Figure 6-1 Illustration of conversion with reference values

Note

If a referenced form is selected and the reference parameters (e.g. p2000) are changed retrospectively, the referenced values of some of the control parameters are also adjusted to ensure that the control behavior is unaffected.

Using STARTER offline

Following offline drive configuration, the reference parameters are preset; they can be changed and protected under Drive -> Configuration -> "Disabled list" tab.

Note

If the reference values (p2000 to p2007) are changed offline in STARTER, it can lead to boundary violations of the parameter values, which cause error messages during loading to the drive.

Scaling parameter

Default at initial commissioning

Reference speed

100 % = p2000

p2000 = Maximum speed (p1082)

Reference voltage

100 % = p2001

p2001 = 1000 V

Reference current

100 % = p2002

p2002 = Current limit (p0640)

Reference torque

100 % = p2003

p2003 = 2 * rated motor torque (p0333)

Reference power

100 % = r2004

r2004 = p2003 * p2000 * 2π / 60

Reference angle

100% = p2005

90°

Reference acceleration

100% = p2007

0.01 1/s2

Reference frequency

100 % = p2000/60

Reference modulation depth

100 % = Maximum output voltage

Reference flux

100 % = Rated motor flux

-

Reference temperature

100% = 100°C

-

Reference electrical angle

100 % = 90°
