Reference Torque / M_Ref; Reference Power / P_Ref - Siemens SINAMICS G150 Manual

p0305[1] = 50 A
Rated motor current 50 A for MDS1 in DDS1 --> 100 % corresponds to 200 % of the rated motor current
Note: For the automatic calculation (p0340 = 1, p3900 > 0) an appropriate pre-assignment is only made if the parameter is
not inhibited from being overwritten using p0573 = 1.
SERVO:
Preassigned value for p0338 > 0.001 is p0338, otherwise 2 * p0305.
VECTOR:
Preassigned 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.

Reference torque / M_ref

VECTOR_G Can be changed: T
Data type: FloatingPoint32
P-Group: Communications
Not for motor type: -
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).
Note: For the automatic calculation (p0340 = 1, p3900 > 0) an appropriate pre-assignment is only made if the parameter is
not inhibited from being overwritten using p0573 = 1.
SERVO:
Preassigned value for p0338 and p0334 > 0.001 is p0338 * p0334, otherwise 2 * p0333.
VECTOR:
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.

Reference power / P_ref

B_INF, VECTOR_G Can be changed: -
Data type: FloatingPoint32
P-Group: Communications
Not for motor type: -
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.
