1、The XYZ4 four-way motor control signal on the board uses the transistor OC output. The drive capacity reaches 200MA. One port can simultaneously connect 10 motor drives or drive 4 relays at the same time, which has a large driving capacity. 2、The output and input signal numbers are processed by special high-speed chip, the signal is corrected, amplified, and unnecessary interference signals are removed, so that the whole machine runs more stably. 3、The LPT port power supply of the computer is isolated from the power supply of other parts, so that the computer and the machine tool can be effectively isolated. This further guarantees safety and stability. Make computers and machined data safer 4、There are 5 input signals communicating with the host computer, all of which are isolated by optical diaphragm. P11 and P12 port are high-speed diaphragm isolation, which can be used to connect the spindle code disc, or the hand wheel A and B are equally 5、A total of 12 output signals are available. It can support 6 linkage control output. It is also possible to select only one or several of these axes to control.
