AC Servo motor + drive 400 watt-1000 watt with Can or modbus TCP bus interface

MODBUS range actuators equips a Modbus board which supports the communication protocol of Modbus TCP/IP . The Modbus board makes use of RJ45 interface and can operate in 4 wire mode, and supports baud rates up to 38.4 kBit/s. Master and slave devices: Max. 247 slave devices connected to one bus, withoutrepeaters max. 32 slave devices. 

If the security is required highly for the environment,a redundant connection between the actuators and the DCS can be established by using a second fieldbus cable. And two Modbus boards must be equipped in the actuator, respectively corresponding to bus highway1 and bus highway2. In this way, the communication can be swich to highway2 at once when the highway1 happen trouble.

Modbu master can send the commands which make the actuator carry out OPEN, CLOSE, STOP and ESD.The master can also read the status , setting parameter and some alarm information.

3.1 Local electric Operation

There are two knobs on the electric cover of the actuator: one Selector knob and one operator knob. For local inching operation, please switch the “Selector” knob to “LOCAL” position and then use the “Operator Knob” to control the actuator.

3.1.1 Inching

Turn and hold the “Operator Knob” to “CLOSE” position and the actuator moves in the closing

direction. Once released, the knob will automatically return to its original position and the actuator

movement stops.

Turn and hold the “Operator Knob” to “OPEN” position and the actuator moves in the opening direction.

Once released, the knob will automatically return to its original position and the actuator movement stops.

3.1.2 Keep

Turn the “Operator Knob” to “CLOSE” position, and the actuator moves in the closing direction. Then release the knob, and the knob will automatically return to its original position, however the actuator continues its movement in the closing direction until the action stop conditions are met (such as over torque or close limit, etc.)

Turn the “Operator Knob” to “OPEN” position, and the actuator moves in the opening direction. Then

release the knob, and the knob will automatically return to its original position, however the actuator

continues its movement in the opening direction until the action stop conditions are met (such as over torque

or open limit, etc.)

3.2 Local Stop

When Selector knob is at “STOP” position, the actuator will disable all inching operations.

3.3 Remote Operation

3.3.1 Remote Switching Value Control

Conditions for enabling remote switching value control:

1. Selector knob is at “Remote” position;

and 2. Manual/Auto switch is open.

 

3.3.2 Remote Automatic Control

Conditions for enabling remote modulating control:

1. Selector knob is at “Remote” position;

and 2. Manual/Auto switch is closed
