January 29, 2012 - Servo2Go.com introduces SVAC3 Series Digital Servo Drives. The SVAC3 is a powerful servo controller in a compact and cost effective package. This AC powered drive is loaded with features and options that make it a great choice for many OEM applications. SVAC3 drives can be controlled via analog signal or step and direction inputs. Alternatively, they can be programmed to act as stand-alone units with the power of Q Programmer.
All models include EtherNet/IP industry-standard network communication which simplifies connection to the supplied Windows PC software for configuration and tuning, and allows applications to communicate in real time using the SCL and Q languages over standard 100Mbit Ethernet cabling, addressing and protocols.
The SVAC3 also provides an upgrade path for users who want to migrate from step motors to servo motors without a large cost increase. Paired with a V or M series servo motor, the SVAC3 servo drive offers great value.
Three drive models are available, each in 120VAC and 220VAC versions. The 120V versions provide up to 3.5 A rms continuous current and 7.5 A rms peak. The 220V versions provide up to 1.8 A rms continuous and 5.4 A rms peak. A built-in regeneration (power dump) circuit safely disperses incoming energy from rapidly decelerating inertial loads.
There are 3 control options available with the SVAC3 servo drives: S, Q and IP.
- “S” drives can operate in analog torque/velocity, pulse & direction, and streaming serial (SCL) control modes. Select the control mode, tune the servo motor and configure the drive using the Quick Tuner software
- “Q” drives can operate in all of the same control modes as S drives, plus they have the ability to run stand-alone Q programs stored in non-volatile memory. Q program are created using the Q Programmer software, and provide multi-tasking, math functions, conditional processing, data register manipulation, and more features in a robust yet simple text-based programming language. Like S drives, Q drives must first be set up and tuned using the Quick Tuner software
- “IP” drives come with built-in EtherNet/IP network communications, the widely used industrial protocol for manufacturing automation applications. With EtherNet/IP, users can control, configure and query the drive using an open, standards-based, industrial Ethernet connection at speeds up to 100 Mbits/sec. The SVAC3-IP drives run all of the same control modes as Q drives, with the addition that all drive features can be accessed over EtherNet/IP, including more than 100 commands and 130 registers for controlling motion, I/O, configuration, polling, math, register manipulation, and Q programming. SVAC3-IP drives are set up and configured using Quick Tuner, while Q programs are created using Q Programmer
