How Smart Drive Predictive Maintenance
Motor performance with the performance of mechanical movements are directly related
. Except Other Side, the intelligent drive and monitor their own Servo Motor And the mechanical axis of the momentum after. Drive motor control gear and track movement on the response, if more than the tolerance limit of the current axis, smart drive may be the following:
generate alarm message, sent to the controller or the operator;
adjust the drive current to compensate for the mechanical structure of the deviation;
before the situation becomes more serious, stop the implementation of security, protection machinery itself and the product from damage.
Standard smart drive begins in the use of embedded measurement devices, which drive the calibration is quite common, followed by a diagnostic software that is added in.. For those who choose the smart drive users, the good news is that they usually do not need to pay extra to be able to achieve predictive maintenance. The latest drives generally have a built-in diagnostic functions, alarm settings and automatic response by the driver software to complete.
RockwellAutomation company Low Driver Manager StanHo said: "In the past the drive model, the predictive maintenance monitoring of load current by the end user to achieve. If the current increases more than the normal equipment in operation, end users that need to maintain the mechanical systems. Users inform the maintenance team can then investigate. However, RockwellAutomation's latest Allen-BradleyPowerFlex755 drives with standard functions is to monitor and track those affected drive cooling fan and Relay Output information. In addition, users can also program the drive to control machinery or motor bearing hours of work. Software features are standard, no additional software support. "
Designed SinamicsS servo and vector drives SiemensEnergy & Automation Inc. Motion Control Group Product Marketing Manager CraigNelson said, SinamicsS120 drive capacity with a built-in logic programming, and what action to determine in the end. Such a drive "speed feedback device to diagnose the fault, and then switch to non- Sensor To maintain normal operating mode, and also issued alerts. Specific fault will be dealt with at the appropriate time. "SinamicsS120 intelligent diagnosis of another example of the drive circuit and safety related, the user can be programmed to set a response period, if in a cycle, the safety circuit is not working, intelligent drive will alarm.
SinamicsS120 Another feature of the drive is built to track the standard cache. Nelson said: "Even if Power supply Failure, it can still save the day to day measurements. Data can read from the driver software for fault diagnosis and determine the order of events. Drive signals of the tracking data can also be used to diagnose the drive control process, including adjustment and calibration device to adjust tension. "
SEWEurodrive company Electronic Systems Manager RainerNeufeld introduced CONTROLENGINEERINGChina Copyright, the company's smart drives include the Movi-Drive, MoviPro, MoviFit and MoviTrac several brands. Neufeld explained: "They have been called IPOS embedded smart features, which is the company's integrated positioning and sequence control software. Predictive maintenance and will not incur additional costs, users only need to install the IPOS-OT version of the software. "
Neufeld said, by using the Movi PLC Or other controllers, such as RockwellAutomation's Allen-Bradley or Siemens products, drive the monitoring data can interact with other devices or product lines.
