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.
Value in brackets valid for motor with 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.
Provided the power and encoder cables are mounted properly.
