PX41 LMCD Lost motion compensation timing
(Note) Set the lost motion compensation timing in increments of 0.1 ms.
You can delay the timing to perform the lost motion compensation for the set time.
This parameter is supported with software version B4 or later.
PX42 LMCT Lost motion compensation non-sensitive band
(Note) Set the lost motion compensation non-sensitive band. When the fluctuation of the
droop pulse is the setting value or less, the speed will be 0. Setting can be changed
in [Pr. PX40]. Set the parameter per encoder unit.
This parameter is supported with software version B4 or later.
PX43 **STOD STO diagnosis error detection time
Set the time from when an error occurs in the STO input signal or STO circuit until
the detection of [AL. 68.1 Mismatched STO signal error].
When 0 s is set, the detection of [AL. 68.1 Mismatched STO signal error] is not
performed.
The following shows safety levels at the time of parameter setting.

When the short-circuit connector is connected to the CN8 connector, set "0" in the
parameter.
This parameter is available with servo amplifiers with software version C1 or later.
Note. MR-J4W2-_B servo amplifier is "for manufacturer setting".
