    Description

    Many motor and drive systems require a clamp circuit to limit increases in bus voltage when the motor is decelerating under load. This is commonly referred to as regeneration, and occurs when DC motors are driven by their load (back driving). During regeneration the DC motor can produce enough voltage to actually exceed the input power supply voltage. Applied Motion drives handle regeneration by directing this increased motor voltage back to the DC connection. However, if the voltage is not clamped to a safe level then the power supply and/or drive can be damaged. This regen clamp provides over-voltage protection for regulated power supplies by continuously monitoring and comparing the power supply voltage to the voltage present at the drive's DC connection. This design handles any DC voltage level within the specified range, making the RC880 a universal shunt regulation solution.

    Precautions for Using

    Braking Resistors Do not use resistors with a power rating below 50W and a resistance of 10 ohms, as such resistors are prone to overheating and damage. Additionally, the Regen terminal is a high-voltage port. Ensure that the drive is powered off before making connections, and take precautions against electric leakage to prevent harm to personnel and equipment. Regen Using the braking resistor (RC880) from MOONS' (as shown in the figure below) can effectively address the issue of regenerative discharge. To determine if there is a problem with regenerative power in your application, connect the braking resistor (RC880) in series between the drive and the power supply. If the "Regen" LED indicator on the RC880 never flashes, it indicates that there is no excessive counter-electromotive force in the circuit, and the use of RC880 is unnecessary. Precautions for Using
