Product Description

The S7720F-SEF2-NA is a digital servo amplifier designed by Kollmorgen to carry out the accurate control of the speed, position and torque output of industrial motors used in production and processing systems. This servo motor is manufactured to be used exclusively with synchronous, asynchronous, and DC motor series. The housing of the servo amplifier is designed according to the IP20 protection class, however it is still necessary for the amplifier to be installed into an additional closed control cabinet that can provide protection that meets at least the IP54 category. Unlike convectional industrial machines, it is possible to use this digital servo amplifier in residential or commercial areas, however this will require additional measures to prevent electrical interference.

The S7720F-SEF2-NA is integrated with two main expansion cards designed to extend its functionality. The expansion cards present in the motor includes the SERCOS II expansion card and the Fan controller expansion card. The rated supply voltage required by the S7720F-SEF2-NA servo amplifier falls between 208 to about 480 volts, also the current rating of this amplifier is 72 amperes. The S7720F-SEF2-NA servo amplifier features a built-in air blower that protects it from overtemperature damage by dissipating excess heat from its housing via forced ventilation.

A 3-character LED display unit is integrated into the housing of this servo amplifier, the display unit provides operators with a user friendly way of monitoring the operation of the servo amplifier. Error, and warning messages are displayed through the LED display unit through short codes. The S7720F-SEF2-NA servo amplifier is compatible with numerous feedback systems, example of compatible feedbacks include resolver, Hall, SSI, sensorless, and the Encoder ENDAT2.1. The total weight of the amplifier is 13 kilograms.
