Error and Maintenance
26 Overspeed
Occurs during high-speed
rotation.
• The speed command
input is too large.
• Set the command pulse
frequency to 500 Kpps max.
• The setting for the Electronic
Gear Ratio Numerator
(Pn009, Pn500 to Pn502) is
not appropriate.
• Set the electronic gear
ratio numerator so that the
command pulse frequency
is 500 Kpps max.
• The maximum rotation
speed is exceeded due
to overshooting.
• Adjust the gain.
• Reduce the maximum
command speed.
• The encoder is wired
incorrectly.
• Wire correctly.
Occurs when torque limit
switching function is used.
• The set value for the
Overspeed Detection
Level setting (Pn513)
is exceeded.
• If torque limit switching
function is used, correctly
set the allowable operating
speed for Pn014.
27 Command pulse error
Occurs when control
signal is input or
command is input.
• The command pulse
input frequency
exceeded the limit.
• Check the command
pulse input.
• Increase the set value
of Pn532.
• The setting for the Electronic
Gear Ratio Numerator
(Pn009, Pn500 to Pn502) is
not appropriate.
• Set the electronic gear
ratio numerator so that the
command pulse frequency
is 500 Kpps max.
28
Pulse regeneration
error
Occurs during operation.
• The pulse regeneration
output frequency
exceeded the limit.
• Check the set value of
Pn011 and Pn503.
• Set Pn533 to 0 to
disable the function.
29 Error counter overflow Occurs during operation.
• The error counter value
for the encoder pulse
reference exceeded
2
29
(536,870,912).
• Check that the motor
rotates according to
the position command.
• Check on the torque
monitor that the output
torque is not saturated.
• Adjust the gain.
• Increase the setting for
Pn013 or Pn524 to the
maximum.
• Wire the encoder correctly.
30 Safety input error Occurs during operation.
• Safety input signal
turned OFF.
• Check the statuses of
safety inputs 1 and 2.
33
Interface I/O allocation
error Occurs when the power
supply is turned ON.
• There is a duplicate
setting in the I/O signal
function allocation.
• Specify the undefined
number with the I/O
signal function allocation.
• Set the function
allocation correctly.
• There is a mistake in the
counter function allocation.
• Allocate to SI7.
• There is a mistake in the
command pulse prohibition
input function allocation. • Allocate to SI10.
