Scaling parameter
100% = p2000
100% = p2001
100% = p2002
100% = p2003
100% = r2004
100 % = r2000 / 60
100% = Maximum output voltage
without overload
100% = Rated motor flux
100% = 100° C
Example: Setting analog output 0

p2000 = Maximum speed (p1082)
p2001 = 1000 V
p2002 = Current limit (p0640)
p2003 = 2 x rated motor torque
r2004 = (p2003 x p2000 x pi) / 30
