2.2.3. Status Update Request
A Status Update Request will cause the drive to report its current operating status. The status
codes, descriptions and associated alarms are shown in the chart below.
The Device Status Code consists of two parts. The Least Significant Byte, (LSB) of the hex number
is the Alarm Number. The Most Significant Byte (MSB) indicates if the alarm is a normal trip (01)
that can be reset automatically or manually, or if the alarm is a trip lock (02) requiring cycling
power to the drive.
