Forestville, CA – The RVC-9025 Rotational Voice Coil Stage provides a means to quickly and accurately set an angular position. The frequency is factory adjusted to customer specifications during the manufacturing process. Amplitude of the resonating mirror can be adjusted through either an analog input voltage or the USB interface.

An optional high-resolution position feedback sensor can be monitored by an analog output signal on the User Connector. The RS-25 Resonant Scanner can also be configured with a high-resolution 16-bit Analog to Digital Converter to quickly sample and report the mirror position at any moment if the position sensor is included.

Van Nuys, CA — Motion Control – Moticont has added another non-commutated linear actuator to its DDLM series of low cost actuators.

The 0.125 in. (3.2 mm) diameter shaft has an internal thread on each end, a total of length of 4.960 in (126.0 mm), and extends 1.585 in. (40.3 mm) past the mounting end of the actuator. The shaft extends thru the 3/8-32 UNF x 0.250 (6.4 mm) long threaded studs at each end of the housing which can be used for mounting the DDL-019-070-01 linear actuator. Long life plain linear bearings support the internal shaft at both end of the actuator.

Motion Control – Customer Driven AC Servo Design

Motion Control Servo System

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.
