Corrective action
• The speed of linear encoder has
exceeded the range of use.
• Change the speed of linear
encoder within the range of use.
• Noise entered. • Take the noise reduction
measures.
• Alarm of the linear encoder. • Contact with the linear encoder
manufacturer.
2061
(AL.2A)
Linear encoder
error 1
• Defective installation positions of the
scale and head.
Any time during
operation
• Adjust the positions of the scale
and head.
• The connector CN2L is disconnected. • Connect correctly.
• Faulty of the load side encoder cable • Repair or change the cable.
• Wrong wiring of the load side encoder
cable
• Review the wiring connection.
• The load side encoder cable type (2-
wire, 4-wire) selection was wrong in the
parameter setting.
• Correct the setting in the fourth
digit of parameter No. PC26

2070
Load side
encoder error 1
• The startup timing is slow.
(For the load side encoder with the
external power supply input)
• Servo amplifier
power on.
• Multiple CPU
system power on.
• Make the startup timing of the
external power supply fast.
• Faulty of the load side encoder cable • Repair or change the cable.
• Wrong wiring of the load side encoder
cable
• Review the wiring connection.
2071
Load side
encoder error 2
• The power supply voltage dropped.
(For the load side encoder with the
external power supply input)
• Check the power supply capacity
and voltage.
2088

Watchdog
• CPU, parts faulty
Immediate
stop
• Replace the servo amplifier.
• Bttery cable for absolute position
detection system is open.
• Repair the cable or replace the
battery.
2102
(AL.92)
Open battery
cable warning
• Voltage of battery for absolute position
detection system supplied fell to about
3V or less.
(Detected with the encoder.)
• Replace the battery.
• After home position return, droop pulses
remaining are greater than the in-
position range setting.
• Re-try the home position return.
2106
(AL.96)
Home position
setting warning
• Creep speed is high. • Reduce the creep speed.
2116
(AL.9F)
Battery warning
• Voltage of battery for absolute position
detection system installed to servo
amplifier fell to 3.2V or less.
(Detected with the servo amplifier.)
• Replace the battery.
2140
(AL.E0)
Excessive
regenerative
warning
• There is a possibility that regenerative
alarm [2030] may occur.
(Detected 85[%] regenerative level of
the maximum load capacity for the
regenerative register.)
• Refer to the details on the
regenerative alarm [2030].
2141
(AL.E1)
Overload
warning 1
• There is a possibility that overload alarm
[2050], [2051] may occur.
(Detected 85[%] overload level.)
Any time during
operation
Operation

• Refer to the details on the
overload alarm [2050], [2051].
