Avoid overloading
Limit the rated and peak torque of the motor if the transmission ra-
tio is too high.
If you do not limit them, excessively high transmission ratios can
lead in case of error with motor/gear unit combinations to overload
and damage to the gear unit.
Example:
The example shows you how to limit the rated and peak torque of
the motor in the servo drive:
Description
Rated motor torque
Peak motor torque
• 1/5
Description
Rated gear unit torque
Maximum gear unit torque
• 15/24
Gear ratio i = 10
The rated motor torque is not limited. The peak motor torque is lim-
ited to 2.4 Nm.
Observe the operating instructions for the motors
For commissioning, read the original operating instructions for the
motor you are using and carry out the steps in accordance with the
commissioning instructions.
