MB2 ESS ethernet smooth stepper BOB breakout out board [MB2]
MB2 is a breakout board (BOB) for Ethernet SmoothSteppers (ESS). MB2 v1.5 continues to improve on functionality and components over its predecessor. MB2 is an industrial environment BOB, provides more convenient to make a connection, more robust to the noise and more features.
Specification and Features:
- With ESS, Ethernet connection helps controller and drives located away from PC and has more noise resistant than USB and parallel port connection.
- Run on Mach3 / Mach4 with Windows XP, Win7, Win8 both 32 and 64 bit, on both desktop and notebook computers.
- New! Utilizes All 3 ports of ESS.
- New! Motion command signal can be selected between Pulse/Sign, CW/CCW, Quadrature. Frequency can be selected from 32 KHz to 4 MHz.
- New! Differential line driver for motion signals, makes a longer wiring with more resistant to interference when comparing to TTL open end.
- New! Single 24Vdc Power supply is needed. On the board consist of 5Vdc isolate and non-isolate dc2dc converter, thus saving installation space and wiring.
- New! OSSD outputs and safety circuit are implemented. When a peripheral device such as servo motor drive and/or spindle VFD causes alarm. Safety Circuit will disengage OSSD output. This method is used in big CNC machine to cut power out off the drives.
- New! LED status for each input and output point including motion control signals. Makes it easy to diagnose the problem.
- Isolated power and ground between PC, ESS, I/O, which eliminates crossover noise and ground loop problem.
- New! Polarity and over voltage protection (in conjunction with fuse) for 24Vdc power supply.
- AnaSpeed circuit is implemented - the circuit is isolated from MB2 itself, But be a part of VFD inverter and acts as a digital VR. High voltage noise of inverter can not interfere through this connection.
- A charge-pump signal is provided. This helps users to form a safety interlock condition among controller and devices.
- 22 isolated input points, consist of 17 points of NPN and 5 points of PNP type.
- 14 NPN isolated output points, sinks current up to 100mA for each channel (up to 500 mA per group, no short circuit protection).
- 2 relay, with both NO, NC contact.
- v1.5, Adding off delay time to on board relays for applications where off delay time are needed.
- Spring terminal for quicker connecting and disconnecting cable and resists to vibration. No more screws loose and tightening forgotten.
