p Encoders with EnDat interface:
 The form displays the electronic ID label of the connected encoder:
Transmission format, signal periods, measuring steps,
distinguishable revolutions, ID number and serial number.

Only for encoders with EnDat 2.2 interface: The DIAGNOSIS soft
key opens a form showing the function reserve of the encoder:
 Incremental track (INC)
 Absolute track (ABS)
 Position value calculation
 Press the ALARMS soft key to display the alarms that are supported
by the connected encoder, and to show whether errors have
occurred. A color-filled square before the respective alarm indicates
the status:
 Gray means that the alarm is not supported by the connected
encoder.
 Green
means that the alarm is supported by the connected
encoder, and no error has occurred yet.
 Red
signalizes that an error has occurred.
 Press the WARNINGS soft key to display the warnings that are
supported by the connected encoder, and to check whether
warnings have occurred. A color-filled square before the respective
warning indicates the status:
 Gray means that the warning is not supported by the connected
encoder.
 Green means that the warning is supported by the connected
encoder, and no warning has occurred yet.
 Red signalizes that a warning has occurred.
