Name
Absolute position detection system
battery voltage is low.
Zero point return could not be
made to the accurate position.
There is a possibility that
regenerative power may exceed
permissible regenerative power of
built-in regenerative brake resistor
or regenerative brake option.
There is a possibility that overload
1 (error code: 2050) or overload 2
(error code: 2051) may occur.
Absolute position encoder pulses
faulty.
Parameter is outside the setting
range.
EM1-SG open.
Servo system controller
emergency stop was input.
Servo turned ON with main circuit
power OFF.
Definition
1. Battery cable is open.
2. Battery voltage dropped to 2.8V or less.
1. Droop pulses remaining are greater than the in-
position range setting.
2. Zero point return was executed during operation
command.
3. Creep speed high.
Regenerative power increased to 85% of
permissible regenerative power of built-in
regenerative brake resistor or regenerative brake
option.
Load increased to 85% or more of overload 1 (error
code: 2050) or overload 2 (error code: 2051)
occurrence level.
1. Noise entered the encoder.
2. Encoder faulty.
Parameter was set from AD75 to value outside
setting range.
Forced stop was made valid.
(EM1-SG opened)
1. EMG (pin 6) or EMG* (pin 16) in SSCNET cable
is open.
2. Servo amplifier connector faulty
3. AD75 connector faulty
Servo turned ON with main circuit power OFF.
