Parameters, Variables and Commands Ver. 0002 A - 35
PP42.# O (S42.#) HomingAcceleration
Function: It is the acceleration applied when the homing operation is controlled by the Drive
itself. This parameter is required when the homing operation is controlled by the
Drive itself: PC148 -S148- DriveControlledHoming active.
Valid values: 0 .. 2140000 rd/sec
2
Default value: 60 rd/sec
2
PP49 Os (S49) PositivePositionLimit
PP50 Os (S50) NegativePositionLimit
Function: They indicate the maximum position (coordinate) that can be reached in the positive
and negative direction respectively.
These limits are only considered when all the position data is referred to Machine
Reference Zero (home).
In other words, Bit 0 of PV203 -S403- PositionFeedbackStatus is "1".
If variable PV58 -S258 TargetPosition exceeds the position limits, the drive activates
bit 13 of DV9 -S12- Class2Diagnostics (Warnings)
TargetPositionOutsideTheTravelZone.
Valid values: -214 .. 214 m
Default value: 214 m (-214 m)
PP52 Os (S52) ReferenceDistance1
Function: When working with motor feedback, this parameter indicates the distance between
Machine Reference Zero point and home. It is similar to parameter "REFVALUE"
(P53) of the axes of the 8050/55 CNC.
Valid values: -214 .. 214 m
Default value: 0 m
PP54 Os (S54) ReferenceDistance2
Function: When working with direct feedback, this parameter indicates the distance between
Machine Reference Zero point and home. It is similar to parameter "REFVALUE"
(P53) of the axes of the 8050/55 CNC.
Valid values: -214 .. 214 m
Default value: 0 m
PP55 O (S55) PositionPolarityParameters
Function: 16-bit register used to reverse the sign of the different position data. When in position
loop, except for the position command, the signs are only changed on the monitored
data and not internally. In the case of turning motors we will consider that if the sign
of the position command is positive, they will turn clockwise. This parameter cannot
be used to solve a positive feedback problem (motor runaway) due to the fact the
second feedback is counting in the opposite direction. That problem is solved using
parameter PP115 -S115- PositionFeedback2Type.
