 The Hybrid Servo Controller must be installed vertically with screws to sturdy structures. Do not
install it upside down, tilted, or horizontally.
 Since heat is generated when Hybrid Servo Controller is running, good circulation of the
cooling air must be provided as shown in the figure above. Certain space is reserved in the
design to allow the heat generated to dissipate upwards. As a result, do not install the machine
below any equipment that cannot stand excessive heat. If the machine is installed in the control
plate, special care must be given to maintain good air flow for cooling so that the surrounding
temperature of Hybrid Servo Controller won't exceed the regulated values. Do not install Hybrid
Servo Controller in any closed box with poor air flow and cooling, which will lead to machine
malfunction.
 As the Hybrid Servo Controller is running, the temperature of the cooling plate will change with
the ambient temperature and the load, with the maximum temperature reaching to about 90°C.
Therefore, the backside of installation materials for Hybrid Servo Controller must be able to
sustain high temperature.
 When multiple Servo Controllers are installed in one single control plate, it is recommended to
install them with laterally to avoid heat interference among each other. If stacking installation is
needed, spacers must be installed to minimize the effect of the heat from the lower machine on
the upper machine.
NOTE
Do not let any foreign objects such as fiber, paper pieces, wood chips or metal pieces to adhere to the cooling
fan of the hybrid servo motor. The product should be installed in a control plate made of inflammable
materials such as metal to avoid the risk of fire
