The SSDC series is a high performance, intelligent Step-Servo system with multi-axes field bus control.Enhancing a stepper motor with servo technology has created a product with exceptional features and broad capability. It supports pulse/direction control, analog control and multiple field bus controls such as Modbus, CANopen, SCL/eSCL commands, EtherNet/IP and EtherCAT protocol. And the SSDC series also supports the stand alone function(Q programmer) called by field bus control.
■ Multi-functional Capability
■ Closed-Loop Control
• Closed-loop Step-Servo mode
The step servo motor has a built-in high-resolution intelligent encoder. In addition to providing customers with accurate positioning, the drive can automatically identify the motor model and motor parameters after connecting the smart encoder motor, eliminating the need for motor configuration steps. At the same time, a drive can be compatible with a variety of intelligent encoder motors, and has two resolution encoders 20000 pulses/revolution and 4096 pulses/revolution to choose from, and it can also support multiple closed-loop control modes. Ordinary encoders only have A/B signals, and the initial alignment of the motor is achieved by energizing the motor windings and locking the shaft. If there is no friction load, the lock shaft alignment is more accurate. However, if there is a friction load (such as the application of a vertical axis), the initial alignment will produce an electrical angle error, which will cause a torque loss. The greater the friction load, the greater the torque loss. When the frictional load is large to a certain degree, it may cause the motor to fail to run or even speed up. In addition to the A/B signal, the intelligent encoder mounted on the MOONS' step servo motor also has an auxiliary positioning signal. The drive can know the exact position of the motor in real time. Even if there is a friction load, there will be no electrical angle error, and there will be no loss of torque.
• Closed-loop Step-Servo mode
Position, velocity and current closed loop control. Precisely position and velocity control can match the harsh applications. Adjust the current in real time according to the actual load situation. Highly robust servo control accommodates a wide range of inertial loads and friction load changes.
• Closed-loop Step mode
Position Closed-loop control. No tuning, no vibration,stall prevention. This mode is suitable for some special applications where the vibration is particularly demanding, such as vision systems, nano-technology, semiconductor manufacturing, ink jet printers, and so on.
• Full Closed-loop mode - 2-way feedback
Support 2-way feedback, one way connect to the motor encoder position feedback, the other way connect to the load side position feedback, to avoid the position error caused by the mechanical error of the transmission mechanism, to achieve more precisely position control. Load side feedback support: single-ended or differential incremental encoder, scale.
■ Safe & Convenient
• Support communication and motor power cables disconnection protection - Make equipments safer • Support on-line configuration by fieldbus - Make operation more convenient
■ Low Heating / High Efficiency
• The SSDC uses only the current required by the application, generating minimum heat output. • When the motor is not moving, the current can be nearly zero resulting in extremely low heat output. • Being able to use almost 100% of the available torque allows for more efficient operation and may allow a smaller motor size.
■ Smooth & Accurate
• Space vector current control with a high resolution encoder gives smooth and quiet operation, especially at low speeds - a feature not found with traditional stepper motors. • High stiffness due to the nature of the stepper motor combined with the highly responsive servo control results in accurate position control both while running and when standing still.
■ Fast Response
When performing fast point-to-point moves, the high torque output and advanced servo control provides a very responsive system far exceeding what can be done with a conventional stepper system.
■ High Torque
• Because the TSM operates in full servo mode, all the available torque of the motor can be used. The motor can provide as much as 50% more torque in many applications. • High torque capability often eliminates the need for gear reduction. • Boost torque capability can provide as much as 50% more torque for short, quick moves.
■ Motion Monitoring
• For applications where extreme real-time motion is critical, the Step-Servo Quick Tuner provides a simple and practical tool for monitoring actual motion trajectories. • It can be used to monitor common metrics such as actual velocity and position error to assess the current actual performance of the system. • An interactive monitoring and tuning interface provides the fastest possible performance output.
■ Easy Tuning
• Pre-defined tuning parameters quickly allow maximum control performance and stability. • A selection list provides an easy method to achieve the desired level of control. • In most cases NO extra manual tuning is required. • There is no need to do tuning in closed- step mode.
