PFEA112-20 3BSE050091R20 Field Power Drive Modules

The chain protection of PFEA112-20 3BSE050091R20 has the advantage of being timely and reliable. Therefore, when designing the PAT module, the limit alarm signal is used to participate in the chain protection of the output drive: the upper limit alarm input participates in the hardware chain of incremental output, and the lower limit alarm input participates in the chain protection of decremental output. At the moment when the valve reaches the upper limit or lower limit, the PAT module can be directly truncated through the hardware to increase the output or decrease the output, without CPU processing, so as to achieve timely and reliable.

PFEA112-20 3BSE050091R20 module needs to drive the on-site electric actuator through the relay, so the good or bad of the relay is directly related to whether it can be controlled normally. Compared with the commonly used electromagnetic relay, solid state relay is a kind of non-contact switching control relay assembled with solid components, and its input is isolated by photocoupler, so that it can be controlled by a very small current. Since there are no moving parts inside the output part, it has the characteristics of reliable operation, fast switching speed, high operating frequency, long life and no electromagnetic interference. Therefore, it is recommended to use solid-state relays for high-frequency operation.

PFEA112-20 3BSE050091R20 This control scheme to eliminate the oscillation phenomenon can only be reduced by reducing the sensitivity to increase the dead zone DeadZoon, and here DeadZoon is no longer the actual meaning of the dead zone, which contains inertia components. The control of the field has certain requirements on the sensitivity, so the shortcomings of this scheme is very obvious, it is recommended not to use. Motor rotation process inserted into the pause phase, so that the speed control system to reduce the speed, thereby reducing the inertia of the system, the use of this control mode, can be very good to eliminate the oscillation phenomenon, the control accuracy has been greatly improved, but if the whole process using this stepping drive control mode for regulation, regulation time will also be much longer, which is in the industrial use of the process of many occasions is absolutely not allowed.
