Product Description:
The S74802-SEF2-NA is an highly advanced servo amplifier produced by Kollmorgen to carry out the closed loop control of the speed, position and torque output of brushless synchronous, asynchronous, and DC motors used in production and processing applications. This industrial servo amplifier is a modular device that meets the IP20 protection class, the amplifier also requires installation into a closed control cabinet that can provide it with optimum protection against both solid and liquid foreign substances. The S74802-SEF2-NA servo amplifier is a very flexible device, when combined with a compatible motor design, it can be used in a wide range of industrial applications including metal forming machines, food processing machines packaging machines and textile machines. The digital servo amplifier is also designed to be perfectly safe for industrial applications, before it is delivered to the end user, it is tested and certified to meet the highest standards of operational efficiency and safety. The rated output current generated by the S74802-SEF2-NA servo amplifier during operation is about 48 amperes, however the servo amplifier can generate an output current as high as 96 amperes. Also, the amplifier requires a rated supply voltage that falls between 208 to about 480 volts. The S74802-SEF2-NA is delivered as a standard device of the highest quality, the modification of the servo amplifier without permission by the manufacturer is not permitted. The opening of the housing of the amplifier causes loss of warranty, and all certificates of the device becomes invalid. Operators are required to pay close attention to the warning signs that are added to the device housing, if these signs are damaged, they must be replaced immediately to prevent accidents.
Frequently Asked Questions about S74802-SEF2-NA:
Q: What type of connection should be used for the earthing of the S74802-SEF2-NA digital servo amplifier.
A: Since the leakage current of the S74802-SEF2-NA servo amplifier is more than 3.5millimaperes, the earthing connection must either be doubled or with a cross section greater than 10millimeters
Q: When should the S74802-SEF2-NA servo amplifier be operated with an isolating transformer?
A: Isolating transformers are necessary to be used with the S74802-SEF2-NA when protection against indirect contact is needed. Or when an alternative form of shock harzard is needed.
Q: Is the S74802-SEF2-NA servo amplifier affected by magnetic fields?
A: Yes. Operators should avoid mounting devices that produce a high magnetic field driectly beside the servo amplifier. These type of devices should be installed away from the amplifier.
Q: How does the S74802-SEF2-NA handle overheating?
A: In the case of overheating, the S74802-SEF2-NA servo amplifier will switch-off itself to prevent damage. An adequate flow of cool air should be ensured to prevent overheating around the amplifier.
Q: Can the settings of the S74802-SEF2-NA be changed to meet specific industrial applications?
A: It is permissible to use the setup software to alter the settings of the servo amplifier. Any other alterations will invalidate the warranty covering the device.
