[Note]

※When the motor rotates under 180 degree, single revolution accuracy decreases.

※When use the motor with brake, please follow the brake voltage specified in the manual.

※When the brake voltage is under 12V or use under the reverse polarity, single revolution accuracy decreases.

2.2.5 About oil seal

Please use oil seal to prevent the entry of oil into the servo motor via the output shaft when using motor with gear box. All the

SV-E3 series motors are installed with the oil seal.

●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

communication(the upper controller is wired with one servo drive), the parameters of multiple servo drives can be changed

and the waveform of position deviation and rotation speed can be monitored by the upper controller.

The wiring length between each drives CN1 should be 250mm or less.

Terminal resistance

Connect the terminal resistor between 43pin and 44pin of CN1 to the last drive and to the upper controller.

Figure 4.4.1 Multi-station connection example

The wiring between the drives are shown as above. And daisy-chained connection should be performed between the drive

connector CN1 and the upper controller.

[Communication address setting]

When using multi-station communication, set the different communication address for each drive according to the following

steps. There are two setting methods: by set panel and dedicated software.

Input 24V control power supply after wiring, then operate as the following steps For wiring, refer to section 4.1[Wiring

diagram].

38

[Setting method by set panel]

①Press the MODE button three times from the initial display status. The leftmost display on the LCD (6 digits) is [P] to come to

the parameter setting mode. There is 3 digits, the point(.) and 1 digit on the right side of [P]. And the rightmost display is blank

or [r]. The parameter number is represented by 3 digits, the point(.) and 1 digit.

②Press the UP/DOWN and SHIFT button, when [P004.0r] shows, press SET button to display the current setting value. The

initial value is [1].

③Press the UP/DOWN and SHIFT button and input the expected communication address. Setting range is from 1 to 32.

④Press the SET button to RAM, the indicator changes from flicker to lit.

⑤Press the MODE button three times to display [SAVE_P].

⑥ Press the SET button, the [P] in [SAVE_P] flicker. When the parameter is stored in the EEPROM normally, [nr_End]

displays.

⑦Notes: Cut off the power supply to the servo drive(Note1). Before restart the power supply, the servo drive operates as the

former communication address.

⑧Set the communication address to the other drive as the same way described from ① to ⑦. When the single-axis drive are

used in parallel, please set the communication address by the set panel of the servo drive.
