Did You Know? Regen Clamp for DC Drives

by Jason Jones

Many servo and stepper systems require a clamping circuit to limit increases in power supply voltage when the motor is decelerating under load. As the motor reduces its speed it increases the voltage on the DC bus of the drive. This is commonly referred to as “regeneration”, and occurs when DC motors are driven by their load. Generally, this situation occurs in cases where a large inertial mass is being decelerated.

Take a quick walk with us down memory lane...

Some 32 years ago a young salesman from an old industrial company saw potential demand for high tech uses of step motors. When he approached his employer about this emerging market, they did not share his enthusiasm or vision.

Applied Motion has embedded help files that are tied to the physical attributes shown in our pictorial representation of the drive within the STAC Configurator™ and ST Configurator™ software applications.

Simply open the STAC Configurator™ or ST Configurator™ software and position your mouse, for example, over the I/O connector of the drive shown. Left click the I/O connector with your mouse, and a new window will open with wiring information for the selected I/O connector.

Digital Signal Processing (DSP) provides the foundation for much of the latest stepper control innovation. Precision current control via custom algorithms within the DSP and encoder feedback allow today’s stepper drive technology to detect stalling of a step motor. Applied Motion Products takes this technology a step further by providing the logic necessary to allow user control of the system current in a near-stall situation to ride through or prevent most stall conditions.

Applied Motion drives offer a variety of control modes, each with its own niche application. Most are intuitive and easily applied: pulse & direction, velocity, streaming commands (SCL). But sometimes these simple approaches don’t quite offer the elusive “perfect” solution. Analog positioning is one such application.

Applied Motion drives with Q programming functionality allow the user to program many different types of moves, interface with various I/O, and perform complicated tasks previously reserved for standalone motion controllers or PLC’s. The Q language is actually pretty easy to use, but the first project in any new language can be intimidating. To help accelerate the learning curve, Applied Motion Products has included a number of sample programs with every Q Programmer installation.

Many Applied Motion drives use screw terminal connectors for easy wiring. But screw terminal connectors take up a lot of space, so most of our programmable drives use higher density “D-SUB” connectors, allowing for more compact designs. Drives with D-SUB connectors include the popular ST, SV, STAC and BLU models.

D-SUB connectors are preferred by many OEMs because cable harnesses can be produced on automated equipment using the “crimp and poke” style mating connectors. Or you can hand solder wires to a “solder cup” style mating connector.

Quick Tuner™ has a built-in scope that is very useful for verifying tuning parameters. For many customers our pre-configured tuning files are all that’s needed to set the servo parameters. You can verify the system’s performance after downloading a pre-configured file by selecting the Sample Move option in the Tuning-Sampling tab. Here you can use a built-in move profile generator to actuate the motor and observe the system performance in the scope screen.
