Status correction:
•
First it is necessary to establish if the error is in the pulse generation or on the main drive. You
can check it as follows:
- Press the "START" button/indicator again to quit the error, if the error persists, it will appear
again.
- If the laminating roll turned by approximately 1 in. (1 cm), the error is on the pulse
generation.
- If the laminating roll did not turn at all, there is an error in the main drive function.
•
Correction of the error in the pulse generation:
- The error is possibly caused by disconnection of conductors 601, 602 (phase A, phase B of
the IRC encoder) or 217, 215 (24 Vdc, 0V supply to the IRC encoder). Repair. See DA-41-
100n, sheet 6.
- Defective IRC encoder. Replace it.
- Defective rapid inputs X0, X1 on PLC of the machine control system. Replace.
•
Correction of the errors in the main drive function:
- The error may be caused by disconnection of conductor 906, which controls frequency
inverter U1. Repair it. See DA-41-100n, sheet 9
- Frequency inverter U1 failed. Reset the error by the control unit or by switching the machine
off and on. More detail about the frequency inverter - see the Mitsubishi manual.
- Frequency inverter U1 is defective. Replace it.
- Motor M1 is defective. Replace it.
- The error may be caused by disconnection of conductors 309, 310, 311 – interconnection
between frequency inverter U1 and motor M1. Repair. See DA-41-100n, sheet 3.
- The error may be caused by disconnection of conductors 307, 308, N – power supply to the
frequency inverter. Repair. See DA-41-100n, sheet 3.
