IS220PDIH1BD Data Communication Module

IS220PDIH1BD realizes data communication with the touch screen through RS232 port, and displays relevant data as well as help information and sets relevant data through the touch screen. For example, the distance of each feed of the machine head is actually and finally converted into the number of pulses output from the PLC, which ultimately controls the number of feed steps of the stepper motor. For example, when the transmission ratio of 1:30, screw pitch of 6mm, stepper motor 200 steps / turn, the stepper motor set the number of steps (n) and the head of the relationship between the actual amount of feed: n/200 × 1/30 × 6 = 0.1mm, that is, the stepper motor every 100 steps of the head of the feed for 0.1mm.

IS220PDIH1BD is the location address of the PLC, can be set through the touch screen, set the appropriate touch screen value input parameters of the decimal point position, that is, you can change the value of 10n or 101/n times. Setting the input value of 0.1mm on the touch screen, the corresponding PLC input value is 100, and the PLC will output 100 pulses through the specified channel, thus controlling the stepping motor to run for 100 steps.
