Product Description:

The Kollmorgen S7720C-SEF2-PM digital servo amplifier must have a warning indicating an automatic restart when it is powered on if the AENA parameter is set to 1. This servo amplifier has a residual voltage for 10 minutes after its disconnection from the power supply. The product comes fitted with EMC filters. This device encompasses a built-in fan with a protective grille for its ventilation. The unit is meant to be wired using 60 °C/ 75 °C copper wires. It must be taken care to ensure that its wiring is correct to minimize the possibility of it getting damaged. This amplifier has three LEDs on its SERCOS 2 expansion card.

The product can be assigned a drive address ranging from 0 to 63. This device related parameters can be modified using the DRIVEGUI.EXE setup software. The unit has no harmful substances in any of its components that can have an adverse impact on the environment with its operation. It uses fiber optic cables for connections to and from the SERCOS expansion card. This amplifier can be associated with a maximum of three feedback systems at a time.

The product cannot be used without a grounding connection. This device setup is to be undertaken only by personnel with expertise in drive technology and electrical engineering. The unit may have uncovered live sections according to its enclosure protection level. Its hardware must not be modified without permission from the manufacturer. This servo amplifier has several notes placed on its housing. The product can be supplied from TN systems with up to 42 kA symmetrical current rating.
