Continuous speed n
S1
The max. permissible continuous operating speed n
S1
depends on the bearings
and the shaft height (refer to Table 1-14).

Important
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.
1) Mechanical limiting speed (permissible for 10 min. cycle with: 3 min n
max
, 6 min 2/3 n
max
, 1 min stand-
still)
2) Max. continuous operating speed
3) Only coupling out-drive is permissible
