Definition
Cause
Action
1. Regenerative brake option is not
used.
Use the regenerative brake option.
2. Though the regenerative brake
option is used, the parameter
No.PA02 setting is " 00 (not
used)".
Setcorrectly.
3. Lead of built-in regenerative brake
resistor or regenerative brake option
is open or disconnected.
1. Change lead.
2. Connect correctly.
4. Regenerative transistor faulty.
Change servo amplifier
5. Wire breakage of built-in
regenerative brake resistor or
regenerative brake option
1. For wire breakage of built-in regenerative
brake resistor, change servo amplifier.
2. For wire breakage of regenerative brake
option, change regenerative brake option.
6. Capacity of built-in regenerative
brake resistor or regenerative brake
option is insufficient.
Add regenerative brake option or increase
capacity.
7. Power supply voltage high.
Review the power supply.
33
Overvoltage
Converter bus
voltage exceeded
400VDC.
8. Ground fault occurred in servo
motor power (U, V, W).
Correct the wiring.
1. The SSCNET cable is
disconnected.
Connect it after turning off the control circuit
power supply for servo amplifier.
2. The surface at the end of SSCNET
cable got dirty.
Wipe dirt at the surface away. (Refer to
section 3.9)
3. The SSCNET cable is broken or
severed.
Change the cable.
34
Receive error 1
SSCNET
communication error
(Continuously
communication error
with about 3.5ms
interval.)
4. Noise entered the servo amplifier.
Take noise suppression measures.
1. Command given is greater than the
maximum speed of the servo motor.
Review opration program
2. Servo system controller failure.
Change the servo system controller.
3. Noise entered the servo amplifier.
Take noise of I/O signal suppression
measures.
35
Command
frequency error
Input pulse frequency
of command pulse is
too high.
4. Noise entered the controller.
Take noise from the controller suppression
measures.
1. The SSCNET cable is
disconnected.
Connect it after turning off the control circuit
power supply for servo amplifier.
2. The surface at the end of SSCNET
cable got dirty.
Wipe dirt away from the surface. (Refer to
section 3.9)
3. The SSCNET cable is broken or
severed.
Change the cable.
36
Receive error2
SSCNET
communication error
(Intermittently
communication error
with about 70ms
interval.)
4. Noise entered the servo amplifier.
Take noise suppression measures
1. Servo amplifier fault caused the
parameter setting to be rewritten.
Change the servo amplifier.
2. There is a parameter whose value
was set to outside the setting range
by the controller.
Change the parameter value to within the
setting range.
37
Parameter error Parameter setting is
wrong.
3. The number of write times to EEP-
ROM exceeded 100,000 due to
parameter write, etc.
Change the servo amplifier.
