    Why You Need a Surge Protection Device?

    When a current spike or voltage surge suddenly occurs in an electrical circuit or a communication line due to external interference like lightning, surge protection device (SPD) can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit. It is an indispensable device for lightning protection in the electronic equipment. But some people are still wondering why we need it, or whether need it when we have other lightning protection device? The following FAQ will give your answer for "Why you need a surge protection device".

    What Communication type is used for Servo Motor & Drive System?

    Sometimes one has to (still) use a dedicated net just for servos but that is old. Different fieldbuses and/or servo drive interfaces may support a partial frame; for example, one may only be able to set a control word which might be position or torque command while some may support a full parameter frame or command set which exposes a plethora of servo parameters and variations between the two extremes. Speed is also a consideration i.e. may only be fast enough to do motion control or fast enough to close a servo torque loops and/or fast enough to incorporate feedback devices e.g. force or range sensors (without wiring directly to the servo drive).
