Designed to meet the machine requirements, the 1S servo technology optimizes the full cycle, through the machine design, installation and commissioning tasks and finally to the maintenance once in production. In addition to the traditional motion solution, the 1S servo offers high resolution multi-turn encoder without battery backup, safety network built-in and improved loop control allowing accurate and higher machine productivity.

Functions:
1. 7-segment LED Display
A 2-digit 7-segment LED display shows error numbers, the Servo Drive status, and other information.

2. ID Switches
Two rotary switches (0 to F hex) are used to set the EtherCAT node address.

3. Charge Lamp
Lights when the main circuit power supply carries electric charge.

4. Control I/O Connector (CN1)
Used for connecting command input signals and I/O signals to an external device.

5. Encoder Connector (CN2)
Connector for the encoder installed in the Servomotor.

6. EtherCAT Communications Connectors (ECAT IN CN10, ECAT OUT CN11)
These connectors are for EtherCAT communications.

7. USB Connector (CN7)
USB-Micro B Communications connector for the computer. This connector enables USB 2.0 Full Speed (12 Mbps) communications.

8. Brake Interlock Connector (CN12)
Used for brake interlock signals.

9. Main Circuit Connector (CNA)
Connector for the main circuit power supply input, control power supply input, external regeneration resistor, and DC reactor.
