Application limitations
Reference temperature
Nominal (rated) temperature range
Operating temperature range

4)
At nominal conditions.
5)
The pulse tolerance improves with reduced distance and vice versa.
6)
The data refers only to a central axial alignment. Deviations lead to a change in pulse tolerance.
7)
Note the termination resistances as per RS422.
8)
Heat conductance via the stator base plate necessary over 70C. The temperature of the base plate must
not exceed 85C.
