Electronic error codes HTC 650 and HTC 800 - Hitachi
An error code is automatically displayed if a fault causes the frequency converter to trip out.
The following list contains error codes and their possible causes. For resetting see page 45.
Error
code
Explanation Description of possible fault
E01 Overload under continuous operation. The most common codes in this category
are E01 and E03. This error may arise in the
event of momentary overload. This may be
due to the machine being run too quickly or
with a high load. Try reducing the speed, alle-
viating the load by moving the position of the
weights and checking your tools. If the error is
an E03, you can try starting the machine on
another surface.
E02 Overload under retardation. See E01
E03
Overload under acceleration. See E01
E04
Overload at stationary position. See E01
E05 Overload Occurs during prolonged overloads. If the
overload lamp has been lit for a length of
time, this will be the result when the electron-
ics cannot handle the load any more. Drop
the speed or reduce the load by adjusting the
weights or tools.
E07 Overvoltage May arise if there is a mechanical fault and
the motor generates current back to the elec-
tronics. Check the mechanical functionality
such as belts and bearings.
E08 EEPROM error Occurs rarely but may arise from high tem-
peratures in the electrical cabinet. Open the
cabinet and air out. Check filters and cooling
fans in the cabinet.
E09 Undervoltage Occurs if the voltage (volts) is too low. May
occur where there are long cables or poor
connections (contacts). May also arise if there
are many users in the network. Try chang-
ing outlets, shortening cables and reducing
speed.
E10 Current transformer interference Contact service if this is the case. The internal
transformer needs replacing.
