Mount the servo motor on a flange which has the following size or produces an equivalent or higher heat 

dissipation effect:

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.
