Initialization Of Motor Constants In Mode-B - Amtech Axpert-Eazy Series Instruction Manual

(9) Always correctly install the front cover and outer cover before turning the power ON.
(10) When using the IM vector control with speed sensor mode, make sure that the encoder signal
cable is correctly connected to the control card terminal.
(11) Assign an operator, and make sure that the operator operates the switches.
Make sure that there is no abnormal noise, smoke or odors at this time. If any abnormality is found,
turn the power OFF immediately.
4-1-1 Selection of control modes
With the Axpert-Eazy, Eight control modes can be selected. These are set with the parameter 'A401:
Control mode'.
Sets the motor control mode of operation.

4-1-2 Selection of start control
The Axpert-Eazy AC Drive can be controlled from various places like Digital Operation Panel (Local),
Terminal or from PC. Select appropriate start control in A301. Use Digital Operation Panel (Local)
during the test operation.
A301: Start Control
=1: Local
=2: Terminal
=3: Serial
4-1-3 Selection of frequency reference input
The Axpert-Eazy AC Drive accepts frequency reference from various places like Digital Operation
Panel (Local), Terminal or from PC. Select appropriate frequency reference input in A106. Use Digital
Operation Panel (Local) during the test operation.
A106: Frequency Reference Input
=1: Local (Digital Operation Panel)
=3: FSI 4-20mA
=5: FSI 0-20mA
=7: FSI 20-4mA
=9: FSI 20-0mA
=11: Serial
=13: VIN 0-10V
=15: PLC Analog output-1
=17: PLC Analog output-3
Refer the diagram of selection process of frequency reference diagram for the better understanding of
the flow frequency reference signal priorities.

4-2 Initialization of motor constants in Mode-B

Input the motor rating parameters. Set the following parameters in Mode-B.
B101: Rated Input Voltage (V)
B102: Motor Voltage (V)
B103: Motor Current (A)
Axpert-Eazy AC Variable Frequency Drive
Explanation
The voltage frequency ratio is controlled.
The voltage frequency ratio is controlled.
The IM is vector-controlled without a speed sensor.
The speed can be controlled.
The IM is vector-controlled with a speed sensor.
This mode is used when a fast speed response or
torque response is required.
