Connect the
control power
L1C/ L2C
and main
power RST.
The LED
display is not
on or does not
display Rdy.
1. The control
power voltage is
abnormal.
•
After disconnecting CN1, CN2, CN3 and CN4,
the fault remains.
•
Measure the AC voltage between L1C and
L2C.
2. The program
burning terminal
is shorted.
•
Check whether the program burning terminal is
shorted.
3. The servo
drive is faulty.
-
The operation
panel displays

signal (S-ON)
to ON.
The operation
panel displays
"Er.xxx".
Refer to section 6.2 to eliminate the fault.
The shaft of
the servo motor
is in the free
running state.
1. The servo
enabled signal is
ineffective.
•
Switch over the operation panel to the display
of servo state and view whether the operation
panel displays "Rdy" rather than "Run".
•
Check whether any parameter in groups H03
and H17 is allocated with the DI function
1 FunIN1: S-ON (servo enabled). If yes,
check whether the corresponding DI is set to
ON. If not, allocate the function and set the
corresponding DI to ON.
•
If a parameter in group H03 has been allocated
with the FunIN1: S-ON function and the
corresponding DI is ON, but the operation
panel still displays "Rdy". In this case, check
whether the DI terminal is connected correctly
by referring Chapter 3 Wiring of Servo System.
2. Control
mode selection
incorrect
•
Check whether H02-00 is 0. If it is set to 2
(torque mode), the motor shaft must be in the
free running state because the default torque
reference is 0.
■ After the preceding causes are removed, the operation panel should display "Run".
