3. Checking the setting range and minimum speed
Setting range 5m/min: 22m/min ≈ 1:4.4.
This means the standard setting range of 1:50 is sufficient. The option /AZ1Z
(multi- multi-turn encoder with MOVILINK
®
DDI connection) need not be selected.

:
Requirement: In order to avoid thermal problems, the effective torque of the appli-
cation must be smaller than the continuous output torque of the MOVIGEAR
