When the power failure of the 611d server is driven, the main axle is set at 3000 r/min, and the equipment is activated, and the system is in normal operation, but when the system turns at > 3000 r/min, the 611d power unit is in error, an electrical alarm is performed and the system is stopped. After multiple inspections of the system, no mechanical anomalies were detected, circuit boards and components were in normal condition, after replacement of the 611d power unit, and after replacement of the malfunctioning power unit, the system returned to normal operation. The use of the siemens digital maintenance system is widespread, requiring the transport staff to master their maintenance, failure diagnosis and failure maintenance methods. Transport personnel can perform failure diagnosis through sensor analysis, parameter correction and logical methods and take appropriate maintenance measures to ensure the stable operation of the system, depending on the specific condition of the failure.

The digital control system currently configured for the digital machine is mainly a japanese fanuc and german siemens system, and how to improve the dynamic properties of the server-driven system is also an important task for maintenance and commissioning personnel. The purpose of the server drive optimization is to match the electromechanical system better for better stability and dynamic performance. In numerically controlled machine beds, the mismatch of electromechanical systems usually causes problems such as bed vibrations, excessive surface cutting of processed parts and poor surface quality. In particular, in grinding equipment processing, optimization of the service drive is necessary. The dms server drive consists of three feedback loops, i. E. Position loop, speed loop and current loop. The rate of reaction of the inner loop is high and the rate of intermediate reaction must be higher than that of the outer ring, and failure to comply with this principle will cause vibration or poor reaction.

Siemens digital control maintenance, which is located at the site of a failure-prone location throughout the plc control system, is prone to malfunction in the following areas. In the day-to-day maintenance of relays, contacts, such as the plc control system of a production line, electrical spare parts consume larger quantities of relays or air switches. In addition to the quality of the product itself, it is mainly due to the harsher conditions in the field. For example, contact points exposed to the production environment are prone to fire or oxidation, and gradually heat-distorting until they are not usable. All control boxes at the site of the production line were selected for better closed cabinets, and their inner metaware had a significantly longer useful life than others using open cabinet inner metaware. Therefore, avoiding such malfunctions should maximize the use of high-performance relays and improve the environment for the use of metaphones, thereby reducing the frequency of replacement and the impact on system operations。
The 840d system is similar to the 840dsl system and signals are: channel access to maintain: db21. Dbx6. 0; axle signal coordinate axis/main axis prohibited: db3*. Dbx1. 3; multiplier effect: db3*. Dbx1. 7; measurement system effective: db3*. Dbx1. 5; entry to maintain: db3*. Dbx4. 3; terminal 9/663; db3*. Dbx2. 1, db3*. Dbx21. 7. In the case of siemens 808d with a v60 drive, if the direction key is pressed, there is a hint of “lack of axle energy” and sinamis v60 shows a “s-3” or “s-4” alarm, the following aspects can be examined: a call to shanghai to consult with siemens for numerical maintenance.

The checking of power modules in siemens 840d had a relatively high percentage of power module failures, and transport personnel were required to perform periodic checks of power modules to ensure their steady operation. In general, the power module is inspected mainly using the manng table, which accurately measures the system's current and voltage values, and allows the system's failure to be detected by comparing the measurements with the standard parameters. In the normal operation of the siemens 840d digital control system, the electrical resistance measured in the manng table is infinite. Optimizing drivers: for siemens 840d digital control systems, optimising drivers is optimizing current rings, position rings and speed rings. The optimisation of the electron ring is relatively simple, as the manufacturer has set the parameters according to the better principles when the current is out of the plant. The optimisation of the circulation ring by the transporter is the inspection and operational testing of the current circulation parameters; the optimisation of the position ring requires the adaptation of the optimisation measures by the transporter according to the actual state of operation; the pacing measures need to be carried out in terms of speed and materials, which can be optimized by the transporter through better speed setting; the best speed of the siemens 840d control system is 10 m/s, and the material of the speed ring needs to meet standard requirements and be well driven to ensure the stable operation of the speed ring.

Siemens numerically controlled failure points may occur on switches, limit positions, security protection and some components or equipment operating on the ground as a result of prolonged wear or tearing or decay. If the fabric vehicle on the tailings pool of the production line is frequently moving back and forth and the dust is larger on the ground, deformation, oxidation, dust plugging, etc. At the point of contact close to the switch leads to poor contact at the point or to a lack of institutional sensitivity. The treatment of such equipment malfunctions is mainly reflected in the regular maintenance, which keeps the equipment in a state of constant integrity. For limit switches, especially on heavy equipment, multiple protective measures are added to the design process, in addition to periodic overhauls.
