Drive Registers
9.1
Data Internal vs. Display Representation
Register data passed across the Modbus communications link is always in INTERNAL units, although the drive itself
may show the information in some alternate DISPLAY units.
For register values with 1 or more decimal places, the actual value sent over the Modbus communications will be
the value times 10
DP
, where DP is the number of decimal places.
Example
An actual frequency of 34.3Hz would be sent over the network as 343 (34.3*10
1
).
If the drive is setup to display the actual frequency in RPM using P178 = 29.17, the actual speed would be displayed
on the drive as 1000 (RPM) but would still be sent over the Modbus communications as 343 (or 01 57 hex).

Drive Control Registers
Table 5 describes the SMV Drive Con trol Registers in ascending order of SMV Register #. Registers #1 through #99
are reserved for configuration and control over the network and cannot be accessed via the drive’s local keypad.
