The servo amplifier is the master control device of the servo system. The motor control signals are sent via it. It is the servo amplifier that analyses any external impulses, adjusting the movement of the motor. The programming of the servo amplifiers is done in the same way as with inverters - you have to define the relevant values in special parameters segmented into groups. With the Astraada SRV-64 servo inverters, programming and parameter configuration is very simple. In the freeware Astraada DRIVE Studio, the parameters are presented in the form of an intuitive table with full descriptions of the individual values. This eliminates the need to use an external parameter list in the documentation. Communication with the software takes place via USB cable on a plug-and-play basis, without unnecessary link configurations.

 

Hardware features

Modbus RTU communication

The servo amplifier in the standard version has the ability to communicate in the most popular communication protocol in industry - Modbus RTU. Each parameter has a dedicated address that you can refer to in order to change its value. Communication also allows key parameters to be monitored, such as speed, acceleration, current position, current consumption and diagnostic messages to be sent.

Connecting an external encoder

Some installations require the use of an additional encoder. Astraada SRV-64 servo amplifiers in the standard version can support such an external encoder. The device will treat the additional sensor as a master and adapt to its readings in follower mode. You can define the rotation ratio of the external encoder to that of the one built into the motor.

Pulse-Direct control

In addition to the classic communication protocol, the standard version of the Astraada SRV-64 servo amplifier also supports simple pulse-direct control (pol. step-direction control). The servo amplifier in this mode is controlled on the basis of pulse signals going to the specially programmed high-frequency inputs of the servo amplifier.
