Check result
Action
6A MC drive circuit
error
Failure of the
magnetic
contactor drive
circuit
The main circuit
power supply is
still on even when
the magnetic
contactor output
was turned off.
(1) The setting value of the
rotary switch for
magnetic contactor
drive output contradicts
the wiring constitution.
Check the setting of
the rotary switch and
the wiring constitution.
The setting or wiring
constitution is
incorrect.
Check the setting of
the rotary switch or
wiring constitution.
The setting and
wiring constitution
are correct.
Check (2).
(2) The magnetic contactor
failed.
Replace the magnetic
contactor, and then
check the
repeatability.
It is not repeatable.
Replace the
magnetic contactor.
It is repeatable.
Check (3).
(3) A part in the power
regeneration converter
unit is malfunctioning.
Replace the power
regeneration converter
unit, and then check
the repeatability.
It is not repeatable.
Replace the power
regeneration
converter unit.
6B Inrush
current
suppression circuit
error
The inrush current
suppression
circuit error was
detected.
(1) The inrush relay was
turned on and off very
frequently.
Check if the inrush
relay is turned on and
off very frequently.
It is turned off and
on.
Check operation
pattern.
It is not turned off
and on.
Check (2).
(2)
Inrush
current
suppressor circuit is
malfunctioning.
Replace the power
regeneration converter
unit, and then check
the repeatability.
It is not repeatable.
Replace the power
regeneration
converter unit.
6C Main circuit error
An error was
detected when
the main circuit
capacitor was
being charged.
(1) The total capacity of
connected servo
amplifiers other than
multiple drive units
exceeds the
permissible capacity of
servo amplifiers
connected to the power
regeneration converter
unit.
Check if the total
capacity of connected
servo amplifiers other
than multiple drive
units is within that of
servo amplifiers
connectable to the
power regeneration
converter unit.
It exceeds the total
capacity of servo
amplifiers
connectable to the
power regeneration
converter unit.
Review the
capacity.
It is less than or
equal to the total
capacity of servo
amplifiers
connectable to the
power regeneration
converter unit.
Check (2).
(2) A part in the power
regeneration converter
unit is malfunctioning.
Replace the power
regeneration converter
unit, and then check
the repeatability.
It is not repeatable.
Replace the power
regeneration
converter unit.
It is repeatable.
Check (3).
(3) The servo amplifier is
malfunctioning.
Replace the servo
amplifier, and then
check the
repeatability.
It is not repeatable.
Replace the servo
amplifier.
6E Board
error
A part in the
power
regeneration
converter unit is
malfunctioning.
(1) A part in the power
regeneration converter
unit is malfunctioning.
Disconnect the cables
except for the control
circuit power supply,
and then check the
repeatability.
It is repeatable.
Replace the power
regeneration
converter unit.
It is not repeatable.
Check (2).
(2) Something near the
device caused it.
Check the power
supply for noise.
There is a problem. Take
countermeasures
against its cause.
70 Converter
forced
stop error
EM1 (Forced
stop) of the power
regeneration
converter unit
was turned off.
(1) EM1 (Forced stop) of
the power regeneration
converter unit was
turned off.
Check the status of
EM1 (Forced stop) of
the power
regeneration converter
unit.
It is off.
Ensure safety and
turn on EM1 (Forced
stop).
It is on.
Check (2).
(2) The external 24 V DC
power supply is off.
Check if the external
24 V DC power supply
is inputted.
It is not inputted.
Input the 24 V DC
power supply.
It is inputted.
Check (3).
(3)
The
power
regeneration converter
unit is malfunctioning.
Replace the power
regeneration converter
unit, and then check
the repeatability.
It is not repeatable.
Replace the power
regeneration
converter unit.
