The 7I95 is a Ethernet connected motion control interface designed for controlling up to 6 Axis of step&dir step motor or servo motor drives and includes encoder feedback for each axis. Step rates up to 10 MHz are supported. The 7I95 also has 24 isolated inputs plus 6 isolated outputs for general purpose I/O use. 6 high speed encoder interfaces are provided axis feedback and for spindle synchronized motion. Two RS-422/RS485 serial expansion ports and a parallel expansion port are also provided.
All step and direction outputs are buffered 5V signals that can drive 24 mA. All outputs support differential mode to reduce susceptibility to noise. The encoders can be used with TTL or differential input.
24 isolated inputs are provided for general control use including limit switch and control panel inputs. Inputs operate with 3V to 36V DC and can have a positive or negative common for sourcing or sinking input applications. 8 inputs can be used to support up to 4 quadrature MPGs. Six 36V 2A isolated outputs allow sinking, sourcing combinations of both.
Two RS-422/RS-485 interface is provided for I/O expansion via a serial I/O daughtercard. In addition to the on card I/O, A FPGA expansion connector compatible with Mesa’s 25 pin daughtercards or standard parallel port breakout boards allow almost unlimited I/O options including additional quadrature or absolute encoder inputs, step/dir or PWM/dir outputs, and field I/O expansion to hundreds of I/O points. All field wiring is terminated in pluggable 3.5 mm screw terminal blocks. The 7i95 runs from a single 5V supply
