speed.
Motor shaft vibrates
side to side.
Rotation inertia ratio
of load (Po013) is
too high.
If servo drive runs safely, please
recognize inertia again according to
chapter 7.3.
Adjust gain according chapter 7.
9.1.3 Torque control mode
Start-up process
Description
Cause
Countermeasures
Connect control
powe(L1C,L2C)
and main power
supply(R/L1 ,S/L
2, T/L3)
Digital tube is not on
or green light is not
on
1. Control
terminal is
disconnected
Rewire
Connect L1C/L2C power cable to
socket separately.
2.Control power
supply fault
Check the voltage between L1C and
L2C
Note: 380V servo drive doesn’t need
to connect to L1C and L2C.
3.Servo drive fault
Please contact with manufacturer.
Keypad panel
displays ’AL-XXX’.
Refer to chapter 9.2 to find the cause and solve the problem.
Servo drive
enabled signal is
valid
（
/S-ON is
ON
）
Kaypad panel
displays ’AL-XXX’.
Refer to chapter 9.2 to find the cause and solve the problem.
Servo motor is in
unlocked state.
1. Servo drive
enabled signal is
invalid
Check whether green light is on, if it is
not, take the following step.
Check whether Po004=0, if it is not,
set 0 to Po004, then repower on.
Check whether Lo-15.A is 1, if it is
not, check whether wiring is correct.
2.Control mode is
wrong
Check whether Po001.X is correct.
Input torque
command
Servo motor doesn’t
rotates or speed is
not correct.
1. Lo-13 has no
change.
2. Forward and
reverse running is
prohibited.
Analog interface wiring is wrong.
Check whether analog wiring is correct
when set command source by Po428,
referring to chapter 4.
No speed command is input.
1. Check whether DI function 2 (forward
torque limit) or DI function 3(reverse torque
limit) is used.
2. Check whether DI function 11 (common
pulse prohibited) is used.
3. Check whether Po429 is set correctly.
4.Check whether Po204 is zero when digital
command is given.
Servo motor is
galloping.
Encoder cable fault
1. Check whether Lo-04 value is correct
when motor rotates 1 revolution.
2. Check whether servo drive trips into
AL-17
U/V/W motor cable is wrong
