Product Description

The S7720F-2CF2-F2 is an industrial servo amplifier produced by Kollmorgen for driving suitable brushless synchronous servomotors, asynchronous motors, and DC motors. The servo amplifier accurately controls the torque, speed, and position of connected servo motors according to predetermined configuration parameters. The servo amplifier belongs to the overvoltage category III according to EN 61800-5-1 and can be supplied from 3-phase grounded industrial supply networks such as the TN-system, and the TT-system with a grounded neutral point. Also, the servo amplifier can be used with DC mains input power, however the DC installation much be reviewed and evaluated by the user for branch circuit production, wire size, wire voltage rating, fuse protection, system dielectric requirements, overvoltage, and input current rating.

The S7720F-2CF2-F2 servo amplifier operates with a rated supply voltage of 208 to 480 volts, also the rated input power required by the amplifier for continuous operation is about 50 kilovolts amperes. An air blower is built into the housing of the amplifier, the air blower protects the amplifier from overtemperature by dissipating excess heat via forced ventilation. The current rating of the servo amplifier is 72 amperes, while the maximum output current is about 140 amperes.

The servo amplifier belongs to the IP20 protection class, and it requires installation into an additional closed control cabinet before it can be switched on for operation. A 3-chracter LED display is integrated into the front panel of the servo amplifier, this display provides the operators with a user-friendly interface to monitor the operation status of the servo amplifier in real time. Error and diagnostic messages are displayed through the use of special LED diodes. The total weight of the amplifier is 13 kilograms.
