Where are you located? I may be able to recommend a technician. Otherwise, check the three phase voltage into the motor amplifier, it should be no less than 200 voltss on all three phases. If ok, remove the drive motor and check that the pan roller turns free. The problem could be with a...

What model press is it? L40 or L26/28

Another possibility is that there is insufficient voltage at the ink keys. If your press uses the little driver circuit boards mounted on the cover over the ink keys, check the voltage on the two large wires on all units. You should have a minimum of 12 volts on this line. The first unit...

If the main power is interupted, the main motor brake should come on. Does the press go into "Slow" speed which would light the lamp on the "slow" button or does the "fast" lamp stay on? I would check the belt tension on the main motor if the "Fast" lamp is still on when the press is slowing...

It sounds like you have a problem either with the invertor or the encoder on the main motor. These problems can be very difficult to diagnose without trying new parts. About all I can advise you is to check the incoming 3 phase voltage. If it is below 210, that could be a problem. Otherwise...

These are very good suggestions. Also, to prevent stray voltages from getting into the electronics, Komori specifies a "Y" distribution feed through a delta-wye electrostatically shielded transformer. The transformer has taps to adjust the press voltage which should be 220 volts +/- 5%. Anything...
