Product Description

The S7720C-FBF2-NA Kollmorgen digital servo amplifier functions like an adjustable digital speed controller for 62.5 µs. The servo amplifier has two direction selectable digital inputs/outputs. This product needs only a small-size switchgear cabinet for its installation because of the integrated power supply. The device supports a maximum site altitude of 1000 m above sea level without restriction. This unit is not UL Listed. It should be ensured that there is sufficient forced ventilation inside the switchgear cabinet. The amplifier is prone to condensation if the difference between the cooling plate temperature and the environment temperature is more than 10 K.

This product displays the error and fault codes encountered during operation on the LED display. The device can be coupled through the DC bus link if there are several amplifiers. The unit can be fitted with external brake resistor has a resistance of 10 Ohms. It comprises a special switching off procedure for the output stage if the holding brake function is enabled.

This servo amplifier behaves according to how various parameters have been set. The product stops the machine in which it is installed in normal operation using the Stop function. This device can implement the stop and emergency stop categories only if the STOPMODE and ACTFAULT parameters are set to 1. The unit needs an enclosure with at least an IP 54 protection category for its installation. Its STO inputs have an input voltage rating of 20 V to 30 V. This amplifier has separate switching paths for its STO enable inputs.
