Part two of three: Servo-system regenerative resistor types and accessories
In the first installment of this series, we explained the regenerative-power requirements for the controlled motion of servomotor systems. Here we detail common electrical protection circuitry. By Hurley Gill • Senior applications and systems engineer | Kollmorgen Designing a machine with servomotors, drives, and regenerative resistors requires consideration of numerous design factors. These components affect […]
What is external device monitoring and how does it relate to machine safety?
According to the Machinery Directive 2006/42/EC, technical protective measures should be used to reduce risks that cannot be avoided through safe design measures. These technical protective measures include safety devices such as door locks, covers, light curtains, and other equipment that monitors the machine movements. When the safety device controls and external device, such as […]
What machine safety functions address speed, and when are they used?
The Machinery Directive 2006/42/EC states that when a machine manufacturer is unable to eliminate the risks of potential hazardous situations (for example, mechanical hazards such as crushing or cutting) through safe design methods, the next step is to reduce the risks through technical protective measures. These technical measures include protective devices, such as door locks […]
Motion system design: How to manage inertia mismatch
One of the most important parameters when sizing a motion system is the inertia of the load being moved. Regardless of the type of motor being used — AC induction, stepper, brushless DC, or AC servo — the ratio of the load inertia to the motor inertia has an important influence on system performance. If the […]
Common dc bus servo drives for applications with regenerative energy needs
The new MELSERVO-J5D servo amplifiers from Mitsubishi Electric Automation, Inc. offer a unique servo-based solution for applications that need to handle regenerative energy. The common dc bus servo drives are ideal for medium to large servo applications that require multiple drive units capable of managing regenerative energy. Available in 400 V and 1 kW to […]
What is cyclic synchronous control (position, velocity, and torque)?
Cyclic synchronous control modes — cyclic synchronous position, cyclic synchronous velocity, and cyclic synchronous torque — are standardized operation modes of drives, defined in the CiA 402 profile specification, CANopen device profile for drives and motion control and included in the IEC 61800-7 standard, Adjustable speed electrical power drive systems — Part 7: Generic interface and use of […]
