Note
Pre-assigned value is p0640.
If a BICO interconnection is established between different physical quantities, then the particular reference quantities
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 parameterized
scaling.
p2003 Reference torque / M_ref
Access level: 3 Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T Scaling: - Dynamic index: -
Unit group: 7_2 Unit selection: p0505 Function diagram: -
Min:
0.01 [Nm]
Max:
20000000.00 [Nm]
Factory setting:
1.00 [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.

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 quantities
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 cyclically
converted into a percentage of the reference torque (p2003) and output according to the parameterized scaling.
r2004 Reference power / P_ref
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: - Dynamic index: -
Unit group: 14_10 Unit selection: p0505 Function diagram: -
Min:
- [kW]
Max:
- [kW]
Factory setting:
- [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.
