9.4 Reference value / actual value
The control gives its reference value to the frequency inverter via the object 0x6042/0
target velocity in the RxPDO used and receives the information about its actual value
back via the object 0x6044/0 control effort in the TxPDO used.
The use of the reference/actual value channel depends on the set configuration
(control system). The actual value is generated from the correct source depending on
the control system used.
Note: The reference value in the object 0x6042/0 target velocity and the actual
value in the object 0x6044/0 control effort are interpreted by the control
in the notation xxxx RPM. Conversion into a frequency (reference value)
or from a frequency (actual value) is done in the frequency inverter.
The object pole number is converted inside the product and related to the
parameter
No. of pole pairs 373 in the first data set. The paramete
r
value of the number of pole pairs is to be doubled for the ob
ject
0x604D/0 pole number.
The reference value for the frequency inverter from the object 0x6042/0 target
velocity is included via the reference line value. This reference value is combined with
the internal reference value from the reference frequency value channel in the input
of the ramp function. Reference frequency value channel: see operating instructions.
