1.1 Description

The P1P51FC20 – 008 application, installed on the Qmove+ J1-P51-FC20 and Remote I/O modules RMC-2M, has been designed to control a marble slab polishing machine with mobile beam.

Salient Features of the control

Control of 2 axes in analog (beam + belt)
Control of up to 12 heads (depending on hardware)
Control of accessories (brush, sprays)
Slab sizing by Sensor bar
Touchscreen functions for data settings and actions by buttons
Staggered motor startup
Operator help messages
Alarm messages

Yellow settings can be modified. Press to change, use the keypad to enter a setting.
Select multiple choice parameters.

Parameter	Unit Measure	Range	Description
Front correction (on left)	mm	-9999.9 - 9999.9	Advance space (positive) or delay (negative)of head operation on front of piece
Back correction (on right)	mm	-9999.9 - 9999.9	Advance space (positive) or delay (negative) of head stop on end of piece
Reference speed	mm/s	0 - 99999.9	Speed used as reference for the corrections. Proportional correction varies with the speed change. Setting = 0 Constant correction at any speed

Parameter	Unit Measure	Range	Description
IN correction (above)	mm	-9999.9 - 9999.9	Advance (positive) or delay (negative) the head start on the front edge of the slab

Cancel alarms and restore machine operation
If alarm repeats, a new message is given - If there is no alarm, the Main screen is opened.

Id	Message	Cause	Remedy
1	Air pressure	No air pressure or pressure switch fault (I17 off)	Check pressure switch and cabling
2	Thermal overload	A cutout has tripped (I161)	Check the cutouts and cables
3	Beam Inverter fault	Beam inverter fault (I13 off)	Check the inverter and cables
5	Belt Inverter fault	Belt inverter fault (I15 off)	Check the inverter and cables
6	Emergency pressed	Emergency button pressed (I01 off)	Release the emergency button and check the cables
7	No Abrasive	Abrasive worn out and needs changing	Check head abrasive levels
8	CANBUS comunication error (node 1)	CANopen comm error at node 1 = RMC2M cabinet	Switch the system Off - On. Check the cables
9	CANBUS comunication error (node 2)	CANopen comm error at node 2 = RMC2M beam	Switch the system Off - On. Check the cables
11	One head distance over maximum length	A Head distance is too long for the linear step Only during automatic	Check the head distances Increase the linear step (general setup)
12	Belt encoder fault	No Belt encoder pulses received	Check the encoder, the axis movement, the cables
