Quick Reference is a summary for the experienced users.
Figure 1 is a shrinkage view of MB3 board. It shows the connection of inputs & outputs, power supply,
analog output for the VFD and axis signals.
Table 1 is a summary of Ports and Pins and their corresponding reference numbers. All pin numbers
preceded by an “X” are inputs and if preceded by a “Y” are outputs. Using X110 as an example. The
“X” means it is an input. The first digit “1” is the port number, the last 2 digits “10” is the pin number.
