Customer-Driven Servo Design

August 08, 2016

The mid-level, general-purpose 1S Series Servos incorporate valuable input from our customers to optimize use from design to commissioning.

Lower Costs and Total Cost of Ownership

The 1S Series eliminates up to 20% of hidden servo system costs to the customer by no longer requiring separate external parts such as servodrive controller cable, terminal block for I/O, safety cable, brake relay and absolute encoder battery and cable.  Regardless of power rating, all 1S power drives have a uniform height to simplify design and improve control cabinet air circulation. We streamlined I/O connection, replacing an external terminal and cable with a pluggable connector with push-in terminals that allows wiring to be prepared separately. In the process, we increased the number and mix of supported I/O.  The end user benefits from lower maintenance costs.

Advances for High Accuracy Machines

The 1S servomotors use a gear-less/battery-less, multi-turn 23-bit absolute encoder, 16-bit multi-turn to provide accurate position input. Advanced tuning functions help shorten settling time, allowing faster production speeds and greater throughput.

Expanded Built-in Safety Capability

Machine safety for rotating hazards takes a prominent position in equipment design since the recent changes in injury liability. To help OEMs simplify safety system design and standardize on one series without stocking many separate drives, the 1S Series servodrives offer both networked and hardwired safe torque off built in. Configuration of FailSafe over EtherCAT (FSoE) only requires connecting NX Series safety control units to 1S Series servos  via open network "EtherCAT". No wiring is required for the emergency stop of each axis for servo.

First Wave of 1S Servos

The first wave satisfies 100 W to 3 kW applications. Future releases will address power requirements of higher and lower power ratings.
