Parameter
List of parameters
Example 1:
The signal of an analog input (e.g. r4055[0]) is connected to a speed setpoint (e.g. p1070[0]). The actual percent-
age input value is cyclically converted into the absolute speed setpoint using the reference speed (p2000).
Example 2:
The setpoint from PROFIBUS (r2050[1]) is connected to a speed setpoint (e.g. p1070[0]). The actual input value is
cyclically converted into a percentage value via the pre-specified scaling 4000 hex. This percentage value is con-
verted to the absolute speed setpoint via reference speed (p2000).

Description: Sets the reference quantity for voltages.
All voltages specified as relative value are referred to this reference quantity. This also applies for direct voltage val-
ues (= rms value) like the DC-link voltage.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
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.
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 parameterized device supply voltage (p0210) is pre-assigned as the reference quantity.
Example:
The actual value of the DC link voltage (r0070) is connected to a test socket (e.g. p0771[0]). The actual voltage
value is cyclically converted into a percentage of the reference voltage (p2001) and output according to the param-
eterized scaling.
p2002 Reference current / I_ref
SERVO_S110-CAN, Can be changed: T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN

Not for motor type: -

0.10 [Arms]
Description: Sets the reference quantity for currents.
All currents specified as relative value are referred to this reference quantity.
The reference quantity in this parameter corresponds to 100% or 4000 hex or 4000 0000 hex.
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 should be taken into account (e.g. for trace records).
Example:
p2002 = 100 A
Reference quantity 100 A corresponds to 100 %
p305[0] = 100 A
Rated motor current 100 A for MDS0 in DDS0 --> 100 % corresponds to 100 % of the rated motor current
p305[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.
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.
