Product Description

The S7720C-DNF2-PM digital servo amplifier from Kollmorgen must be free of stress during the operation phase. This servo amplifier must be used in commercial enterprises or residential areas only after implementing additional filter measures. The product must not have a transient overvoltage of more than 1000 V between its outer conductors for less than 50 µs. This device features a pollution level 2 according to EN 60664-1 specifications. This device may get destroyed if the DC bus link voltages are different. The unit that works generatively often should be placed near an amplifier that needs energy. It is possible to connect an external brake resistor at the X8 connector. This amplifier produces a high DC voltage of up to 900 V when it is operated.

The product protects the connected motor from overloading when the thermal protection sensor is connected and its parameters have been set correctly. This device supports up to three feedback systems at a time. The unit needs start-up information for the integrated position controller whenever the 24 V auxiliary voltage is turned on if a 5 V incremental encoder is used. It is important to ensure that when unshielded cores are used, the cable length is not more than 500 mm.

This amplifier has a rated output current of 72 Arms with a tolerance of +/-3%. The product features a BTB/RTO output relay contact with a maximum voltage rating of 30 VDC / 42 VAC and a current rating of 500 mA. This device shuts down after displaying the F01 or F13 code when the temperature inside the cabinet is very high. The unit depicts a 4 A current rating for its 24 V electronics. Its motor cable has a capacitance of less than 150 pF/m. This servo amplifier offers fast feedback evaluation.
