Troubleshooting Diagnosis (for Models with 200V AC Servomotor Equipped)

If a problem occurs, check the following points first in order to ensure quick recovery and prevent recurrence of the problem.

Check in status LED (SV/ALM LED)

○: Light ON, ×: Light OFF, ★: Blinking

SV/ALM LED (Right side as seen from the motor side)		Operation status		ALM signal (1) output status
SV (green)	ALM (red)	Operation status		ALM signal (1) output status
×	×	Control power OFF		OFF
×	×	Servo OFF		ON
×	○	Alarm generated		OFF
×	○	Stop switch ON (When using teaching pendant)		ON
○	×	Control Power ON, Servo ON		ON
★(*2) (Blinking in green, 500 ms, 1 Hz frequency)	×	Maintenance warning generated (When the travel count or the travel distance has exceeded the set value, or when overload warning is generated)		ON
★(*2) (Blinking in green, 1000 ms, 0.5 Hz frequency)	×	In process of automatic servo OFF		ON
○ (both green and red ON)			Initializing when power comes ON	OFF

*1 *ALM Signal is a signal of the break contact output.
*2 Pay attention to blinking frequency as it is different for the maintenance warning and automatic servo OFF.

Right side as seen from the motor side

Check in status LED (Motor power supply status LED)

○: Light ON, ×: Light OFF, ★: Blinking

Motor Power Supply Status LED (In the middle in the view from motor side)		Motor power supply status
Green	Red	Motor power supply status
○	×	Motor power turned ON
★	×	Motor power turned OFF
○	○	Initializing when power comes ON

In the middle in the view from motor side

Check in status LED (Wireless status LED)

○: Light ON, ×: Light OFF, ★: Blinking

Wireless status LED (Left side as seen from the motor side)		Operation status
Green	Red	Operation status
×	×	Wireless not connected (transmitting monitor data) Connecting from wired teaching pendant
×	★ (ON 200ms/OFF 200ms alternate blinking)	Wireless hardware error
★ (ON 150ms/OFF 150ms alternate blinking)	×	Connecting through wireless
○	○	Initializing when power comes ON

Left side as seen from the motor side

Check in status LED on motor drive DC power supply

○: Light ON, ×: Light OFF, ★: Blinking

Status LED				Status	Drive source	ALM signal (1) output status
ALM	A0	A1	A2	Status	Drive source	ALM signal (1) output status
×	×	×	×	Normal	-	ON
×	★	×	×	Internal relay life count warningNote 1	No Cutoff	ON
×	×	★	×	Electrolytic capacitor life warningNote 1	No Cutoff	ON
×	×	×	★	Fan revolution drop warningNote 1	No Cutoff	ON
○	○	×	×	Motor power supply voltage drop	No Cutoff	OFF
○	×	○	×	Fan Error Detection	Cutoff	OFF
○	×	×	○	Excess regenerative electric discharge	Cutoff	OFF
○	○	○	×	Motor power supply excess voltage	Cutoff	OFF
○	○	×	○	PC board temperature error	Cutoff	OFF
○	×	○	○	Power device overheated	Cutoff	OFF
○	○	○	○	Critical malfunction	Cutoff	OFF
○	○	○	○	Initializing when power comes ON * Both PWR and MP are on	-	OFF

*1 *ALM Signal is a signal of the break contact output.
Note 1 If warnings occur at the same time, multiple LED lamps will flash at the same time.

Check for abnormality in the master device (PLC, etc.)
Check on 100V AC or 200V AC voltage supplied to DC power supply for motor drive voltage
Check for momentary power failure, voltage drop, power failure, etc.
Check in voltage of 24V DC control power supply
Check for momentary power failure, voltage drop, power failure, etc.
Confirm the generated alarm
Check the alarm information with the teaching tool.
Check the connectors for disconnection or incomplete connection
Check the cables for connection error, disconnection or snagging
Cut off the main power supply of the equipment (to avoid electric shock) and remove the cables around the measurement point (to avoid conductivity through the surrounding circuit) before checking the conductivity.
Check the I/O signals
Use the master device and ELECYLINDER teaching tool to check for inconsistency or abnormality in the input/output signal status of the two units.
Check the noise elimination measures (grounding, connection of noise suppressor, etc.)
Check the events leading to the occurrence of the problem, as well as the operating conditions at the time of occurrence
Analyze the cause
Countermeasures

Caution

When troubleshooting, exclude normally functioning parts from the targets to narrow down the causes.
First, check 1. to 10. so that countermeasures can be taken swiftly.
