  • Page 4: Device Description

    Device description Device description The VLM60 is a sensor for detecting the speed of moving objects and measuring the length. It is intended for use in industrial environments. The measuring principle is based on a correlation method. Even the slightest movements can be detected in this way.

    0°. The maximum permissible tolerance of these two angles is ±2°. Since the VLM60 can measure velocity in both the X-direction and the Y-direction, the yaw angle is arbitrary. It should be noted that the velocities are recorded with a sign. It is recommended to mount the device with a yaw angle of 0°...

  • Page 6: Connections

    The D-coded, 4-pole flange socket (connection 2) is the connection for the optional fieldbus interface. The connection is led out if the VLM60 is equipped with a fieldbus interface ex works. Otherwise, a blind plug is located there. The USB programming connector (connector 3) is an A-coded, 5-pin flange socket. The pin assignment is shown in the following two tables.
  • Page 7 Connection 1 is a combined supply/signal connection. According to the applied EMC test standard it follows that the DC power supply for the VLM60 must be designed locally. The device must not be connected to a DC distribution network! It is the user's responsibility to establish the cabling accordingly.
  • Page 8 GND, e.g. 1.2 kOhm for a current of 20 mA at 24 V supply voltage. Fieldbus interface (Connection 2) The VLM60 optionally can be equipped with an additional fieldbus interface. This is done ex works. For subsequent installation, the device must be sent to the manufacturer. An additional board is installed inside the device and a device flange at connection 2.

    In addition to the transmission of the measured speed, the recorded lengths can also be transferred. Furthermore, it is possible to trigger measurements in the VLM60 with the help of a control byte. Furthermore, VLM60 parameters can be set via the bus.

  • Page 11: Parameterization

    4.1 Command input and VLMTool The parameterization or command input can be done with any terminal program (e.g. HTerm). For parameterization of the VLM60, connection 3 is connected to a USB interface of a Windows PC via a programming cable..

  • Page 12: Parameter

    Parameterization 4.2 Parameter The following overview contains all parameters available in the VLM60. The first line describes the parameter in each case. The second line shows the syntax, the permitted value range and the default setting (ex works). In the third line, if necessary, remarks to the respective parameter are noted.
  • Page 13 Parameterization VLM60 User Manual Holdtime Serves to set a time period in which the last detected velocity value continues to be output on the pulse output. After that, zero is output. holdtime [n] n = 10 ... 65535 (unit: ms)
  • Page 14 VLM60 User Manual Parameterization PO1Sync Serves to set output frequency of the first pulse output. po1sync [n] n = 0, 1 default: 0 average-synchronous. The update is synchronous with the duration of the speed averaging (Parameter Average). trigger-synchronous. The update is synchronous with the clock at the switching input (TRIGGER).
  • Page 15 This parameter influences the behavior of the primary sensor. Changes should only be made in consultation with the manufacturer. Silent Serves to set the behavior of the VLM60 command line (terminal). It can be set whether the entered command is sent back to the terminal (echo) or not. silent [n]...
  • Page 16 VLM60 User Manual Parameterization SO1FORMAT The S1 programming interface can be used not only for parameterization but also for data output. The transmission format can be specified within wide limits with this parameter. The output takes place as ASCII characters. The individual switches can be separated by space, comma or point. However, the separators between the parameters can also be omitted.

  • Page 19 Serves to set angle specifications corresponding to the inclination/rotation of the mounting position of the VLM60. For better reflection of the surface contrasts, a correction of the mounting position may be necessary. This angle correction only applies to flat measuring surfaces! tilt [f1] [f2] f1 = 1.000 ...

  • Page 20: Additional Commands

    VLM60 User Manual Parameterization Window Serves to set the size of the ring buffer for the moving average of the velocity. This parameter is intended for highly dynamic speed measurements in the production process and for control tasks. One ring buffer element corresponds to the time length of the parameter Average.
  • Page 21 When the device is started, this information is output automatically. Number The VLM60 has an internal object counter. The count is always incremented when a length measurement is completed. If the device is restarted, the counter falls back to zero. With this command, the counter status can be queried as well as set.
  • Page 22 If such a case occurs, the manufacturer must be contacted. The command is used to insert comment lines in parameter files, which can be sent to the VLM60 for easy parameterization. All characters after REM in the same line are ignored.
  • Page 23 Parameterization VLM60 User Manual Serves to display the serial channel (S1 or S2) via which the communication between the VLM60 and the connected PC is currently taking place. Simulation The command is used to simulate velocity and measuring rate at the pulse outputs of the measuring device.

  • Page 25 For the update of the fieldbus interface, in addition to the VLMTool, the program "Wingate" from the company Deutschmann Automation GmbH & Co. KG is required. By calling "update f" the VLM60 is set to establish a direct communication channel between the fieldbus module inside the VLM60 and the connected PC. The VLMTool automatically terminates the communication with the VLM, which is then taken over by Wingate.
