Input the
torque
reference
The servo
motor does not
rotate.
The internal
torque reference
(H0B-02) is 0.
•
The AI wiring is incorrect.
When the torque reference is input through
AI, check whether the AI is wired correctly by
referring to Chapter 3 Wiring of Servo System.
•
The torque reference selection is incorrect.
Check whether H07-02 (torque reference
source) is set correctly.
•
The torque reference is not input
When AI is selected to input the torque
reference, check whether the AI related
parameters in group H03 are set correctly rst.
Then check whether the input voltage is correct
by observing the voltage on oscilloscope or
viewing the AI sampling voltage in H0B-21 or
H0B-22.
When digital setting is used to set toque
reference, check whether H07-03 (keypad
setting value of torque reference) is 0.
When communication is used to set toque
reference, check whether H31-11 (torque
reference set via communication) is 0.
The servo
motor rotates
in the reverse
direction.
The internal
torque reference
(H0B-02) is
negative.
•
When AI is selected to input the torque
reference, check whether the polarity of input
signal is reversed. You can conrm the condition
by using an oscilloscope or viewing H0B-21 or
H0B-22.
•
When digital setting is used to set the speed
reference, check whether H07-03 (keypad
setting value of torque reference) is smaller than
0.
•
When communication is used to set toque
reference, check whether H31-11 (torque
reference set via communication) smaller than
0.
•
Check whether the DI function FunIN.25:
ToqDirSel (torque reference direction) has been
allocated and whether the logic of corresponding
DI is effective.
•
Check whether H02-02 is set correctly.
■ After the preceding causes are removed, the servo motor can rotate.
The servo
motor jitters at
low speed.
The motor
speed is not
steady.
The gain is set
unreasonably.
•
Perform automatic gain adjustment based on
section 4.5.2 Automatic Gain Adjustment.
The motor
shaft vibrates
left and right.
The load inertia
ratio (H08-15) is
too large.
•
If the servo motor can run safely, perform the
inertia auto-tuning based on section 4.5.1 Inertia
Auto-tuning
•
Perform automatic gain adjustment based on
section 4.5.2 Automatic Gain Adjustment.
