1: In GX Configurator-QP, the QD75P N/QD75D N are recognized as the QD75P /QD75D . Therefore, the
setting ranges are the same as those of the QD75P
/QD75D . To set a value outside a setting range in GX
Configurator-QP, set it through a sequence program or GX Works2. The setting ranges in GX Works2 are the
same as those in sequence programs. (Refer to Appendix 1.2)
2: For Select type, refer to GX Configurator-QP Operating Manual.
Pr.8
Speed limit value
Set the maximum speed during positioning and OPR operations. If the specified
speed exceeds speed limit value, positioning will be limited at the speed limit value.
Set the speed limit value within the range of the following formula. If the speed limit
value exceeds the range, the error "Out of speed limit value range" (error code: 910)
will occur.

1) If the positioning speed is set lower than the parameter-defined speed limit
value, the actual acceleration/deceleration time will be relatively short. Thus,
set the maximum positioning speed equal to or only a little lower than the
parameter-defined speed limit value.
2) These settings are valid for OPR, positioning and JOG operations.
3) When the positioning involves interpolation, the acceleration/deceleration time
defined for the reference axis is valid.
