Dimensions Of Servo Motor - HNC Electric SV-E3 Series Instruction Manual

●Install the drives in the vertical direction. Please use two M5 screws to fix the drive, master drive and slave drive
respectively which is less than 800W Please use three M5 screws to fix the drive and master drive respectively which is
more than 1kW.
●In order to ensure that surrounding temperature between internal boards is not more than 55℃, cooling fan or cooler need
to be installed to reduce the temperature, when the drives are installed in the sealed cabinet.
●The temperature on the surface of cooling plate would be 30℃ higher than the surrounding temperature.
●Use heat-resistant material for the wiring and isolate wiring from the machine and other cables which are easily affected by
the temperature.
●The service life of servo drive depends on the temperature around the electrolytic capacitor. When the electrolytic capacitor
is close to the service life, the static capacity will decrease and internal resistance will increase. Consequently, it will lead to
overvoltage alarm, malfunction caused by noise and components damage. The service life of electrolytic capacitor is approx. 5
to 6 years under the condition「average annual temperature 30℃, load rate 80% and operation of less than 20 hours a day on
average」
Additional instructions
①The motor shaft is covered with anti-rust oil before leaving factory. Please have the antirust treatment again to the shaft to
prevent it from rust when installing load.
②Never disassemble the encoder or motor.
③The GND of 24VDC input and the grounding cable of device can be connected to each other.
※Please use the same power supply for control voltage(24V and GND) and upper control device.
④Do not remove or maintain the encoder battery until the main power supply is switched OFF.
⑤After switching off the main power supply, please note that there is residual voltage of approx. 30 seconds on the power
components.
⑥Do not replace the fuse.
⑦The servo drives of more than 750W are installed with a cooling fan on the right side. Do not touch or block the ventilation
ports of servo drive
