Product Description

The Kollmorgen S7720A-NANA-PA is a digital servo amplifier in the S700 series. The device should be mounted in a vertical position. The current rating of the unit is 72 Arms. The product incorporates the Posl/O-Monitor expansion card in its third slot. This card provides an extra SubD connector (X5) featuring high-speed, bidirectional digital 5 V inputs and outputs and an additional X3C with analog +/-10 V inputs and outputs. The product should always be mounted on a conductive surface. Only copper wires must be used for wiring the device.

Correct wiring is mandatory for the proper functioning of the machine. The control and power cables must be routed separately, with a minimum distance of 200 mm. This setup improves interference immunity. The unit’s behavior is dependent on the current setting of the different parameters. On the top of the device, there is a card reader intended for memory cards. The firmware and the different parameters can be stored on the memory card. The product supports MMC and SD cards. The permissible storage temperature of the unit is -25 to +55°C.

The permitted switch on/off frequency of the S700 digital servo amplifier is 30 1/h. The device has a rated DC bus link voltage of 290 – 675 V. If the permissible current or voltage values of the product are exceeded, the unit can be damaged. The operator should ensure that everyone who is entrusted to work on the device has read and understood the product manual and that the safety notices and precautions mentioned are observed. The technical data and the various specifications listed in the connection conditions in the rating plate and documentation must be strictly followed.
