Encoder Parameter Settings

Select “Device view”→select “Device overview”→Right click on the “FRABA 2.2 Multiturn”→ “General”→“Devicespecific parameters”, encoder parameter setting: 
1.Code sequence
2.Desired measuring units
3.Revolution
4.Total measuring range
5.Lower/Upper limit switch: disable by default.

Program Blocks

Network 1: Encoder Position Value Output

1. Encoder output value Bit0-Bit24: position value
2. Encoder output value bit25-bit31: status value
3. When reading the position value, the state value "bit25-bit31" should be cleared by using 
logical operation, and the program section is shown as left:
Note: first enter the address bit, such as ID68, MD100, then modify the variable name

Network 2: Encoder Speed Value Input

Network 3: Preset Order

Network 4: Reset Order

Network 5: Status Bit Reading

Watch and Force Table

Compile

1. Right-click PLC→ select "compile" → select "hardware and software (only changes)".
2. Check that the hardware and software configuration Settings are correct.

Download Configuration to PLC

1. Click the download button.
2. Begin your search.
3. Select the corresponding PLC.
4. Click download.
5. Click "all started" after downloading.

Watch and Force

1.After switching to online, observe the parameters of each variable.
2. Changing “Preset button“  the value to 1 and then the current position value is set to 0. After activation, changing “Reset button”  to 1 and activate, and then can preset again.
3. "Velocity output unit" should be the same as the parameters set in Page 12.
4. "step distance unit" shall be set with the actual distance unit
