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).
9.2
Configuration and Control Registers
Registers #1 through #99 are reserved for configuration and control over the network and
cannot be accessed via the drive’s local keypad.
