Product Description

The S7720F-NAF2-PM is a new-generation digital servo amplifier produced by well trained engineers of Kollmorgen according to international quality standards. The servo amplifier is a maintenance free device that maintains an accurate control over the speed, position and torque output of industrial motor. Also, this industrial servo amplifier has a modular design with an enclosure that provides protection that meets the IP20 protection category, this low protection classification of the servo amplifier makes it necessary for it to be installed in an additional closed loop control cabinet before it is switched on for operation. The S7720F-NAF2-PM servo amplifier is delivered as a standard device, it is delivered with a DRIVEGUI.EXE software module on a CD-ROM. The software module can be used to modify the operation of the servo amplifier according to the application requirements.

The S7720F-NAF2-PM servo amplifier features a built-in air blower which functions to dissipate excess heat from its housing unit via forced ventilation. It is important to ensure proper ventilation around the servo amplifier as it will automatically shutdown if there is a risk of sudden machine breakdown. The rated supply voltage of this industrial servo amplifier is between 280 to about 480 volts, also the input power required by the servo amplifier for continuous operation is about 50 kilowatts amperes. The S7720F-NAF2-PM servo amplifier has a current rating of 72 amperes, it can however generate a maximum output current of 140 amperes for a duration of approximately 5 seconds>>.

The permissible ambient temperature for the operation of the S7720F-NAF2-PM servo amplifier is between 0 to about 40 degrees, also the maximum permissible installation height for the amplifier is about 1000 meters above sea level.
