Mount the servo motor on a flange which has the following size or produces an equivalent or higher heat
dissipation effect:
4-1-7 Overload protection characteristics
The servo drive unit has an electronic thermal relay to protect the servomotor and servo drive unit from
overloads. The operation characteristics of the electronic thermal relay are shown below when standard
parameters (SV021=60, SV022=150) are set. If overload operation over the electronic thermal relay
protection curve shown below is carried out, overload 1 (alarm 50) will occur. If the maximum torque is
commanded continuously for one second or more due to a machine collision, etc., overload 2 (alarm 51) will
occur.
