Failure to follow these precautions can result in serious or possibly even fatal injury and damage to products or related equipment or system. This symbol indicates the presence of a potentially hazardous condition which, if not avoided, could result in serious personal injury or death. This precautionary symbol appears in labels attached to YASNAC products to alert the user to conditions requiring concern for safety.

Therefore, it may be necessary to make connection changes in accordance with the needs of standard cabinets and integrated equipment. The following symbols are used in this connection manual to emphasize particular information to the user:. Indicates important information to be remembered, i. An example of this warning method is as follows:.
Failure to observe these precautions may result in personal injury or product damage. Ambient temperature: o C to 65 o C -5 o F to o F. Remove the substance using a clean cloth.
When connecting the motor shaft to a driven machine, be sure to center-align accurately to prevent vibration. Mount the servo unit Converter,Inverter and Amplifier vertcally and fasten firmly in place with screws or bolts.
Since the servo unit Converter,Inverter and Amplifier will generate heat, install the unit with sufficient clearance for cooling air flow. When circulating air inside of the enclosure, do not blow air directly onto the servo unit since dust contamination could occur. This helps prevent malfunction.
The power supply unit, UPS, is available as an option. Ample separation of signal wires from power wires will reduce the noise influence.
Refer to the section in this connection manual for noise filter specifications and capacities. Use of the correct noise filter will reduce noise influence.
Damage to the device will occur if incorrectly connected. When the ambient temperature exceeds 30 o C 86 o F , the allowable current drops. When the current capacity is low, install an additional external power unit. Limit the average temperature rise of air within the enclosure to less than 10 o C 50 o F compared to the ambient temperature.
Use a UL approved fan to circuate the air in a closed enclosure to improve cooling efficiency, and to prevent abnormal heat rise. Seal the cable inlet, door, etc. Since a CRT display attracts airborne particles due to its high voltage that could result in malfunction, therefore, provide an enclosure capable of preventing dust from entering the CPU. Ambient magnetic field may cause CRT screen fluctuations, therefore, prevent this with a layout and magentism shield.
In PC NC Unit,printed circuit boards,various units may accumlate dust from air,may result in malfunction,therfore ,make structures to prevent the entry of dust. Install packing on the cable inlet,doors,back covers,etc. See the following example:. Even though the unit has been turned OFF, it is still in charged status, so do not touch any component parts for a minimum of five minutes. Failure to observe this precaution could result in personal injury.
Never modify the product. Never change the set values of the components and any variable resistors used in control panel. This section addresses the basic system: configuration, specifications, enclosure design, electrical connections and installation. Note: Avoid installing the control panel in a location subject to direct sunlight, near heat generating devices or outdoors even if the ambient temperature is within the specified range. Design of the enclosure should be made on the basis that the average temperature increase of air within the enclosure containing the PC NC unit and other components should be 10 o C below the external air temperature.
Efficient heat diffusion area is independently located, so bottom area is excluded. Where cooling capacity is insufficient even with a circulating fan mounted in the enclosure, Yaskawa can provide heat exchangers.
The heat generation indicated in the above table is the allowable heat generated when the internal temperature increase in the enclosure is limited to under 10 o C. The amount of internal heat generated to make the internal temperature under 10 o C when the enclosure is equipped with a HEATEX02 Heat Exchanger is expressed by the following equation:.
Heat exchanger should be mounted on the enclosure provided by the machine tool builder. Mount the exchanger so that the internal air is drawn from the upper portion and discharged through the lower portion, while external air is drawn in from the lower portion and discharged through the upper portion. Internal air. External air. Heat exchanger. Fig 1. PCNC units and other components especially CRTs housed in a machine tool enclosure are exposed to an environment with airborne matter, e.
Since these elements could cause control component malfunction, enclosures should be designed and built to prevent such matter from entering as follows:. Refer to Fig. Refer to Fig, 1. The periphery should be sealed with suitable materials. Seal the cable inlet, door, rear lid opening clearances with packing material.
Since oil will enter the enclosure through screw holes and collect on the internal ceiling surface, apply suitable packing material to seal these holes. Metal fitting. To prevent this, keep magnetic generating materials, e.
The value of mm is a general standard and could vary depending on the situation, therefore, be aware of the presence of magnetic generating sources when positioning the CRT unit. If the cables wired to the PCNC unit need to be shielded, they must be grounded using the grounding plate with cable clamp hardware.
Because this clamp serves both as cable support and shielding, they must be installed carefully so that safe system motion can be assured. To set the CNC up for drip feed: drip feed not available on this control These settings have been collected from users of our software and machine tool distributers.
Since we have no control over the many variables involved, including such things as cable conditions, modifications to machines, condition of computer hardware, etc. To open the file correctly, please click the Information Bar on the top of the browser window, and select "Allow Blocked Content".
