Torque load
To prevent thermal overloading of the motors, the effective
load torque must not be greater than the nominal torque of the
servomotor.
Maximum pulse torque
Typically 2 to 5 times nominal torque, depending on controller
assignment.
3 to 5 times nominal torque is permissible for max. 0.2 s.
Bearing service life
The average service life under nominal conditions
(Mmax.
≤
MN) is 20,000 h.
