SERVO CONTROLLER (WITH INTEGRATED POWERSTAGE)
Modern digital servoamplifiers are still used in central motion control architecture and are very often a replacement for obsolete analog amplifiers. Due to the powerful processors used in today's digital amplifiers it is possible to provide very useful software tools, including setup and tuning tools which makes life much easier for the user.
The available intelligence in these modern servo amplifiers can also be used to integrate more sophisticated tasks into the amplifier and make it a single axis motion controller including position control and indexer functionality.
Additionally many of the digital amplifiers of the latest generation are equipped with fieldbus interfaces like CANopen, Profibus, EtherCAT, etc. so that they also can be used in automation architectures with distributed intelligence (see also distributed control).
In general we can tell the following features for digital servo amplifiers:
- flexible regarding motor technology: AC brushless (BLDC) and brushed (DC) motors
- flexible regarding supply voltage: 3 x 400/230Vac, 1 x 115/230 Vac or DC-supply available
- efficient control: vector control (info sheet vector control
) - efficient setup: powerful software tools (often with oscilloscope and auto-tuning and auto-phasing)
- easy integration into central control architectures: +/-10V and/or PWM current or velocity commands
- easy replacement for stepper solutions: pulse/direction-interface as position command
- single axis controller: indexer and ASCII commands via RS232-interface (programs often also selectable by I/O)
- easy integration into distributed control architecture: several fieldbus interfaces available
We offer several product lines to be able to meet all requirements in various applications:
