K
m
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.
Without holding brake.
Applicable to Bosch 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.
