Table 2.1: Reference/feedback values
The reference/feedback value is the percentage of the range
of parameter 3-02 and 3-03. Values within the ranges 100% to
200% and -200% to -100% applies only to the reference. The
Float representation of the value 200% must be limited to
maximum 32767 and minimum -32768.
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 Signif-
icant 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.

Read/write notes
A write command to an ADF (Internal Floating Point) or BD
(Internal Byte) point type will be stored in the drive's EEPROM.
NOTE
If write command is issued to an overridden point, the
new value will not be stored in the drive's EEPROM.
