This is an A6 series AC servo motor and driver kit consisting of a 220VAC 400W motor with the built-in 17-bit multiturn absolute encoder and a 24V 7.3W brake, and a single-phase 220V 400W servo driver that supports PROFINET communication. The motor provides excellent servo control performance.
A key safety enhancement is the integrated Safe Torque Off (STO) function. This safety-critical feature prevents unexpected motor start-ups by securely disabling the torque output, significantly reducing the risk of injury to personnel or damage to equipment during installation, maintenance, or emergency stops.
This series of servo products is easy to operate, economical and efficient. It has the characteristics of high response, high precision, high speed, high synchronization, etc., supporting one-button self-tuning and automatic inertia detectionetc.
The A6-PN series servo products feature in high cost-efficiency and are compatible with popular PLCs from brands such as Beckhoff and Omron, providing efficient and convenient motion control solutions for various industries.

If you need longer motor and encoder cable combination, 5m or 10m options are available.

The default encoder in this servo motor can be used as a multi-turn absolute encoder, but it requires a 3m, 5m or 10m encoder cable which has a battery box.

If your power supply voltage is 110VAC, you need to use this transformer TR500-A220-A120 when using this servo motor.

How to choose the correct Type-C debugging cable? Please refer to this article.
