In the Master software:
1. Set the Control Word value to 0hex.
2. Set the Control Word value to 47Ehex.
3. Set the Control Word value to 47Fhex.
4. AC drive status is “RUN”.
5. Set the Reference value to '2000Hex' (=50.00%).
6. Actual speed is 2000Hex (25.00 Hz if MinFreq is 0.00 Hz and MaxFreq is 50.00 Hz)
7. Set the Control Word value to 47Ehex.
8. AC drive status is “STOP”.

Significance
Data type
Explanation
915
Selection switch for DO IO
Data in the setpoint tele-
gram
Array[n]
Unsigned16
Describes the data in the setpoint tele-
gram. The parameter is an array of sig-
nals' numbers that creates the setpoint
telegram.
916
Selection switch for DO IO
Data in the actual value
telegram
Array[n]
Unsigned16
Describes the data in the actual value
telegram. The parameter is an array of
signals' numbers that creates the
actual value telegram.
922
Telegram selection
Unsigned16
Currently selected standard telegram is
read. It returns for example 1 for ST1.
See chapter 8.3.1 for possible values.
923
List of all parameters for
signals
Array[n]
Unsigned16
The parameter is an array. The index of
the array indicates for a signal number
and its value for corresponding parame-
ter number.
Not supported standard signals, those
in range 1-99, have values set to 0. Gaps
between the device-specific signals are
also filled with 0.
Refer to Table 73.
930
Operating mode
Unsigned16
1 = Speed control mode
944
Fault message counter
Unsigned16
The fault message counter is incre-
mented each time that the fault buffer
changes. This means that it is guaran-
teed that the fault buffer is consistently
read-out. Without this parameter, it is
not guaranteed that the fault buffer
does not change while reading-out.
