Parameters
List of Parameters
p2003 Reference torque / Reference torque
Access level: 3
Can be changed: T
Min
0.01 [Nm]
Description: Sets the reference quantity for torques.
All torques 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.
Dependency: p2003 is only updated during automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning has been carried
out first for drive data set zero and as a result overwriting of the parameter has not been blocked by setting p0573 =
1.
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
Example:
The actual value of the total torque (r0079]) is connected to a test socket (e.g. p0771[0]). The actual torque is cycli-
cally converted into a percentage of the reference torque (p2003) and output according to the parameterized scal-
ing.
r2004 Reference power / Reference power
Access level: 3
Unit: [kW]
Description: Displays the reference quantity for power ratings.
All power ratings 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.
Dependency: This value is calculated as follows:
Infeed: Calculated from voltage times current.
Closed-loop control: Calculated from torque times speed.
Refer to: p2000, p2001, p2002, p2003
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
The reference power is calculated as follows:
- 2 * Pi * reference speed / 60 * reference torque (motor)
- reference voltage * reference current * root(3) (infeed)
p2005 Reference angle / Reference angle
Access level: 4
Can be changed: T
Min
90.00 [°]
Description: Sets the reference quantity for angle.
All angles 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.
Dependency: p2005 is only updated during automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning has been carried
out first for drive data set zero and as a result overwriting of the parameter has not been blocked by setting p0573 =
1.
Note: If a BICO interconnection is established between different physical quantities, then the particular reference quanti-
ties are used as internal conversion factor.
