The power LED
indicator (PWR)
does not light
when the power
supply is turned
ON.
The Servomotor
does not rotate
even if
commands are
input from the
Controller.
(Continued on
next page.)
Symptom
The power supply cable is
wired incorrectly.
The RUN Command Input
is OFF.
The Forward Drive Prohibit
Input (POT) and Reverse
Drive Prohibit Input (NOT)
are OFF.
The control mode is not
correct.
The Deviation Counter
Reset Input (ECRST) is
ON.
The Command Pulse Mode
(Pn42) is incorrect.
The Zero Speed Designa-
tion Input (VZERO) is OFF.
The internally set speeds
are not set.
No. 1 Torque Limit (Pn5E)
or No. 2 Torque Limit
(Pn5F) is set to 0.
The Servomotor Power
Cable is wired incorrectly.
The Encoder Cable is wired
incorrectly.
The Control I/O Connector
CN1) is wired incorrectly.
The power supply is not
ON.
The speed command is
disabled.
Probable cause
Check whether the power supply
input is within the allowed voltage
range.
Check whether the power supply
input is wired correctly.
In monitor mode, check whether the
RUN signal is ON or OFF.
In monitor mode, check whether the
POT input and NOT input are ON or
OFF.
Check the Control Mode Selection
(Pn02).
In monitor mode, check whether the
ECRST Input is ON or OFF.
Check the Controller’s command
pulse type and the Servo Drive’s
command pulse type.
In monitor mode, check whether the
VZERO Input is ON or OFF.
Check the settings for Pn53 to
Pn56 or Pn74 to Pn77.
Check the setting for Pn5E or
Pn5F.
Check the wiring.
Check the command pulse’s wiring. Correct the wiring.
Check the command pulse type.
Check the command pulse’s
voltage.
Check whether the power supply is
ON and check the PWR LED
indicator.
Check the voltage across the power
supply terminals.
Check if the speed command
procedure is correct.
Items to check
Supply the correct voltage.
Correct the wiring.
Set the control mode to
match the command type.
Set the Servo Drive’s pulse
type to match the Control-
ler’s command pulse type.
Set the desired speeds.
Return the setting to the
default.
Correct the wiring.
Set the Servo Drive’s pulse
type to match the Control-
ler’s command pulse type.
Connect a resistor that
matches the voltage.
Turn ON the power supply.
Wire the power supply’s ON
circuit correctly.
• Turn ON the RUN
• Correct the wiring.
• Turn ON the POT and
• If the POT and NOT
• Turn the ECRST Input
• Correct the wiring.
• Turn ON the VZERO
• Correct the wiring.
• Correctly set the external
