個人的保護導體和接地連接模塊化裝置應從中心接地點徑向布線電源模塊,如連接圖所示。接地電源模塊的連接應連接到電源接地。保護機械所需的措施必須:考慮到這一點。
如有可能,應避免接地電路,因為互連可能導致操作問題。
除了第5.3章和5.4操作驅動器時應注意以下事項:
如果結合電子設備和結構元件,節流閥、接觸器和繼電器等感應負載通過觸點或半導體的方式,則必須適當抑制。直流驅動通過該裝置實現這一點在續流二極管中,交流驅動實現了這一點與接觸器類型相關的布置,
商用RC噪聲直接位于電感的抑制器。
僅噪聲抑制器直接布置在電感處服務于此目的。否則,噪聲級會變得過大并且可能干擾電子設備以及驅動器的操作。所有其他干擾源,如高頻設備(除其他外,乙氧基化設備的部件)應位于控制柜外部并接線。
如果在電子控制驅動器附近使用無線電,則設施正在運行,則必須保持以下條件以排除來自內部的任何干擾:在正常運行期間,控制柜應始終保持關閉狀態,以確保內部有足夠的高頻屏蔽控制柜和電子設備的接線。電機反饋電纜的布線應盡可能靠近:接地金屬表面或接地金屬電纜軸。在調試過程或測試結束時使用無線電驅動器運行時,應避免打開控制柜操作的。如果無線電在傳輸過程中保持在接近打開控制的位置柜門和正朝控制柜內部接線,然后控制電機運動一旦驅動器被釋放,可能會發生,并且沒有更高的排名監視器已激活。
The protective conductors and earthing connections of the individual
modular units should be routed radially from the central earthing point of
the supply module, as outlined in the connection plan. The earthing
connection of the supply module should be connected to the mains
grounding. The measures needed to protect the machinery must be
taken into consideration.
Earth circuits should be avoided, if possible, as interconnections can
cause operating problems.
In addition to the guidelines on line routing, outlined in Chapter 5.3 and
5.4, the following should be noted when operating the drives:
If, in connection with electronic equipment and construction elements,
such inductive loads as throttles, contactors and relays are switched by
means of contacts or semi-conductors, then these must be suitably
suppressed. Direct current actuation achieves this with the arrangement
of the free-wheeling diodes, alternating current actuation achieves this
with the arrangement of contactor type-related, commercial RC noise
suppressors located directly at the inductance.
Only the noise suppressor arranged directly at the inductance
serves this purpose. Otherwise the noise level becomes too excessive
and can interfere in the electronics as well as the operation of the drive.
All other sources of interference, such as high-frequency equipment
(components of eloxadizing equipment, amongst others) should be
located and wired outside of the control cabinet.
If radios are used near the electronically controlled drive while the facility
is running, then the following conditions must be maintained to exclude
any interference from within:
The control cabinets should always remain closed during normal operation to guarantee a sufficient high-frequency shielding of the internal
wiring of the control cabinet and of the electronic equipment.
The motor feedback cable should be routed as close as possible to
grounded metal surfaces or in grounded metal cable shafts.Working with radios during the commissioning process or testing close
to an open control cabinet should be avoided while the drives are being
operated. If radios are held during transmission close to the open control
cabinet door and are pointing at an unfavorable angle in the direction of
the control cabinet internal wiring, then uncontrolled motor movements
are likely to occur once the drive is released and no higher-ranking
monitor has been activated.
