Who USES the step motor closed loop controller
SANYO DENKI is an innovative closed-loop stepping motor controller with high resolution encoder and continuously monitoring the position of the current motor shaft. With the encoder feedback function, the current location information is updated every 25 microseconds. If there is a will, the SANYO DENKI servo immediately takes corrective action to make up for the lost pace. For example, because of the sudden change in load, in the missing step state, this is a typical step forward motor defect. 4, In order to improve the overall control performance, the gain of the servo system is the most critical step. Adjusting parameters according to load changes is a long, tedious, cumbersome, time-consuming effort to apply a field engineer. SANYO DENKI stepping servo completely unique algorithm adopts stepper motor control, closed loop, eliminate these cumbersome steps, and to give engineers a high-performance servo system. SANYO DENKI stepping servo is very suitable for low load stiffness (for example, the belt and pulley system), the most common problems in the servo system is, in the case of different rigid load servo system cannot maintain the best performance. SANYO DENKI is able to maintain the best servo effect across the entire range without the need for tedious adjustments.
The "location table" is used for the movement control program of the main controller's digital input and output signals. You can operate the motor directly by sending a digital table, starting/stopping, the origin looking for or from other input values of a PLC. PLC can be monitored from the driver's location to complete the signal, the origin search, move/stop, servo and other digital output signals. The driver can be up to 256 locations.
Closed loop step system. SANYO closed-loop step system (we call it the SANYO petabyte series) features: With ac servo motor and stepper motor system advantages, compact structure, high speed and high deceleration can be run, stop when there is no adjustment, excellent performance, the most suitable for the visual system. Suitable for machine vision detection equipment, label making machine, liquid crystal manufacturing equipment, small engraving machine, robot, semiconductor processing device (binding, braid, sorting machine...). And so on. 1, SANYO DENKI can also be controlled by the rs-485 communication (compatible with other brand controllers), as well as input commands controlled by the driver. Pulse connections can control multiple axes. All the motion parameters can be stored in Flash ROM via network Settings. Provides a programming library (DLL) under Windows 2000 / XP.
Closed loop stepper is not a simple superposition of encoder and the mechanical combination of open loop step, but after the thunder game developers rigorous theoretical arithmetic and a large number of long-term practical experience of chemical reaction to create a stunner high-performance low-cost labor. The industry, including any other closed loop in the world, is modeled after the lightning match. Because the idea of a closed-loop step (which is called hybrid servo) was developed and developed by resai. The reason why the resai is called hybrid servo is what other manufacturers call a closed-loop step with deep meaning. Personally think: because ray to apply this technology to the limit, product performance has perfect step by step and comprehensive performance of the servo, so called hybrid servo, this also is a kind of confidence and pride. Other companies that follow suit are called closed-loop, which is not what they call hybrid servos because their product is far from the server. They did not absorb the technology of the thunder race, which was a semi-finished product.
The closed-loop driving system of EZS57 + 57hs30en-1000 is applied in the screw machine, with high efficiency, no losing step, no vibration, low fever and so on. The closed-loop drive system is not much different from the ac servo in the medium and low speed application, but the cost is much lower.
