Product Description

The S7720-SNF2-NA digital servo amplifier by Kollmorgen is used in a drive system along with a motor. This servo amplifier has a standard Safe Torque Off function. The product comes with Ethernet connectivity option. This device depicts a rated line power of 50 kVA for S1 operation. The unit is controlled by a secondary feedback system when the electronic gearing functionality is implemented. Its Synqnet expansion card comprises hexadecimal node ID switches to set the main and low significant bytes. This amplifier can be connected to a third-party stepper-motor controller.

The product has an input resistance of 150 kOhms for its programmable differential analog inputs. This device must be operated with the doors of its control cabinet in the closed state. The unit is capable of supporting master-slave operation. It encompasses capacitors in its DC bus link circuit that must be reformed when the storage period of the amplifier is more than a year. This amplifier has a LED display that can highlight three characters at a time.

The product has no customization. This device has two STO enable inputs. The unit is meant to be operated at a temperature that ranges from 0 °C to 40 °C. Its bus cable must have an impedance of 120 Ohms to meet ISO 11898 specifications. This servo amplifier related mating connectors have to be obtained separately. This product features two channels for its STO function. The device may cause minor burns if its surface is touched when its operation takes place. The unit is not intended to be modified.
