Table 2 Column Denitions
Access: RO = Read Only access; RW = Read/Write access
Index: The CAN address that is used to access this parameter.
Sub-index: Some parameters have several values associated with them. In these
cases, a Sub-index is used to access each part of the parameter.
Range, CAN Value, and Resolution:
The Range is the natural value (volts, amps, hours) that we think of
when adjusting the settings. Settings will be in tenths, hundredths, or
thousandths, as applicable. Examples:
10.3 volts = 103 (in tenths of a volt)
2.01 amps = 201 (in hundredths of an amp)
10.5% = 105 (in tenths of a percent)
0.025 sec = 25 (in milliseconds, thousandths of a second)
65000 hrs = 65000 (no scaling on time)
The CAN Value is the actual value that must be written or is read over
the CAN bus. The CAN Value is stated on the second line (in italics)
and provides the equivalent data value that must be sent to archive the
setting desired. For example, to set the Heartbeat Rate to 1 second, a
value of 1000 must be sent.
The Resolution (if present) provides the step-size for the CAN values.
For example, the Heartbeat Rate cannot be set to 1.003 seconds (CAN
value of 1003) because it has a resolution of 4. If a Heartbeat Rate of
803 is sent to the eXm, the eXm will truncate and write the value 800
internally and respond with an SDO Acknowledge of 800 (the value
written with a even step size of 4).
