GE AF-650 GP - Signal Test Board Usage

Protection and Features:
• Electronic thermal motor protection against overload.
• Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a predefined level. An overload temper-
ature cannot be reset until the temperature of the heatsink is below the values stated in the tables on the following pages (Guideline - these temperatures
may vary for different power sizes, Unit Sizes, enclosure ratings etc.).
• The frequency converter is protected against short-circuits on motor terminals U, V, W.
• If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
• Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit voltage is too low or too high.
• The frequency converter constantly checks for critical levels of internal temperature, load current, high voltage on the intermediate circuit and low motor
speeds. As a response to a critical level, the frequency converter can adjust the switching frequency and/ or change the switching pattern in order to
ensure the performance of the drive.

1) Terminals 27 and 29 can also be programmed as output.
2) Terminal 37 is only available in AF-650 GP. It can only be used as safe stop input. Terminal 37 is suitable for category 3 installations according to EN 954-1 (safe
stop according to category 0 EN 60204-1) as required by the EU Machinery Directive 98/37/EC. Terminal 37 and the Safe Stop function are designed in conformance
with EN 60204-1, EN 50178, EN 61800-2, EN 61800-3, and EN 954-1. For correct and safe use of the Safe Stop function follow the related information and instructions
in the AF-650 GP Design Guide.
