Reference speed
100% = p2000
p2000
Reference voltage
100% = p2001
p2001 = 1,000 V
Reference current
100% = p2002
p2002 = Current limit (p0640)
Reference torque
100% = p2003
p2003 = 2 × rated motor torque
Reference power
100% = r2004
r2004 = (p2003 × p2000 × π) / 30
Reference temperature 100% = 100 °C -
