(3) When installing the servomotor horizontally, set the power cable and detector cable to face downward. 
When installing vertically or on an inclination, provide a cable trap.
4-1-6 Installation of servo motor
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.
1. The servomotors, including those having IP67 specifications, do not have a completely waterproof 
(oil-proof) structure. Do not allow oil or water to constantly contact the motor, enter the motor, or 
accumulate on the motor. Oil can also enter the motor through cutting chip accumulation, so be 
careful of this also.
2. When the motor is installed facing upwards, take measures on the machine side so that gear oil, 
etc., does not flow onto the motor shaft.
