Description
Displays a count of packets with a CRC error received by the
drive. An increasing count indicates interference on the bus.
Can be reset from the control panel by keeping Reset
depressed for over 3 seconds.
Number of CRC errors.
Selects how the drive reacts to an EFB communication break.
Changes to this parameter take effect after the control unit is
rebooted or the new settings validated by parameter
