By default, the actual frequency - i.e. the actual output frequency of the
converter- is transferred as a 16 bit value in actual value 1. In the
converter response telegram, the actual value 1 is transmitted as the
second word to the master in the section of the process data.

Fig. 15-18: Actual value
Actual value 1 is transmitted as integer figures in the range (-32768 to
32767). In addition to the actual frequency, other current converter values
can be transmitted. The setting is made in P543,
'Function actual value 1'.
The settings 'Actual frequency', 'Actual speed', 'Current' and 'Torque
current' are transmitted as a percentage of the respective rated quantity.
The value 16384 (4000 hex) corresponds to 100%. The value C000 HEX
corresponds to -100%. Actual values in the range -200% to +200% can
be transmitted.
The setting "Status digital I/O" (P543 = 5) transmits the status of the
control terminals and the relays (multi-function relays:

When PPO type 2 or 4 is used in a transmission, two more actual values
can be transmitted to the control.
Actual value 2 (AV2) is sent in PCD4. The value to be transmitted can be
selected in P544 (actual bus value 2). The actual value 3 (AV3) can be
sent in PCD3 if actual value 1 is
not a 32bit value. The value to be
transmitted can be selected in P545 (actual bus value 3). The scalings
correspond to those of actual value 1.
