In parameter P546, the function of the 1. setpoint is set. The following
possibilities are available:
By default, the command frequency is transmitted as a 16 bit value in
setpoint 1. Setpoint 1 is transmitted to the converter in the job telegram in
the process data section as the second word.
PCD 1 PCD 2 PCD 3 PCD 4
CTW SP1 SP3 SP2
Fig. 15-16: Setpoint 1
The setpoint is transmitted as an integer figure with the value range -
32768 to 32767 (8000 hex to 7FFF hex). The value 16384 (4000 hex)
corresponds to 100%. The value C000 HEX corresponds to -100%. A
setpoint value of 100% corresponds to the parameter
maximum
frequency (parameter P105) set in the same parameter record.
If PPO type 2 or 4 is used, a 2. setpoint can be transmitted in word PCD4,
and a 3. setpoint in PCD3, both in addition to setpoint 1.
PCD1 PCD2 PCD3 PCD4
CTW SP1 SP3 SP2
A third setpoint can only be transmitted if no 32 bit setpoint is transmitted
in the first setpoint.
PCD1 PCD2 PCD3 PCD4
CTW SP1 SP2
The second and third setpoint is always 16 bits wide. The function of the
second and third setpoint can be set in the converter under the parameter
P547
'Function setpoint 2' or P548 'Function setpoint 3'.
The first two setpoints are transmitted as integer figures in the range (-
32768 to 32767). The value 16384 (4000 hex) corresponds to 100%. The
value C000 HEX corresponds to -100%; thus, no setpoints in the range
-200% to +200% can be transmitted. Here, a setpoint of 100%
corresponds to the respective rated quantity:
