Product Description

The S74802-EIF2-F2 is a state-of-the-art digital servo amplifier designed by Kollmorgen according to international quality standards. The servo amplifier is produced for the accurate closed loop control of the speed, position, and torque output of industrial synchronous, asynchronous, and industrial motor designs. The servo amplifier meets the IP20 protection class, it is intended to be used as a integral component of electrical plants or machines. When combined with a compatible industrial motor, this servo drive amplifier can be used in a wide range of industrial applications including metal forming machines, robotics, transfer facilities and lots more. The servo amplifier is tested and certified to be absolutely safe for industrial operations, however operators of the amplifier are still required to be qualified and familiar with the safety instructions delivered with the device. The S74802-EIF2-F2 servo amplifier belongs to the overvoltage category III and can be supplied from a 3-phase grounded industrial supply network. Connection to other supply networks is possible, however this might require additional accessories for optimum operation. The rated supply voltage of this industrial servo amplifier falls between 208 to about 480 volts, at a frequency of 50 to 60 Hz. Also, the servo amplifier generates a rated output current of 48 amperes, although this can reach a maximum value of 96 amperes. During operation, the S74802-EIF2-F2 servo amplifier does not generate a noise emission that exceeds a 62 decibels. The S74802-EIF2-F2 servo amplifier features a three-phase LED display and two pressure sensitive keys through which it sends command instructions into the servo amplifier. The amplifier also features an internal air blower designed to regulate the operation temperature of the motor by maintaining a continuous circulation of cool air in the control cabinet.
