Symptom
Probable cause
Check items
Measures
The PWR indicator
does not light
when the Servo
Drive is powered
on.
The power supply wiring is
incorrect.
Check to see if the power supply input
is within the allowed power supply
voltage range.
Supply the correct power
supply voltage.
Check to see if the power supply input
is wired correctly.
Wire correctly.
The Servomotor
does not rotate
when a command
is input from the
controller.
The Operation Command
(RUN) signal is OFF.
Check in the monitor mode if the RUN
signal turns ON/OFF.
• Input the Operation
Command (RUN) signal.
• Wire correctly.
Forward Drive Prohibition
Input (POT) or Reverse
Drive Prohibition Input
(NOT) signal is OFF.
Check in the monitor mode if the POT
and NOT signals turn ON/OFF.
• Turn ON the POT or NOT signal.
• Disable the parameter if the
POT or NOT signal is not used.
The control mode does not
conform to the command.
Check the value set in Control Mode
Selection (Pn001).
Set the control mode according
to the command.
The Error Counter Reset
Input (ECRST) signal is ON.
Check in the monitor mode if the
ECRST signal turns ON/OFF.
• Turn OFF the ECRST signal.
• Wire correctly.
The value set in Command
Pulse Mode Selection
(Pn007) is incorrect.
Check the command pulse type of the
controller and that of the Servo Drive.
Set the command pulse type of
the Servo Drive so that it
matches the command pulse
type of the controller.
The Zero Speed
Designation Input (VZERO)
signal is OFF.
Check in the monitor mode if the
VZERO signal turns ON/OFF.
• Turn ON the VZERO signal.
• Wire correctly.
No internally set speeds are
set.
Check the values set in Pn304 to
Pn311.
Set the desired rotation speed.
The values set in No.1 Torque
Limit (Pn013) and No.2
Torque Limit (Pn522) are 0.
Check the values set in Pn013 and
Pn522.
Restore the default set values.
The Servomotor power
cable is wired incorrectly.
Check the wiring.
Wire correctly.
The encoder cable is wired
incorrectly.
The control I/O connector
(CN1) is wired incorrectly.
Check the command pulse wiring.
Wire correctly.
Check the command pulse type.
Set the command pulse type of
the Servo Drive so that it
matches the command pulse
type of the controller.
Check the command pulse voltage.
Connect resistors appropriate
for the voltage.
Power is not supplied.
Check the power supply and the PWR
indicator.
Turn ON the power supply.
Check the voltage across the power
terminals.
Wire the power-on circuit
correctly.
The speed command is
disabled.
Check to see if the speed command
input method is correct.
• Set the internal speed
correctly.
The torque command is
disabled.
Check to see if the torque command
input method is correct.
Set the torque command
correctly.
Both the CW and CCW
inputs are turned ON
simultaneously.
Check the command pulse wiring.
• Input the pulse signal to
either the CW or CCW input.
• Unused input terminals must
be always OFF.
The Servo Drive is faulty.
–
Replace the Servo Drive.
