Product Description:
The E4809-024-019-C is an accurate type-E absolute encoder pioneered and designed originally by Okuma for its wide variety of servo products. As an absolute encoder, this device is ideal for closed-loop servo control and systems. In a closed-loop system, a device is typically monitored at set frequencies to maintain a stable output or performance. Whenever the monitored device deviates from the target output, the monitoring system feeds the output back to a controller, which then adjusts the device parameters to meet a certain value. Since servomotors are typically integrated with an encoder, they only need a servo drive or controller to complete a closed-loop system.
Not all motors, however, come with a built-in encoder. For other motors without an integrated encoder, using separate encoders such as the E4809-024-019-C is essential. The E4809-024-019-C may be bought as an additional accessory or as a replacement to an existing encoder within a servomotor. In servo systems, a variety of encoders exist to meet different demands and applications. These servomotors may be classified according to their monitoring capabilities or monitoring schemes. The E4809-024-019-C, in particular, is an absolute multi-turn encoder, allowing it to precisely determine the position and motor speed at any time. Absolute encoders are ideal over incremental encoders whenever monitoring the shaft position is a priority.
The E4809-024-019-C is one of Okuma’s most compact absolute encoders. Although it does not come with its own housing or protective casing, it can fit most motor terminal boxes. For other motors, however, employing no encoder housing, a separate casing may need to be constructed to protect the absolute encoder during operation. For some applications, however, it may not be entirely necessary to construct a housing for the encoder, especially if the operating environment is ideal for general-purpose circuit boards.
Frequently Asked Questions about E4809-024-019-C:
Q: What is the difference between single-turn and multi-turn absolute encoders?
A: Absolute encoders such as the E4809-024-019-C can be multi-turn or single-turn encoders. The difference between the two is that multi-turn encoders can monitor the number of elapsed revolutions, whereas single-turn absolute encoders can only monitor precise position every single rotation.
Q: What is the main purpose of the E4809-024-019-C?
A: The E4809-024-019-C serves as an absolute encoder, which monitors important motor shaft parameters during operation.
Q: What are the typical parameters monitored by absolute encoders such as the E4809-024-019-C?
A: Absolute encoders such as the E4809-024-019-C can monitor speed, position, and torque during operation.
Q: What other devices does the E4809-024-019-C need to operate?
A: The E4809-024-019-C must first be connected to the motor and then to a servo drive for full closed-loop operation.
Q: How reliable is the E4809-024-019-C?
A: The E4809-024-019-C is one of Okuma’s most reliable servo encoders, offering high accuracy and operating range.
