Alarm Status
Segment LED Alarm Code
Display ALM8,4,2,1
Alarm code 0,1 indicates: when Func2/ bit7,6 ="0,0", "0"= output open and "1"= output short.
Operating state when alarm occurred
OPERATING STATE
When control power supply is turned on
When main circuit power supply is turned on
During operation
Corrective Measures
• Allowable regeneration power of built-in
1
regenerative resistor is exceeded.
• Load inertia is too high, or conducted time
(for one cycle) is too short
2 External regenerative resistor is specified, but
bit4 of Func2 is not set properly.
3 Built-in regenerative resistor module is
specified, but faulty wiring.
4 External regenerative resistor module is
specified, but faulty wiring.
5 Faulty regenerative resistor.
6 Resistance value of external regenerative
resistor module is too high
7 Input power voltage is over 280V AC
8 Faulty amplifier control circuit

Review load inertia and operational pattern
• Use an external regenerative resistor module.
• Lower load inertia within specified range
• Increase deceleration time
• Increase conducted time
Set bit4 of Func0 to "1" by allowable absorbing
power of external regenerative resistor.
Check and correct wiring.
Check and correct wiring.
• Replace servo amplifier if using built-in
regenerative resistor module.
• Replace resistor if using external regenerative
resistor module.
Change to resistor that meets specification.
Review input power voltage
Replace servo amplifier.
