Commissioning With Speed Sensor - Siemens SIWAREX WP241 Manual

Figure 7-3
Enter your total belt length. Note that your result will be all the more accurate if you can enter
the belt length exactly. Decide in the next step on a speed detection method matching your
system. The number of belt revolutions is important for dynamic commands such as zeroing.
If the parameter is set to 2, for example, the electronics averages the load cell signal over
two complete revolutions and only then carries out the actual calibration/zero setting
command. The "Warm-up time" parameter is specified in minutes. An information bit is then
available in the scale status which remains TRUE for the defined time. The bit is for
information only; it has no effect on other functions. It can be used, for example, to allow the
belt to warm up before transportation of material is started. Using simulation mode you can
activate the "Load simulation" and "Speed simulation" functions. Without this activation, the
scale cannot be switched to the respective simulation mode.

Commissioning with speed sensor

When using a speed sensor, use the standard setting "Speed sensor on digital input DI.0" in
the speed detection parameter.
Enter the remaining parameters appropriate to your application, and confirm them using the
save button. Further information on the individual parameters can be found in chapter →
Scale parameters and functions of the belt scale (Page 69). When using the speed sensor,
the "Nominal belt speed" parameter is only used as a reference for the speed limits.
Use the "Door symbol" at the bottom left to return to the Setup menu. In the next step,
calibrate your scale using the instructions and parameters under item "1.2 Calibration".
