Product Description

The Kollmorgen S7720A-SNF2-S4 is a digital servo amplifier that should be operated with a compatible servomotor. The device should be mounted on a conductive surface. The leakage current of the unit is more than 3.5 mA. The product has a nameplate attached to its housing. There is an LED display to indicate the status of the product. There are three slots on the servo amplifier. The first slot is equipped with the SynqNet expansion card, the second slot has the fan controller, and the third slot incorporates the safety card S2-2, SIL 2 expansion card. The repair of the device must be performed only by the manufacturer. Opening the unit voids the warranty.

The switching frequency of the output stage of the S700 digital servo amplifier is 8 kHz. The unit has a minimum motor inductance of 0.51 mH at 3x400 V. The depth of the device, without connectors, is 244 mm. The maximum ambient storage temperature of the product is +55°C. The dimensions of the amplifier are 390 x 600 x 400 mm. Its maximum stacking height is 3 cartons. The available documentation should be carefully read before the installation and commissioning of the device. Improper handling of the unit can result in damage to property and injury to people.

The S700 digital servo amplifier contains electrostatically sensitive components. These components are prone to damage if handled incorrectly. The user should discharge his or her body before touching the amplifier. The surface temperature of the product can exceed 80°C. When disconnecting connectors, there is a danger of electrical arcing. It is because capacitors can have dangerous voltages for nearly eight minutes even after the supply power is turned off.
