SYNTEC 6MB password is 520

1.change parameter :
884—0
3420–1024
Note :parameter 3420 is 0 or 1024
0 means cant change tools manually
1024 means can change tool changers manually

2.Tool changers back Home .
Button Home ,then button CYCLE START

3.JOG mode ,button CCW make tool changers to the left

4.Button MPG ,use the hand wheel .

Carefully use hand wheel ,make tools in right position .
Then write down the coordinate

Then change the parameter below :
2803 Z
2801 X
2802 Z +20
884 A

5.Button RESET on the right .

BACK HOME
6.3420 change to 0 ,make sure other people cant change tools changers position .

Try to set the f.07 parameter in the invert(frequency 300=18000RPM),calculate the right frequency equal to the RPM(accurate to percentile),then set the new parameter into it . 

Anyway,Do not change the invert settings usually,because we had settled well before leave our factory.

Put a MDF board on the table, control the machine to drill 4 holes at 4 corners of  rectangular(it is according to your machine size, if it is 1530 then drill the holes at 1500X3000mm area), measure its diagonal length, then you will find one diagonal longer than the other, loose the longer side linear block screws (8pcs), remove the other side motor plug(so it will not move), and move the longer side a little forward until the gantry is totally vertical to the Y axis of the machine, then fix all the linear block screws again.

After you adjust the Y axis linear blocks, you can drill 4 holes on the machine 4 corners then measure if the diagonal length to be the same or not, if not the same, then need to adjust again according to which side is shorter or longer.

1.Run the machine and  make machine home .

2.Use hand wheel moving the machine to the center of tool sensor

3.write down XY coordinate

4.To the parameter 3415 write X coordinate

3417 change to Y coordinate .

Only three buttons are operator accessible,ARROW UP, ARROW DOWN and STOP KEY.ARROW UP button is used to raise the spindle speed.


ARROW DOWN button is used to lower the spindle speed.
Note: Do not set the hertz lower than 100, as this will labor the motor and could cause motor failure.The stop key is available to stop spindle during a
program activation.
Note: It is strongly recommended that the stop button is not used and the spindle is stopped using the hand held controller.
Display reads in hertz, 200hz = 12,000RPM, 300hz= 18,000RPM, 400hz = 24,000RPM.
Note: 1hz = 60 RPM.

Machine will not start
1. Check that the start switch is being pressed full in.
2. Check that the red emergency stop switch is fully out.
3. Check that the electrical power cord is plugged into the power outlet.
4. Check that the electrical supply is on (reset the breaker).
5. With the power disconnected from the machine, check that the wiring to the plug is
correct. Check that the rubber insulation is stripped enough and is not causing a bad
connection. Check that all the screws are tight.
The machine will not stop
This is a very rare occurrence, as the machine is designed to fail-safe. If it should
occur and you cannot fix the fault, seek professional assistance. The machine must
be disconnected from the power and never run until the fault has been rectified.
1. Internal breaker faulty. Replace the breaker.
Motor tries to start but will not turn
1. With the power disconnected from the machine, try to turn the spindle by hand. If
the spindle will not turn, check the reason for the jamming.
2. Motor faulty. Replace the spindle.
3. Spindle run without coolant. Replace the motor.
4. Check that the voltage supplied to the VFD is 220V.
Motor overheats
Typical reasons are dull cutting tools, no water in the coolant tank, blockage in the
coolant pipe and excessive ambient temperature.
Squeaking noise
1. Check the bearings.
Spindle slows down during a cut
1. Dull cutting tools. Replace the tool or have it re-sharpened.
2. Feeding the wood too fast. Slow down the feed rate.
3. Cutter feeds and spindle speed are not correct. Adjust the feeds and speeds.
Fuses
Note: Never access the inside if the electrical box with the mains is connected.
The electrical functions of the machine are protected by fuses.To access the fuse, pull the fuse holder up.Once the fuse has been checked that it has not blown, ensure that the fuse
holder is pushed down and is fully home.
Troubleshooting Machine vibrates
1. Machine not level on the bench. Re-level the machine, ensuring that it has no movement.
Machine will not home
1. Are the home position sensors connected, damaged or out of adjustment?
2. Are the parameters in the hand held controller correct?
3. After completing the job, press OK button and check if the router head returns to
the home position.
Jobs are machined inconsistently
1. Check that the motor drive belt is tight and not damaged. If damaged, replace.
2. Check if the drive couplings are tight or damaged. If loose, tighten; if damaged,replace.
3. Check if the slider bearings are fixed tight or damaged. If loose, tighten; if damaged, replace.
Inaccurate position of router head
1. Check that the drive screws and the bearing rails are clean and lubricated.
2. If the gantry/router head movement is too fast:
2.1 Check that the parameters are set correctly in the hand held controller.
2.2 Check for static or external electrical interference and the machine is correctly earthed.
2.3 Check that all the bearing, motor-fixing bolts are tight.
2.4 Check the input voltage is correct; it must be 220V.
The hand held controller screen is blank or dull or flickers
1. Check that the cable to the hand held controller is fitted correctly and the clamping screws are tight.
2. Check that the connectors on the interface printed circuit board are fitted correctly and that all the screws are tight.
3. Check if a fuse has blown.
4. The 50-pin interface is damaged. Replace the damaged part.
5. The power supply is damaged. Replace the power supply.
6. The hand held controller is damaged. Replace the hand held controller.
7. The supply voltage is not within specification.
The gantry or router head will not function
1. Hand held controller cable loose.
2. Drive wires loose or damaged.
3. Hand held controller damaged.
4. Drive circuit board damaged. Replace drive circuit board.

The cutting depth is inconsistent
1. Check that the spoil boards are flat and clean prior to fitting the job.
2. Check if there is excessive play in the Z axis ball screw drive mechanism.
3. Check that the bit is tight in the spindle collet.
The hand held controller display shows that the spindle is on but the spindle is
not rotating, and vice versa
1. Check the wiring for loose or broken wires.
2. The spindle settings on the HHC are incorrect.
