Product Description

The GADSE03LB22 is a servo amplifier manufactured by Sanyo Denki. The series to which this module belongs is G Sanmotion AC Servo Amplifiers. It is a critical component for servo motor control related work in industrial automation and other control systems.

This GADSE03LB22 Servo Amplifier is created for industrial environments where vibrations and occasional shocks may occur that ensures reliability in machinery with dynamic motion. It is able to withstand mechanical shocks up to 20 meters per second squared without any functional degradation or damage. This module responds to control signals up to 3500 Hertz, which represents its bandwidth or responsiveness. This much higher frequency response means faster and more precise servo motor control which is relevant for applications requiring high speed positioning and dynamic motion. It is highly capable to manage loads with inertia up to 10 times the motor rotor’s inertia. This product does not contain a built-in regenerative resistor to dissipate excess energy during deceleration. While it is featuring an external dynamic braking resistor that helps dissipate excess regenerative energy generated when the motor slows down rapidly which prevents damage to the amplifier.

This GADSE03LB22 servo amplifier higher allowable inertia ratio means it can handle larger or heavier loads without losing precision or causing instability. The type of output signals this model provides for external devices is sourcing type which means it provides output signals to the connected devices. The continuous current that it supplies to the motor is 5.2 Arms. This specification means the product can reliably provide this level of current without overheating that defines its capacity for medium duty motor applications. This module also allows for easy switching between different control modes such as position, speed and torque control through softwares or external commands.

Frequently Asked Questions about GADSE03LB22


Q: How does the high-speed response of 3500 Hz benefit the GADSE03LB22 servo amplifier?

A: The 3500 Hz frequency response allows fast signal processing, ensuring precise and high-speed motion control. This makes the GADSE03LB22 ideal for applications requiring rapid acceleration and deceleration.

Q: Why is an external dynamic braking resistor used in the GADSE03LB22 instead of a built-in one?

A: The external DB resistor allows customized energy dissipation based on system needs. This feature helps in efficient braking without overloading the servo amplifier’s internal circuitry.

Q: How does the 10x allowable inertia ratio improve system performance in the GADSE03LB22 Servo Amplifier?

A: A higher inertia ratio allows the servo amplifier to handle larger loads without instability. This ensures smooth and controlled motion in applications with varying load sizes.

Q: What advantages does sourcing-type output provide in the GADSE03LB22 for external devices?

A: The sourcing-type output supplies power to external connected devices, ensuring reliable signal transmission. This configuration is commonly used in PLC and industrial automation systems for efficient communication.

Q: How does the GADSE03LB22 maintain performance when switching between position, speed, and torque control?

A: The amplifier supports dynamic switching via software or external commands, ensuring seamless transitions between modes. This flexibility is crucial for applications requiring precise control across different motion parameters.
