2.2 List of parameters
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.
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: Pre-assigned 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.
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 quantities
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)
p2003 Reference torque / M_ref
