Problem Likely cause Items to check Countermeasures
Check whether the power
supply input is within the
allowed voltage range. Supply the correct power. The power supply cable is
wired incorrectly.
Check whether the power
supply input is wired correctly. Wire correctly.
The power indicator
(PWR) does not light
when the power supply
is turned ON.
The external Regeneration
Resistance Unit is wired
incorrectly. Check whether the external
Regeneration Resistance Unit’s
cable is wired correctly. Replace the Servo Driver and
external Regeneration Resistance
Unit and wire them correctly.
The Run command (RUN)
is OFF. Check whether the REF
Indicator is lit green. If the REF Indicator is orange:
•
Input the Run command (RUN).
•
Wire the input correctly.
Check whether the REF
Indicator is flashing. If the REF Indicator is flashing:
•
Wire the input correctly.
•
Set the Servo Driver’s pulse type
to match the Controller’s
command pulse type.
The command pulse
setting is incorrect.
Check the Controller’s
command pulse type and the
Servo Driver’s command pulse
type. Set the Servo Driver’s pulse type to
match the Controller’s command
pulse type.
The Servomotor Power
Cable is wired incorrectly.
The Encoder Cable is
wired incorrectly.
Check the wiring. Wire correctly.
Check the command pulse’s
wiring. Wire correctly.
Check the command pulse type. Set the Servo Driver’s pulse type to
match the Controller’s command
pulse type.
The Control I/O Connector
(CN1) is wired incorrectly.
Check the command pulse’s
voltage. Connect a resistor that matches the
voltage.
Check whether the power
supply is ON and check the
PWR Indicator.
Turn ON the power supply. The power supply is not
ON.
Check the voltage across the
power supply terminals. Set up the power supply’s ON circuit
correctly.
The CW input and CCW
input are ON at the same
time.
Check the command pulse’s
wiring.
•
Input either the CW input or CCW
input to the pulse signal.
•
Always turn OFF the terminal that
is not being input.
Servomotor will not
rotate even though
command pulses are
being input from the
Controller.
Servo Driver is faulty. --- Replace the Servo Driver.
The Servomotor
operates momentarily,
but then it does not
operate.
The Servomotor Power
Cable or Encoder Cable is
wired incorrectly.
Check the wiring of the
Servomotor Power Cable’s U, V,
and W phases and check the
Encoder Cable’s wiring.
Wire correctly.
Check the command pulse type. Set the correct command pulse
input. The command pulse input
is incorrect.
Check the command pulse’s
voltage. Connect a resistor that matches the
voltage.
The Servomotor rotates
without a command.
Servo Driver is faulty. --- Replace the Servo Driver.
The Servomotor rotates
in the opposite direction
from the command. The CW input and CCW
input connections are
reversed. Check the Controller’s
command pulse type and the
Servo Driver’s command pulse
type.
Connect the CW pulse signal to the
CW input and the CCW pulse signal
to the CCW input.
