Product Description:
The PMDSB1S3P20 Motor Driver of Sanyo Denki is built for precision and durability as it operates on a stable 5V control supply and withstanding high-voltage stress up to AC500V for one minute. This servo drive module ensures safe integration into a wide range of control systems.
The PMDSB1S3P20 motor driver performs reliably in surroundings where the temperature remains within the range of 0 to 50 degrees Celsius without derating or thermal shutdown. It includes features such as automatic reduction of current during idle periods, customizable angular movement per step and selectable methods for receiving pulse signals. The primary power input for the module operates on 24 volts DC which allows a variation of 10% either way which is used for driving the motor and powering high-current sections of the circuit. It has a strong structural durability and it remains unaffected by external shocks or mechanical impacts as its impact resistance is in accordance with the criteria specified under section 3.2.2 of the NDS-C-0110 specification. It can run under moderate to high levels of relative humidity between 35% and 85% provided that moisture does not condense on internal components. It is designed to endure continuous oscillations with an acceleration of 0.5 times gravity over a frequency span of 10 to 55 hertz.
The PMDSB1S3P20 motor driver adheres to the UL508C certification which is a standard governing the safety of industrial control equipment, particularly for motor control devices. The resistance between internal circuits and ground or housing is no less than 10 megaohms when it is tested with a 500-volt direct current insulation meter. It can withstand ambient temperatures as low as minus 20 degrees Celsius and as high as 70 degrees Celsius without degradation or performance loss when later activated.
Frequently Asked Questions about PMDSB1S3P20:
Q: Why is the auto current down function important in the PMDSB1S3P20 motor driver?
A: It minimizes energy consumption and reduces heat generation during motor idle times. This extends the operational life of both the driver and the motor.
Q: How does the 10MΩ insulation resistance benefit the PMDSB1S3P20 driver in real-world applications?
A: It provides strong electrical isolation, reducing the risk of short circuits. This ensures safer performance in high-noise or sensitive environments.
Q: Why is vibration resistance tested across all three axes in this driver?
A: It ensures mechanical stability during continuous operation. This is especially critical in applications with dynamic or unstable mounting conditions.
Q: How do selectable pulse input methods improve integration with controllers?
A: It allows compatibility with a variety of control systems. Users can tailor the input method to match specific motion profiles or interface requirements.
Q: What’s the purpose of supporting a ±10% tolerance in the 24VDC input for PMDSB1S3P20?
A: It ensures reliable performance despite power supply fluctuations. This is crucial for installations where exact voltage regulation may not be guaranteed.
