Pc-Board DMRPP05
The pc-board DMRPP05 is the control unit for Push-Pull torches and the NanoFeeder.
In case of a Push-Pull application the DMRPP05 replaces the standard motor control pc-board DMR-RT3.
it consists of two pc-boards that are connected via at ribbon cables:
- pc-board DMRPP-P: power board containing the motor driver circuits
- pc-board DMRPP-C05: control logic
Functions
- driving and monitoring the normal wire feed motor as well as the Push-Pull motor
- driving the solenoid valve
- monitoring control elements (front panel, torch trigger switch)
