Product Description

The S7720A-FBF2-PA is a digital servo amplifier launched by Kollmorgen. The device has three slots for expansion cards. The unit is equipped with the FB-2 to 1 expansion module in the first slot, the fan controller in the second slot, and the Posl/O-Monitor in the third slot. The product should always be mounted and operated in a closed control cabinet. If there is an excessively high temperature within the control cabinet, the servo amplifier automatically shuts down. Forced ventilation should be ensured within the cabinet.

Devices that produce magnetic fields must not be mounted directly beside the S700 digital servo amplifier because strong magnetic fields can directly affect the internal components. The rated DC bus link voltage of the unit is 290 to 675 V. The product has a peak output current of 140 Arms for approximately 5 seconds with a tolerance of +/- 3%. The switching frequency of the output stage of the product is 8 kHz. The available documentation should be read carefully before the installation and commissioning of the device. If the amplifier is not handled properly, it can cause damage to objects and harm to people.

Only well-qualified personnel are allowed to perform tasks like setup, transport, assembly, and maintenance. The qualified personnel should know and follow the IEC 60364 and IEC 60664 specifications as well as national accident prevention regulations. The user is not allowed to modify the unit without permission from the manufacturer. If the user opens the housing for any reason, all certificates will become invalid. If the permissible current values or voltage values of the amplifier are exceeded, it is likely to damage the device.
