Page 18: Profile Overview
PROFIBUS USER MANUAL Leine & Linde AB 4 Profile overview Encoder Profile for DPV0, version 1.1, Order no 3.062. The operating functions in this profile are divided into two device classes named Class 1 and Class 2. Class 1 encoders offer basic functions that all PROFIBUS-DP encoders must support. -
Page 19: Dpv0 Encoder Classes
PROFIBUS USER MANUAL Leine & Linde AB 4.1 DPV0 encoder classes The device can be configured as a class 1 or class 2 PROFIBUS slave device.

Page 21: Parameterization, Dpv0
PROFIBUS USER MANUAL Leine & Linde AB 5.4 Parameterization, DPV0 The PROFIBUS-DPV0 device is parameterized by means of the operating parameters. The values selected in the configuration tool are saved in the DP master and are transferred to the PROFIBUS-DP slave each time the network is started. The following table lists all available parameters: Parameters Data type... -
Page 22: Class 2 Functionality
PROFIBUS USER MANUAL Leine & Linde AB 5.4.2 Class 2 functionality This bit enables or disables class 2 functionality. The Class 2 functionality bit for PROFIBUS-DP devices is by default disabled (0). This means that this control bit must be activated during parameterization in order to support the class 2 functions. Note: If a class 1 device uses some optional class 2 functions, the class 2 control bit must be set. -
Page 23: Measuring Units Per Revolution
PROFIBUS USER MANUAL Leine & Linde AB 5.4.5 Measuring units per revolution The total measuring range is calculated by multiplying the singleturn resolution with the number of distinguishable revolutions. The default settings for multiturn encoders RXA 607 are: Measuring units per revolution= 8192 Total measuring range in measuring units= 8192 The default settings for multiturn encoders RXA 608 are: Measuring units per revolution= 8192... -
Page 24: Total Measuring Range (Units)
PROFIBUS USER MANUAL Leine & Linde AB 5.4.6 Total measuring range (units) The total measuring range is defined by the parameter "Total measuring range in measuring units." The device has two different operating modes, depending on the specified measuring range. When the device receives a parameter message, it checks the scaling parameters if a binary scaling can be used. -
Page 25: Picture 15 Non-Cyclic Scaling
PROFIBUS USER MANUAL Leine & Linde AB B. Non-cyclic operation If the measuring range is used to limit the encoder value range to a value not equal to the specified singleturn resolution * 2 , the output position value is limited within the operating range. -
Page 26: Velocity Control
PROFIBUS USER MANUAL Leine & Linde AB 5.4.7 Velocity control The velocity data can be accessed if class 2 32-bit + velocity configuration is used. In this case the input data consists of 32-position data plus 16-bit signed velocity data. The input velocity value is negative in CCW direction if code sequence is set to CW. -
Page 27: Data Transfer In Normal Operation (Ddlm_Data_Exchange)
PROFIBUS USER MANUAL Leine & Linde AB 5.5 Data transfer in normal operation (DDLM_Data_Exchange) The DDLM_Data_Exchange mode is the normal status of the device when operated. In this mode the position value is transmitted from the device in a cyclic manner. Output data can also be sent to the device i.e. -
Page 28: Preset Function
PROFIBUS USER MANUAL Leine & Linde AB 5.5.2 Preset function The preset function enables adaptation of the position value from the encoder to a known mechanical reference point of the system. The preset function sets the actual position of the encoder to zero or to the selected preset value. The preset value is written to the encoder as output data in the Data_Exchange function. -
