Digital Vs Analogue Servo Drives
The last decade has seen a tremendous in servo drive functions with respect to size, rotational speed and the torque produced. Digital servo drives are one more step towards the further improvement in their functionalities.
In this article we will try to analyze the operational and fundamental aspects that drive the digital and the analogue servo drives and try to reach a conclusion as to which has higher efficiency.
Digital servos have noteworthy operational benefits over analogue servos. The fact remains the same even in case of the coreless versions. As in all general motor functioning aspects, with these advantages of digital servo drives also comes some minor disadvantages. Where a digital servo differs from an analogue servo drive is in the means it processes incoming information and produces output that in turn manages the initial power needed to drive the servomotor. This helps in reducing dead band thereby enhancing resolution and produce remarkable holding power.
Now let us consider the advantages that an analogue servo drive has. Technically, analogue servo drives have lower cost with respect to very high efficiency. This has been confirmed with a tachometer reader. The extensive bandwidth present in the brush tachometer facilitates high gains that can be used without producing stability problems like jitter at standstill that is a very common problem produced in servo drives in a stiff system. On the other side the digital servo drive is more costly but comparatively easy to install and corrections can be incorporated fast across several units. One disadvantage that can have a negative effect on its overall performance is automatic self-tuning in cases where the load parameters are difficult to measure. The digital servo drive also put forwards the opportunity of active tuning. This has proved to be vital in cases where the load inertia can change dramatically during machine functioning. Such a condition is clearly out of question when a potentiometer-adjusted drive is functioning.
Most analogue drives get configured either as torque or velocity amplifiers via a switch or even with jumper links. In practicality, while the input signal has to be still taken to the same point, the velocity amplifier gets bypassed. In digital servo drives working for a servo motor, a small chip or microprocessor is used to carry out all the basic motion control functions. This also helps to drive a D-to-A converter to generate an analogue torque. From this point onwards, the drive functions like an analogue servo drive. This is the reason why a digital servo is capable of producing signals at high frequencies.
