Reference Torque / M_Ref; Reference Power / P_Ref - Siemens SINAMICS G120XA Operating Instructions Manual

NOTICE
If various DDS are used with different motor data, then the reference quantities remain the same as these are not
changed over with the DDS. The resulting conversion factor must be taken into account.
Example:
p2002 = 100 A
Reference quantity 100 A corresponds to 100 %
p0305[0] = 100 A
Rated motor current 100 A for MDS0 in DDS0 --> 100 % corresponds to 100 % of the rated motor current
p0305[1] = 50 A
Rated motor current 50 A for MDS1 in DDS1 --> 100 % corresponds to 200 % of the rated motor current
When the reference current is changed, short-term communication interruptions may occur.
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
Can be changed: T
Unit 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.

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.
