Error and Maintenance
34 Overrun limit error Occurs during operation.
· The Overrun Limit
Setting (Pn514) was
exceeded during
operation.
· Adjust the gain.
· Increase the set value
of Pn514.
· Set Pn514 to 0 to
disable the function.
36 Parameter error
Occurs when the power
supply is turned ON.
·
There are data errors in the
parameters that were read.
· Reset all parameters.
· The driver is faulty. · Replace the driver.
37 Parameters destruction
Occurs when the power
supply is turned ON.
· The parameters that
were read are corrupt.
· Replace the driver.
38
Drive prohibition input
error
Occurs when the servo is
turned ON.
Or, occurs during
operation.
· The forward drive
prohibition (POT) input
and reverse drive
prohibition (NOT) input
were both OFF at the
same time.
· Wire correctly.
·
Replace the limit sensor.
· Check whether the
power supply for control
is input correctly.
· Check whether the setting for
Drive Prohibition Input
Selection (Pn504) is correct.
39 Excessive analog input 1 Occurs during operation.
· The voltage input to pin
14 is too high.
