Product Description

The S7720C-EIF2-S3 digital servo amplifier from Kollmorgen triggers electric shock if it is not EMC grounded properly. This servo amplifier along with the filter and choke must be assembled as close as possible to each other on the conductive and grounded mounting plate inside the control cabinet. The product has live electrical connections when it is being operated. This device comprises capacitors with dangerous voltages for 10 minutes in its DC bus link after the power has been turned off. The unit has a BTB/RTO contact that must be wired in series into the emergency off circuit. Its feedback lines should not be extended as this can disturb the signal processing.

This amplifier has a RS 232 serial interface at the X6 connector to connect to a PC. The product must be wired and installed only when it is not in the live state. This device has a shielding connection on the front panel. The unit must not be modified by the user. It is recommended to use the manufacturer's cables for its connection.

This servo amplifier portrays the slots for the expansion cards on the front panel. The product can be directly connected to a three-phase supply network through the X0 connector. This device must be positioned near an amplifier that needs energy if it operates in the regenerative mode often. The unit can be associated with an external brake resistor at the X8 connector. It supports several common feedbacks for which the functions can be assigned through parameters.
