Parameter list
p2000 Reference speed reference frequency / Ref_n Ref_f
VECTOR Can be changed: T
Data type: Floating Point
P-Group: Communication
Min
6.00 [1/min]
Description: Sets the reference quantity for speed/velocity and frequency.
All speeds/velocities or frequencies specified as relative value are referred to this reference quantity.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
The following applies: Reference frequency (in Hz) = reference speed/velocity (in (RPM) / 60)
Dependency: Refer to: p2001, p2002, p2003, r2004
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
Example 1:
The signal of an analog input (e.g. r4055[0]) is connected to a speed setpoint (e.g. p1070[0]). The actual percent-
age input value is cyclically converted into the absolute speed setpoint using the reference speed (p2000).
Example 2:
The setpoint from PROFIBUS (r2050[1]) is connected to a speed setpoint (e.g. p1070[0]). The current input value is
cyclically converted into a percentage value via the pre-specified normalization 4000H. This percentage value is
converted to the absolute speed setpoint via reference speed (p2000).
p2001 Reference voltage / Reference voltage
VECTOR Can be changed: T
Data type: Floating Point
P-Group: Communication
Min
10 [Veff]
Description: Sets the reference quantity for voltages.
All voltages specified as relative value are referred to this reference quantity.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
For infeed units, the parameterized device supply voltage (p0210) is pre-assigned as the reference quantity.
Example:
The actual value of the DC link voltage (r0079[0]) is connected to a test socket (e.g. p0771[0]). The actual voltage
value is cyclically converted into a percentage of the reference voltage (p2001) and output according to the param-
eterized scaling.
p2002 Reference current / Reference current
VECTOR Can be changed: T
Data type: Floating Point
P-Group: Communication
Min
0.10 [Aeff]
Description: Sets the reference quantity for currents.
All currents specified as relative value are referred to this reference quantity.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
