11.4.1. High Resolution Speed Reference
This register allows the user to set the speed reference value in the internal format, e.g. 3000 = 50.0Hz. This allows control resolution
to 1 RPM with a 2-pole motor. The maximum allowed value is limited by P-01.
Either register 2 or register 5 can be used for speed reference control, however only one reference should be used in any control
system, otherwise unexpected behaviour can result.
11.4.2. Scope Channel Data Values
These registers show the scope present data sample value for the first two scope channels. The channel data source selection is
carried out through Optitools Studio.
11.4.3. Modbus RTU Registers 25 - 28: Drive Serial Number
The drive serial number may be read using these four registers. The serial number has 1 1 digits, stored as follows:
Register 28
x x x
e.g.
Register 25
Register 26
Register 27
Register 28
Drive Serial Number 5
11.4.4. Parameter Checksum Modbus Register 46
A checksum is calculated based on the present value of all user adjustable parameters and stored in Modbus Register 46. This may
be read to determine if parameter settings have been adjusted.
