A - 38 Parameters, Variables and Commands Ver. 0002
PP150 Os (S150) ReferenceOffset1
Function: Parameter setting the position of the reference mark with respect machine reference
point (home) according to the motor feedback. It is similar to parameter "REFSHIFT"
(P47) for the 8050/55 CNC axes, except that it does not move to return to the position
of PP52 -S52- ReferenceDistance1, "REFVALUE" (P53) at the CNC.
Valid values: -214 .. 214 m
Default value: 0 m
PP151 Os (S151) ReferenceOffset2
Function: Parameter setting the position of the reference mark with respect machine reference
point (home) according to the direct feedback. It is similar to parameter "REFSHIFT"
(P47) for the 8050/55 CNC axes, except that it does not move to return to the position
of PP52 -S52- ReferenceDistance1, "REFVALUE" (P53) at the CNC.
Valid values: -214 .. 214 m
Default value: 0 m
PP159 O (S177) MonitoringWindow
Function: It sets the maximum range for the following error. When the following error exceeds
the value given by PP159, the drive issues error 205 ExcessivePositionDeviation
(DV1 -S11-, Bit 11). If this parameter is set to "0", the following error is not monitored.
It is very important to give it a value other than "0" to prevent the axes from running
away out of control. At the CNC, this maximum following error range is monitored by
setting its relevant parameters for each axis.
Valid values: 0 .. 214 m (0 = the following error is not monitored)
Default value: 30 mm
PP177 O (S177) AbsoluteDistance1
Function: For motors with absolute encoder. It indicates the distance between the zero position
for the drive and the theoretical zero according to the absolute feedback of the
encoder.
Valid values: 214 .. 214 m
Default value: 0 m
PP178 O (S178) AbsoluteDistance2
Function: For absolute direct feedback. It indicates the distance between the zero position for
the drive and the theoretical zero according to the absolute feedback of the encoder.
Valid values: 214 .. 214 m
Default value: 0 m
PP216.# (S296.#) VelocityFeedForwardPercentage
Function: It sets the percentage of velocity Feedforward to be applied. It is similar to "FFGAIN"
(P25) for the axes of the 8050/55 CNC. It indicates the % of velocity command
anticipated to the movement independent from the following error (open loop).
Valid values: 0 .. 120%
Default value: 0% (Feedforward is not applied)
PP217.# (S348.#) AccelerationFeedForwardPercentage
Function: (Not available yet)
It sets the percentage of acceleration Feedforward to be applied.
Valid values: 0 .. 120%
Default value: 0% (Feedforward is not applied)
