Thermal capacity check
O4/O5:
The thermal limits of application are determined by the input drive
assembly (SIMOGEAR geared motor).
O2:
• As a general rule, the solutions offered in
Chapters 5 and 6
are safe
and reliable in operation up to a motor speed of 1500 rpm and an
ambient temperature of 40 °C.
•
See Catalog MD 50.1
for configuring guide
• An arithmetic analysis is performed for O2 variants.
