Product Description

The Kollmorgen S7720A-2CF2-S4 is a digital servo amplifier in the S700 series. It is a safety component built into an electrical plant or machine. The device is meant for use in industrial environments. If it is used in non-industrial environments, additional filter measures should be implemented. The unit contains electrostatically sensitive components. So, it should be handled appropriately to avoid damage. Only the manufacturer can repair the product. If the user opens the device, it will result in a loss of warranty. The device is controlled by digital means. The amplifier has a pollution level of 2 in accordance with IEC 60664-1 specifications.

The mounting position of the S700 digital servo amplifier is vertical. The device shuts down automatically if the temperature is excessively high in the control cabinet. The built-in safety function STO has two channels. It can be used to turn off the drive, thereby ensuring functional safety at the drive shaft. The Emergency Stop function of the unit is used to shut down the machine quickly in a dangerous situation. The function is defined by IEC 60204 specifications. The principles of the emergency stop devices and functional aspects are specified in ISO 13850.

The setup software can be used to alter the settings of the S700 digital servo amplifier. However, any other alterations seem to void the warranty. There is a risk of electrical shock with serious injury or death to personnel if the amplifier is not grounded properly. An isolating transformer is needed for 400V to 480V networks, which are asymmetrically earthed or not earthed. The leakage current of the unit is more than 3.5 mA.
