of any user to perform the appropriate, correct installation or configuration
of the optional parameters of the devices. Neither SINEE nor its distributors shall be
responsible or liable for misuse of the information contained herein or mismatching the
inverter with the motor.
In the interests of commitment to a policy of continuous development and improvement,
SINEE reserves the right to update the specification of the product or its performance, or
