Glentek’s SynqNetÔ Digital PWM Servo Amplifiers

Description

Glentek’s Omega-SynqNetÔ Digital PWM Servo Amplifiers offer the latest in DSP control of rotary and linear, brush and brushless, servo motors combined with the power and flexibility of the SynqNetÔ Network. The Omega-SynqNetÔ amplifiers feature one of the industry’s highest PWM update rates (24kHz) for superior bandwidth and are designed for high performance OEM applications. These amplifiers are available in a variety of power ranges and can be configured to operate from 24-370 VDC or directly from 110-130 VAC or 208-240 VAC main lines. They accept a wide range of incremental encoder inputs including inexpensive, low-resolution encoders, reduced wire encoders, and fine-pitch linear scales and all models include dedicated optically isolated I/O (limits, enable, home and fault), general purpose controller configured optically isolated I/O, and high speed, general purpose, differential receivers and transmitters for use as input captures and output compares. Initial configuration and tuning can be performed through an RS232 port using Glentek’s WindowsÔ based MotionMaestroÔ software or directly by the SynqNetÔ controller. These amplifiers include extensive fault detection with associated 7-segment display diagnostics.

SynqNetÔ is an all-digital motion control interface for connections between controllers and drives developed by Motion Engineering specifically for the motion control industry. The physical layer of SynqNetÔ is based on IEEE 802.3 standards for 100Base-TX, the physical layer of Ethernet. It supports up to 32 coordinated axes with update rates up to 48KHz (4 axes) and cable lengths up to 100 meters between nodes. Full SynqNetÔ compliant drives, such as Glentek’s Omega-SynqNetÔ drive, synchronize their control loop updates to the master SynqNetÔ drive strobe to minimizes control loop jitter and skew resulting in improved motion control. SynqNetÔ facilitates remote configuration, control and monitoring of drives and remote drive firmware updates. The network is electrically isolated for noise immunity and includes data path redundancy for fault tolerant operation. SynqNetÔ eliminates the traditional noise-prone ±10V analog signal, and relocates the encoder and I/O connections, which traditionally required routing through long cumbersome cables, to the drives. The only remaining connection required at the controller is an industry standard 100Base-Tx network cable. By locating the drives near the motors, the cabling can be kept short which aids in noise immunity, reduces EMI, and reduces cabling complexity and cost.

Features

· 100% SynqNetÔ compliant Allows complete drive configuration, control, monitoring and firmware updates over the SynqNetÔ network. Synchronizes to SynqNetÔ network update to minimize update jitter and skew for improved motion control.

· Digital current loops Current loop bandwidths up to 3 kHz.

· Digitally tuned All parameters set digitally. No potentiometers to adjust. DSP control for the ultimate in high performance.

· Silent operation 24 kHz PWM standard.

· Complete isolation Complete optical isolation between signal and power stage.

· Wide operating voltage 24-370 VDC for Amplifier modules. All stand-alone and multi-axis versions can be ordered for operation from either 110-130 VAC or 208-240 VAC (single or 3-phase, 50/60 Hz).

· Direct AC operation No transformer required for stand-alone units or multi-axis chassis. Most stand-alone units and all multi-axis chassis include a DC bus power supply, regen clamp with dumping resistor, in-rush current limiting protection at power-on and cooling fans. Note: A reduced cost stand-alone version is offered which does not include the regen circuit or cooling fans.
