Note: Preassigned value is p0640.
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 rated line current, which is obtained from the rated power and parameterized rated line supply
voltage (p2002 = r0206 / p0210 / 1.73) is pre-assigned as the reference quantity.
Example:
The actual value of a phase current (r0069[0]) is connected to a test socket (e.g. p0771[0]). The actual current
value is cyclically converted into a percentage of the reference current (p2002) and output according to the param-
eterized scaling.
p2003 Reference torque / M_ref
Access level: 3
Can be changed: T
Units group: 7_2
Min
0.01 [Nm]
Description: Sets the reference quantity for torque.
All torques specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
Dependency: This parameter is only updated during the automatic calculation (p0340 = 1, p3900 > 0) if motor commissioning was
carried out beforehand for drive data set zero. This means that the parameter is not locked against overwriting
using p0573 = 1.
Refer to: r3996
Notice: When the reference torque is changed, short-term communication interruptions may occur.
Note: Preassigned value is 2 * p0333.
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 / P_ref
Access level: 3
Can be changed: -
Units group: 14_10
Min
- [kW]
Description: Displays the reference quantity for power.
All power ratings specified as relative value are referred to this reference quantity.
The reference quantity corresponds to 100% or 4000 hex (word) or 4000 0000 hex (double word).
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)
