Fig. 41 Setting The Measuring Range Via Index 0Xf800:11 "Range - Beckhoff EtherCAT EP3752-0000 Manual

Measuring range
The measuring range can be selected in index 0xF800:11 "Range".
Fig. 41: Setting the measuring range via index 0xF800:11 "Range"
When selecting "Channel setting" in index 0xF800:11, the measuring range is set individually for each
sensor:
• Measuring range for sensor 1: Index 0x8000:19 "Range"
• Measuring range for sensor 2: Index 0x8030:19 "Range"
This setting applies to all axes of the respective sensor. An individual setting for individual axes is not
possible.
Sampling rate and synchronization modes
The sampling rate depends on whether the box's filters are activated. The filters are deactivated by default.
They are described in the chapter Filter [} 42].
• The box operates SM-synchronously
if no filters are active. In this mode the EtherCAT cycle time determines the sampling rate: The
measured values are read from the sensors in each EtherCAT cycle.
The sensor operates internally with 10-bit resolution up to a cycle time of 1 ms. Below that the
resolution is reduced to 8-bit. The minimum cycle time is 200 µs.
• If at least one filter is active,
the box runs in free run with a sampling rate set by CoE index 0xF800:0D "Filter sampling rate".
The resolution is reduced to 8-bit if the sampling rate is increased to 2500 Hz or 5000 Hz.
