S7720A-SNF2-S3

Product Description

The S7720A-SNF2-S3 is a digital servo amplifier from Kollmorgen that can be operated only as an integral part of an electrical plant or machine. The device has a memory card for firmware and parameter updates. The presence of connectors for all connections and the autotuning feature enables faster setup of the unit. The product can be supplied from a three-phase grounded industrial supply network. Only copper conductors must be used for wiring the device. The user can derive the conductor cross-sections from the standard IEC 60204 specifications. The product should be stored only in the original recyclable packaging supplied by the manufacturer.

The commissioning of the S700 digital servo amplifier is prohibited if the equipment in which it is installed does not fulfill the requirements of the EMC Directive, EC Machinery Directive, or Low Voltage Directive. The unit does not come with the motor over-temperature sensing feature. There is a nameplate attached to the side of the device. It carries the technical details of the amplifier. The product is fully programmable through the RS232 interface. The minimum motor inductance of the unit at 3x400 V is 0.51 mH. The product’s form factor for the output current is 1.01.

The storage humidity of the S700 digital servo amplifier is 5% to 95% without condensation. The device has a pollution level of 2 as per IEC 60664-1 specifications. The device has a built-in safety function, STO, which can be used to turn off the drive, eventually enabling functional safety at the drive shaft. There is a high risk of electrical arcing at the time of disconnecting the connectors. Proper care should be exercised, and only well-qualified personnel should handle the device.
