Product Description

The Kollmorgen S7720A-PBF2-PM is a digital servo amplifier designed for performing complex drive tasks. If the device is used in residential or commercial areas, the user should implement additional filter measures. Only copper wires should be used to wire the unit. The cross-sections of the conductor can be derived from the standard IEC 60204 specifications. The use of the device is prohibited in the following environments: potentially explosive areas, environments with electrically conductive acids, alkaline solutions, vapors, oils, or dust, directly on non-grounded supply networks, on ships, or offshore applications.

If the storage period of the S700 digital servo amplifier crosses one year, its capacitors should be re-formed before setup and operation. This can be done by removing all the electrical connections and applying a single-phase 230 V AC for 30 minutes at the L1 and L2 terminals. The unit does not need any maintenance. If the casing of the product is dirty, the user can clean it with isopropanol. The device has a nameplate attached to its side. The amplifier is fully programmable via the RS232 interface. The unit has an enclosure protection rating of IP 20 in accordance with IEC 60529 specifications.

The switching frequency of the output stage of the S700 digital servo amplifier is 8 kHz. The unit’s permitted switch on/off frequency is 30 1/h. The rated input power of the servo amplifier for continuous operation is 50 kVA. It is crucial to ensure that the device is safely earthed to the PE busbar in the switchgear cabinet. There is a high risk of electric shock. Personal protection cannot be guaranteed without low-resistance earthing.
