Product Description

The S7720F-NAF2-S3 is a best-in-class digital servo amplifier from Kollmorgen. The servo drive comes with extended functionality. It is ideal for complex drive tasks. The unit features great autotuning and cogging suppression qualities. The product is generally intended for use in industrial environments. However, if it is used in residential environments, care should be taken to ensure that additional filter measures are implemented. The device must be operated only in a closed control cabinet. The ambient operating conditions should be considered when operating, storing, and transporting the unit. The product documentation contains all the information necessary to handle the equipment.

The S700 digital servo amplifier contains a fan controller in the second slot and a safety card S1-2, SIL 3 in the third slot. Coated PCBs are its mechanical/electrical option. The unit has a current rating of 72 Arms and a voltage rating of 208 to 480 V. The periodic overvoltage between the L1, L2, and L3 phases and the amplifier’s housing should not exceed 1000 V crest. The control of the holding brake alone cannot be used in applications, especially in cases where functional safety must be ensured with the brake. The maximum transport humidity of the servo amplifier is 95%. Condensation is not allowed.

Care should be exercised to ensure that the servo amplifier does not come into contact with plastic films, artificial fabrics, or other highly insulating materials. The product should always be placed on a conductive surface. The ambient storage temperature of the unit is -25 to +55°C. In general, the product does not require any maintenance. It must be noted that opening the amplifier for any reason invalidates the warranty.
