Trouble shooting when alarm occurs
8-13
■
Alarm Code 53 (Dynamic Brake Resistor Overheat)
Status at the time of alarm
Cause
1
2
Issued when power supply control is turned ON.
✔
Issued during operation.
✔
✔
◆
Corrective actions
Cause
Investigation and corrective actions
1
■
Defect in internal circuit of driver.
■
Replace the driver.
2
■
Dynamic Brake operation frequency
exceeded.
■
Use the dynamic brake so as not to
exceed the permissive frequency.

Alarm Code 54 (Built-in Regenerative Resistance Overheat)
Status at the time of alarm
Cause
1
2
3
Issued when power supply control is turned ON.
✔
✔
Issued during operation.

◆
Corrective actions
Cause
Investigation and corrective actions
1
■
Defect in internal circuit of
driver.
■
Replace the driver.
2
■
Regenerating power
excessive.
■
Check the built-in regenerative
resistance absorption power
■
Check the operating conditions, so
that regenerating power is within
permitted absorption power.
■
Use an external regeneration
resistor.
3
■
Improper wiring of built-in
regeneration resistor.
■
Confirm improper condition and
repair if necessary.
✔
When using a regeneration resistance built in the driver, make sure to set
“
built-in regeneration
resistance
”
at system parameter ID02 [Regenerative Resistor Selection]. This setting makes the
judgment between enabled/disabled of the overheating protection detection treatment of the built-in
regeneration resistance. W hen
“
No connected regenerative resistance or external regenerative
resistance
“
is selected, overheating of built-in regenerative resistance is not detected.
Therefore, there is a danger that built-in regenerative resistance will burn out or be
damaged.
