INSTALLTION of Protection from oil and water
(1) Next, the servo motor is not waterproof (IP44). Do not subject the servo motor to oil and water.
Especially for the HC-MF / HC-KF / HC-AQ / HC-KFS / HC-MFS and HA-FF series, do not subject the
shaft-through portion to oil.
(2) When the gear box is mounted horizontally, the oil level in the gear box should always be lower than
the oil seal lip on the servo motor shaft. If it is higher than the oil seal lip, oil will enter the servo motor, leading to a fault. The HC-MF / HC-KF / HC-AQ / HC-MFS and HC-KFS series servo motor is not equipped with an oil seal and cannot be used with the gear box as described above. Oil should be shut off on the gear box side.
(3) When installing the servo motor horizontally, face the power cable and encoder cable downward. When installing the servo motor vertically or obliquely, provide a trap for the cable.
(4) Do not use the servo motor with its cable soaked in oil or water. (Figure on the right)
(5) When the servo motor is to be installed with the shaft end at top, provide measures so that it is not
exposed to oil and water entering from the machine side, gear box, etc.
(6) If the servo motor is exposed to oil such as coolant, the sealant, packing, cable and others may be
affected depending on the oil type.
(7) In the environment where the servo motor is exposed to oil mist, oil, water, grease and/or like, the
servo motor of the standard specifications may not be usable. Contact us.
(8) In the case of the servo motor with oil seal, the oil seal may sound during operation. It poses no
problems in function.
