position detection system 
reduced. 

Battery voltage fell to 3.2VDC or less. 

 
 
 

2140 E0 

Excessive 
regenerative load 
warning 

There is a possibility that 
regenerative power may 
exceed permissible 
regenerative power of built-in 
regenerative brake resistor or 
regenerative brake option. 

Regenerative power increased to 85% 
or more of permissible regenerative 
power of built-in regenerative brake 
resistor or regenerative brake option. 

 
 
 
 
 
 

2141 E1 

Over load 
warning1 

There is a possibility that 
overload alarm 1 (error code: 
2050) or 2 (error code: 2051) 
may occur. 

Load increased to 85% or more of 
over load alarm 1 (error code: 2050) 
or 2 (error code: 2051) occurrence 
level. 

 
 
 
 

Noise entered the encoder. 

 
 

2143 E3

Parameter value set from QD75MH 
controller is outside setting range. 

 
 
 

 
 

2146 E6 

Servo forced stop 
warning 

EM1-SG is open. 

Forced stop was made valid. 

(EM1-SG was opened.)

amplifier 

warnings 

2148 E8 

Cooling fan speed 
reduction warning 

The speed of the servo 
amplifier decrease to or below 
the warning level. 
this warning is not displayed 
with MR-J3-70B/100B among 
servo amplifiers equipped with 
a cooling fan. 

The power supply of the cooling fan is 
broken.
