4. STARTUP
4 - 13
4.3.5 Actual operation
Start actual operation after confirmation of normal operation by test operation and completion of the
corresponding parameter settings.
4.3.6 Trouble at start-up
CAUTION
Never make a drastic adjustment or change to the parameter values as doing so
will make the operation unstable.
POINT
Using the optional MR Configurator2, you can refer to reason for rotation failure,
etc.
The following faults may occur at start-up. If any of such faults occurs, take the corresponding action.
No. Start-up

7-segment LED is
not lit.
7-segment LED
blinks.
Not improved even if CN1 and
CN2 connectors are
disconnected.
1. Power supply voltage fault
2. The servo amplifier is
malfunctioning.
Improved when CN1 connector is
disconnected.
Power supply of CN1 cabling is
shorted.
Improved when CN2 connector is
disconnected.
1. Power supply of encoder
cabling is shorted.
2. Encoder is malfunctioning.
Alarm occurs.
Refer to chapter 8 and remove cause.
Chapter 8
2
Switch on SON
(Servo-on).
Alarm occurs.
Refer to chapter 8 and remove cause.
Chapter 8
Servo motor shaft is
not servo-locked.
(Servo motor shaft is
free.)
1. Check the display to see if the
servo amplifier is ready to
operate.
2. Check the external I/O signal
indication (section 4.5.7) to
see if SON (Servo-on) is on.
1. SON (Servo-on) is not input.
(wiring mistake)
2. 24 V DC power is not supplied
to DICOM.
Section
4.5.7
3
Switch on ST1
(Forward rotation
start) or ST2
(Reverse rotation
start).
Servo motor does not
rotate.
Call the status display (section
4.5.3) and check the input
voltage of VC (Analog speed
command).
Analog speed command is 0 V.
Section
4.5.3
Call the external I/O signal
display (section 4.5.7) and check
the on/off status of the input
signal.
LSP, LSN, ST1, and ST2 are off.
Section
4.5.7
Check the internal speed
commands 1 to 7 ([Pr. PC05] to
[Pr. PC11]).
Set value is 0.
Section
5.2.3
Check the forward rotation
torque limit ([Pr. PA11]) and the
reverse rotation torque limit ([Pr.
PA12]).
Torque limit level is too low as
compared to the load torque.
Section
5.2.1
When TLA (Analog torque limit)
is usable, check the input voltage
on the status display.
Torque limit level is too low as
compared to the load torque.
