Product Description

The S74802-SNF2-NA is an advanced industrial servo amplifier manufactured by the Kollmorgen according to international quality and safety standards. This amplifier is a modular device that is intended for the control of the speed, position and torque output of industrial motors. The amplifier is designed exclusively for brushless synchronous, asynchronous, and DC servo motors. The S74802-SNF2-NA servo amplifier is required to be used in a close control cabinet that maintains permissible ambient temperature around the controller. Under normal operating conditions, this servo amplifier can be used in various industrial applications such as metal forming machines, food processing machines, paper converting machines, and lots more. The amplifier is intended for use with AC mains power supply, although the operation of the amplifier with DC mains is possible, users will be required to evaluate the DC installations for important parameters such as current rating, branch circuit protection, wire size, fuse protection, and system dielectric requirements. The S74802-SNF2-NA servo amplifier features both the CANopen and EtherCAT onboard, it can also support various motor feedback designs including Resolver, Encoder, AquadB encoder, and ComCoder. There slots for expansion cards are integrated into the front panel of this industrial servo ampliifer. A memory card slot is also present onboard. The permissible ambient temperature for the S74802-SNF2-NA industrial servo amplifier falls between 0 to about 40 degree Celsius, also this industrial amplifier should not be operated at a height that exceeds 1000 meters above sea level. During operation, the servo amplifier requires a rated supply voltage that falls between 280 to about 480 volts, also the rated input power required by the servo amplifier for continuous operation is about 35 kilovolts per ampere.
