Frequency inverter
Fiber optic-based Servolink 4 drive bus interface
From the third quarter of 2019, Sieb & Meyer will be equipping the SD2B plus frequency inverter with a fiber optic-based Servolink 4 drive bus interface as standard.
This means that the device can be used in conjunction with the MC2 motion controller for micrometer-precise positioning applications. One possible application is, for example, axes that perform focusing in machines for the direct exposure of printed circuit boards. In addition, the new interface also enables the device to be integrated into the Profibus/Profinet/EtherCAT fieldbus level using a gateway.
In the high-speed range, the SD2B plus frequency inverter enables sensor-based control based on TTL encoders. This allows several high-speed motors up to a speed of 120,000 rpm to be operated synchronously in master/slave mode, which is helpful in the field of optical systems, for example. The robust speed control also allows high mass inertia ratios between motor and tool of up to 1:100.
The SD2B plus has an IP20 housing and is characterized by its compact design. It has the STO safety function and an internal logic power supply. In addition to two TTL encoder inputs and outputs, five digital inputs/outputs and a USB interface are available.
