Operating parameters

The counting direction can be defined by the operation parameter, which determines the counting direction and whether the output code increases or decreases.

Single-circle resolution

The resolution parameter can be programmed, and the resolution per revolution can be set as needed.

Total resolution

This parameter value corresponds to the position value corresponding to the entire measurement length. It cannot exceed the total resolution of the absolute encoder. In the normal mode, the settable value can only be a multiple of 2.

Preset value

This function is used to set the actual value of the absolute encoder to the desired position value.

Limit switch, minimum/maximum

Two positions can be programmed. If the measured value exceeds the range between these two values, the encoder will raise one of the 32 positions.

Programmable transmission mode

Query mode

The host acquires the current position data by remotely transmitting communication instructions. The absolute encoder reads out the current position, calculates based on the set parameters, and then communicates Return the actual value through the same CAN recognition unit.

Circular mode

The absolute encoder cyclically transmits the current actual value without the need for instructions from the host. This cycle time can be programmed and rewritten, ranging from 1 to 65536ms Between, at the millisecond level.

Synchronous mode

After the controller receives the synchronization signal, the encoder starts to transmit the current actual value. If multiple nodes respond to the synchronization signal, each node responds one by one according to the CAN identifier. Without a programmable compensation time, the synchronization counter can be programmed until a definite number of synchronization signals is reached The coder just transmits.

When setting, remove the two screws to open the connecting cap.

There are two leds on the back of the connecting cap, which can display the status of the device. It is very helpful when installing and setting up the encoder.

Node address
Node Settings are accomplished by two knob switches in the connection cap. The address range is from 0 to 89, and each address can only be assigned once. The node address number defined internally by the encoder is automatically increased by 1.
Terminal resistor
The terminal resistor RT(120Ω) is integrated in the connection cap. If the encoder is connected to the end of the bus or the starting end, the terminal resistor must be turned on.

Settings

Electrical interface

The factory standard configuration of the encoder is as follows: the node address is 32, the baud rate is 20KBaud, and the data transmission cycle time is 0ms(i.e., no cycle). For different applications, customers can make Settings using SDO messages. The effective baud rate ranges from 20kBaud to 1MBaud, the node number is from 0 to 89, and the cycle time is from 1ms to 65536ms.
Note: The encoder will automatically add 1 to the set node address number inside.

The absolute rotary encoder with cable and plug interfaces is designed in accordance with the standardized CiADR303-1 cable and plug protocol. There are various electrical connection methods available, such as a 5-pin M12 plug. Encoders can be connected in the following ways:
-5-pin M12 male plug and a 5-pin female plug
-5-pin M12 plug and exhaust hole
-9-pin D-Sub plug or cable outlet (not applicable to the heavy-duty version)

Install the connecting cap

The rotary encoder is connected to two or three cables, depending on whether the power supply is integrated into the bus cable or connected separately. If the power supply is integrated into the bus cable, the cable sealing sleeve therein can be installed through a plug. Cable sealing sleeves are suitable for cables with diameters ranging from 6.5 to 9mm.
