During Startup
Fault Symptom
Cause
Confirming Methods
Set the S-ON
signal to ON.
The operation
panel displays "Er.
xxx".
Remove the fault.
Shaft of the servo
motor is in free
running status.
1. The S-ON
signal is invalid.
Set operation panel to servo status display and view
whether the operation panel displays "rdy" rather than
"run".
Check whether any parameter in groups H03 and
H17 is set for FunIN1(S-ON). If yes, check that the
corresponding DI is set to ON. If not, allocate the
function and set the corresponding DI to ON. See
group H03 in Chapter 7 for details on setting of input
terminal parameters.
If a parameter in group H03 has been set for
FunIN1(S-ON) and logic of corresponding DI is logic,
but the operation panel still displays "rdy". In this case,
check whether the DI terminal is connected correctly
by referring to Chapter 3 in the IS650P User Manual.
2. Selection of
control mode is
incorrect.
Check whether H02-00 is set to 0. If it is set to 2
(torque mode), motor shaft must be in free running
status because default torque reference is 0.
After the preceding causes are removed, the operation panel should display "run".
