Parameter
Description
A position deviation fault is generated when the deviation between the position command and the
actual feedback during motor operation exceeds this threshold.
The position deviation during normal operation varies according to the settings of action speed, gain,
feedforward, etc. Therefore, in actual use, it is set by the following formula.

c
F
: Maximum frequency of position command pulses (pulse/s).
p

: Position loop gain (1/s).
1.2 to 2.0: Safety factor (protection against frequent excessive position deviations)

Parameter
Description
This parameter sets the excessive position deviation warning threshold, when the current position
deviation value >
Pn264 × Pn266
100
When the current position deviation value is >, the drive generates
a position deviation too large warning.
Pn267

Parameter
Description
When the position deviation exceeds this function code value at the moment of servo ON during
motor action, the drive will generate a servo ON position deviation too large fault.
