The alternative in motion control
The Mitsubishi serial encoder transmits the information of its angular position in a purely serial way, therefore unlike other models (for example EnDAT) there are no sinusoidal signals. The number of wires used is reduced: 4 wires for serial data and 2 wires for power. Serial data is transmitted and received by two pairs of...
In this article I present the family of digital servo drives for d.c. motors with SCR bridge called “D SERIES“. Why is it called with this name? Our loyal customers will surely have used our 12IRC, 12SPC, 6AXC and 6IC drives at least once: they were born in the ’80s and were grouped in the...Continue reading
How can we drive an electric motor equipped with a Fanuc Pulsecoder? Let’s go back in time For decades the d.c. tacho-generator was used as a speed transducer for electric motors; all the control equipment had an input for this type of transducer and there were no compatibility problems. Then the resolvers and TTL encoders...Continue reading
Having the right accessories to complete your servo drive is essential for its correct operation and to comply with regulations such as the Electromagnetic Compatibility standards. In this post we will talk about: Inductors (three-phase chokes, smoothing inductors) Resistors for motor braking energy dissipation Power-supply units capable to recover motor braking energy to mains EMC...Continue reading
After having examined, in the previous post, how to figure out what servomotor we are using, what kind of data we need and where to find them, we are now looking at how to use that information to choose the right servo drive. The essential parameters needed to choose a new servo drive are: Type...Continue reading
When a customer asks us what drive he should choose to replace a damaged one, the first question we ask is always the same: what kind of motor does the converter control? The motor data needed are: Type (e.g. DC, brushless, induction) Electrical specifications (e.g. armature current, supply voltage) Type of speed transducer mounted (e.g....Continue reading
