is to be used for calculations with crest values (I
dN
, I
max
). For calculations with root-mean-square values (rated data), the torque
constant K
m
must be multiplied by a factor of
2
.
Values determined according to EN 60034-1. Current and voltage specified as root-mean-square values.
Use the declared value in bracket for motors holding brake.
Applicable to REXROTH cables. Rated according to VDE0298-4 (1992) and installation type B2 according to EN 60204-1 (1993) at
an ambient temperature of 40 °C.
Without blower unit.
If the limits specified are exceeded, the performance data must be reduced if necessary. For reduction factors, refer to the chapter
entitled “Environmental Conditions”.
Provided the power and encoder cables are mounted properly
