Product Description

The S7720F-NANA-F2 is a digital servo amplifier produced by well-trained engineers of Kollmorgen according to international quality standards. This servo amplifier carries out the accurate control of the operation of servo motors according to configuration parameters. It is a flexible device that can be used with synchronous servo motors, linear motors, asynchronous motors, and DC motors. Unlike convectional servo amplifiers, the S7720F-NANA-F2 features a sophisticated and user-friendly display unit that can be used to monitor its operation in real time. Two pressure sensitive keys are also present on the amplifier housing, operators can use these keys to control the servo amplifier if a PC is not available. The S7720F-NANA-F2 digital servo amplifier can be used in commercial and residential areas, however the operation of the amplifier in these areas might require the integration of additional measures to prevent electrical interference.

The S7720F-NANA-F2 servo amplifier can be connected directly on a grounded 3-phase supply, the rated supply voltage it requires for optimum operation falls between about 208 to 480 volts. The rated input power required by the servo amplifier for continuous operation is about 50 kilovolts amperes while the rated DC bus link voltage falls between 290 to about 675 volts. The S7720F-NANA-F2 servo amplifier features a Fan Controller expansion card integrated into slot 3 on its front panel, this expansion card helps to reduce the noise generated by the amplifier during operation, it does this by stopping, or reducing the speed of the air blower built into the device.

The permissible ambient temperature suited for the operation of the servo amplifier falls between 0 to about 40 degree celsius, also the amplifier should be used at a relative humidity level of 85 percent.

Frequently Asked Questions about S7720F-NANA-F2

Q: What type of expansion card is integrated into the S7720F-NANA-F2?

A: The expansion card in the S7720F-NANA-F2 servo amplifier is the Fan controller card. The card helps to reduce the noise generated by the module.

Q: How does the S7720F-NANA-F2 respond to overtemperature?

A: During overtemperature, the S7720F-NANA-F2 servo amplifier automaticaly shutsdown to prevent damage. Proper ventilation must always be ensured in the housing of the amplifier.

Q: What maintenance operation is required by the S7720F-NANA-F2?

A: The S7720F-NANA-F2 servo amplifier does not require maintenance. Opening the device voids the warranty covering it.

Q: What is the service life of the S7720F-NANA-F2 servo amplifier?

A: The amplifier can maintain optimum operation for more than five years. However, this is only true if it is used according to the instructions in the documentation.

Q: Can operators exchange the parts of the S7720F-NANA-F2 amplifier with new ones?

A: The exchange of faulty parts of the ampliifer with new ones is allowed, however this should be done by a professional staff who is qualified in electrical engineering.
