Low Voltage AC Servo Technique for the Future 2
FEATURES High Resolution 16-bit Absolute Encoder 65,536 pulses/rev! A new 16-bit absolute encoder with 65,536 pulses per revolution is standard on all servo motors. 16-bit high resolution feedback increase motor smoothness and maintain dynamic performance under all speed/load characteristics. High speed 4-wire serial bus transmission with data redundancy check allows fast, accurate and reliable positioning. 4-Wire Interface Encoder feedback is achieved with only 4 wires - two for power and two for data. Making wiring both easy and reliable. Speed and Reliability 1.875MbPS speed with 8-bit CRC per data packet. Encoder Data Packet D01 D02 D03 D04 +5VDC S- S+ GND Header Position Data 16-bit CRC Fast Positioning Response High frequency response is key to achieving accurate and fast positioning. During development, the new DYN2 servo drive was tested under harsh instantaneous acceleration/deceleration profiles. The servo drive achieved outstanding 10ms position response. This fast and dynamic point-to-point servo positioning allows the new DYN2 servo drive to perform even in the most demanding applications. 10ms Command Reference Motor Position 90 Typical response of 200W servo motor given 90 (16,384p) instantaneous step command. Servo drive in position servo mode. Low Voltage DC Input Low voltage initiative with max. +75VDC input allow easy universal application into new or existing designs with DC power supplies. Low voltage is also safer for both user and machine. DC input requires less power draw and increases system efficiency by utilizing common DC bus voltage to minimize energy consumption. 3
FEATURES Industry Standard Control Input Standard pulse formats with photo-isolated interface. High pulse frequency capability and electronically scalable travel. Differential line receiver reduce transmission noise. Analog speed/ torque reference with ±10VDC voltage range. Pulse Reference PULSE + DIRECTION CW + CCW A + B PHASE QUADRATURE Analog Command -10VDC~+10VDC analog reference input for Speed and Torque servo control mode. Small Modular Size The new DYN2 servo drive sets an unprecedented package size for it`s class, measuring just 32mm wide, 85mm tall and 75mm deep. Multiple units can be arrayed with just 1mm in-between spacing to achieve efficient modular mounting. Instead of being designed into the system, the new DYN2 servo drive can simply be placed into the system. Simple and Effective I/O To maximize usability and application range, new input and output signals have been added. The I/O signals have been simplified down to key selections, with available custom selections for fast and easy integration. Standard outputs include Servo On Position, Zero Point Index, Servo Alarm and +5VDC supply. Standard inputs include command pulse/analog, Servo Enable, and Drive Reset. No matter the application, the new DYN2 servo drive has the relevant communication to meet requirements. 4
FEATURES High Motor Capacity The new DYN2 servo drive s highly efficient and reliable control technology allows for highest motor capacity pair than any other servo drive in it s class. The motor capacity selection reflect industry requirements including high speed or high torque choices, with 5,000rpm top speed and 7.2Nm (1020Oz-in) peak torque. Easy Set Up and Tuning Servo drive testing and tuning is all done through a simple RS232 or USB connection with a PC and the DMMDRV graphic interface communicates with the servo drive immediately. Tuning is simplified down to just a few parameters to give the user flexibility on servo behaviour. Internally, the servo drive adjusts parameters real time to maximize performance relative to user defined parameters. Each application calls for a different dynamic - the new DYN2 servo drive gives the user maximum control over the machine. PC Interface Flexible Tuning The new DYN2 servo drive s 3 gain parameters make tuning simple and flexible.
