Product Description

The Kollmorgen S7720F-PNF2-S3 is an efficient digital servo amplifier that has a fan controller and safety card S1-2, SIL 3 expansion cards in its second and third slots respectively. The device has a voltage rating of 208 to 480 V. There is a name plate for identification. The nameplate also carries the technical details of the unit. Only well-qualified personnel should perform tasks such as transport, assembly, setup, and maintenance. They should know and follow IEC 60364 / IEC 60664 and relevant national accident prevention regulations.

The surface temperature of the S700 digital servo amplifier can exceed 80°C. So, before touching it, measure the temperature and wait until the machine has cooled down below 40°C. The unit should be placed on a conductive surface. The product can be mounted in a vertical orientation. There is an in-built fan for cooling. The fan comes with a protective grill, which can be cleaned using a dry brush. The servo amplifier should be mounted in a closed control cabinet. The device must be protected from impermissible stress. It should not come into contact with electronic contacts and components.

The servo amplifier has an Emergency Off function, which is used to turn off the machine’s electrical power supply. This protects users from any danger from electrical energy. The functional aspects of the Emergency Off function are defined in IEC 60364-5-53. A three-character LED display shows the operating status of the device. When the front panel keys are used, the function and parameter numbers and numbers for any warnings and errors are shown. The ambient operating temperature of the product is +40°C to +55°C with a power derating of 2.5%/K.
