Peak Speed Capture The XM-123 retains the value of the highest
speed observed since module power was
cycled or the “peak speed” value was
manually reset.
Non-Volatile Configuration A copy of the module configuration is
retained in non-volatile memory from where
it is loaded upon power up*.
*The configuration stored in non-volatile
memory can be deleted only by a command
sent via the serial interface, using the Serial
Configuration Utility, or via DeviceNet from any
compliant software application.
Accuracy (minimum) ±1% of full scale range for the channel
±1% of alarm setpoint for speed
