1)
For continuous operation (with 30% n
max
, 60% 2/3 n
max
, 10% standstill) for a cycle duration of 10 min.
2)
Version for increased maximum speed
Maximum continuous speed n
S1
The max. permissible continuous operating speed n
S1
depends on the bearing version and
the shaft height.
CAUTION
If the motor is operated at speeds between n
s1
and n
max
, then a speed duty cycle is
assumed that has time components with low speed and standstill in order that the lubricant
being used can re-generate.
