180 H7 ASD Operation Manual
E-13 Speed Error
(Over Speed)
This fault is the result of a
motor speed that is greater
than the commanded speed
when using an encoder for
speed control.
• Improper encoder
connection or setup
information.
• Defective encoder.
• Ensure that the encoder
connections are correct
and secured.
• Ensure that the PG
settings are correct for the
application (Program
⇒
Feedback Parameters
⇒
PG Settings).
• Replace the encoder.
E-17 Key Error This fault is caused by an
improper response from the
EOI.
• Defective EOI. • Replace the EOI.
E-1 or E2 Panel Overflow
Indicator (LED
display only)
This fault is displayed in the
event that the value shown
is comprised of more digits
than that which can be
displayed on the LED
display.
• The displayed number has
more characters than that
which will fit the LED
display.
EEP1 EEPROM Error This fault is caused by an
EEPROM write error.
• An EEPROM write error.
•Defective EEPROM.
• Reset the ASD and retry.
• Make a service call if the
failure persists.
EEP2 Initial Read Error This fault is caused by an
EEPROM read error.
• An EEPROM read error.
•Defective EEPROM.
•Defective EEPROM.
• Reset the ASD and retry.
• Make a service call if the
failure persists.
EEP3 Initial Read Error This fault is caused by
corrupted firmware or an
inability to read the
firmware.
• An EEPROM data error.
•Defective EEPROM.
• Reset the ASD and retry.
• Make a service call if the
failure persists.
EF1 or
EF2
Ground Fault Trip This fault occurs when the
amount of current that
enters the ASD at the R, S,
and T leads is different from
the current leaving on the
return line.
• Ground fault at the motor.
• Ground fault at the output
of the ASD.
• Current leakage to Earth
Ground.
• Ensure that the ground
connections are correct
and secured.
• Ensure that CC is not
connected to Earth
Ground.
• Disconnect the output of
the ASD from the motor
and meggar the motor.
EMG Emergency Off This code is displayed when
the ASD is stopped via the
EOFF command using
either the Stop|Reset key or
is input remotely.
• Stop|Reset key was pressed
twice at the EOI.
•The EOFF command was
received remotely.
• Reset the ASD.
EPH1 Input Line Loss This fault occurs when one
or more of the input power
lines to the ASD are
inactive or missing.
• Input power line is not
secured to the input terminal
of the ASD.
•An R, S, or T fuse is open
(blown).
• Ensure that the input
power lines are connected
securely and of the proper
voltage levels.
• Ensure that the input
