System description:
The Vector Control functionality is matched to the drive system requirements. The vector current control enables fast current injection into the motor windings in conjunction with short sampling times. The related highly dynamic build-up of the torque provides a good basis for higher-level closed-loop control circuits.
It is possible to choose between current control types and U/f controls. The control type U/f control can be used to operate both synchronous and asynchronous motors. The current control types are available both without and with various different encoder types for speed acquisition for asynchronous motors.
As a special application, externally excited synchronous machines can be operated in control type speed control with encoders (current control type).
The Vector Control functionality is available both in converter and inverter modules which are designed for a line voltage range of 380 V -15 % to 480 V + 10 %.
All units are provided with a comprehensive basic functionality which can be expanded, if required, by extensive technology and communication functions by the use of software and hardware options.
This enables the units to be adapted to the most diversified conditions of service. All closed-loop control functions are implemented with freely assignable function blocks which can be combined as desired. This enables the software to be flexibly adapted to various applications.
Menu structures stored in the unit software simplify start-up and visualization of the drives in conjunction with various operator control panels. PC-assisted tools enable effective parameter setting and data security.
