11
Error and Maintenance
25
Excessive hybrid
deviation error
Occurs for full closing
control.
• There is deviation
between the load
position according to
the external encoder
and the motor position
according to the
encoder.
• Check the motor and
load connection.
• Check the external
encoder and drive
connection.
• Check the external
encoder load position
and encoder motor
position settings.
26
Overspeed
Occurs during high-speed
rotation.
• The speed command
input is too large.
• Give a speed
command of 500 Kpps
or lower.
• The setting for the
Electronic Gear Ratio
Numerator (Pn009) is
not appropriate.
• Set the electronic gear
ratio in a way to give
the speed command of
500 Kpps or lower.
• The speed exceeds the
maximum rotation
speed 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.
• When the torque limit
switching function is
used, set the motor
operating speed range
correctly on the Error
Counter Overflow
Level (Pn014).
27
Command pulse error
Occurs during a trial
operation.
• The multi-turn counter
of the absolute
encoder was cleared
by the CX-Drive.
• Turn off the control
power, and turn it on
again.
• MECHATROLINK-II
communication is
established during CX-
Drive trial operation.
• Do not establish
MECHATROLINK-II
communications
during CX-Drive trial
operation.
Occurs when control
signal is input or
command is input.
• The speed command
exceeds the limit.
• Confirm the speed
command.
• The position command
variation during
interpolation and
others is too large.
• Confirm the position
command variation
volume.
• The setting for the
Electronic Gear Ratio
Numerator (Pn009) is
not appropriate.
• Set the electronic gear
ratio numerator so that the
command pulse frequency
is 500 Kpps max.
• Backlash
compensation amount
is too large.
• Reduce the backlash
compensation amount.
