Parameters
P5.078
Default:
Unit:
8
Format:
Settings:
Sets the moving pulse amount of the synchronous Capture axis between two capturing actions. The new
value can only be written to the parameter when Capture is not in operation (P5.039.X [Bit 0] = 0).
P5.079■
Default:
Unit:
Format:
Settings:
When the synchronous Capture axis is operating, the pulse error should be 0. Each time when capturing
data, the synchronous axis operates and this parameter updates once. It operates as follows:
P5.079 = incremental pulse amount between two capturing actions (monitoring variable 51h) minus
interval pulse number between each synchronous Capture action (P5.078). You can also write the offset
of the synchronous axis to this parameter. When the synchronous Capture axis is the master axis for the
rotary shear, modifying this parameter can shift the cutting position to the left or right. You can also use
P1.016 (error offset compensation for synchronous Capture axis) to achieve this effect.
Note: monitor the pulse error for synchronous Capture axis with the monitoring variable 084(54h).
P5.080
Default:
Unit:
Format:
Settings:
This parameter limits the correction percentage (%) of the synchronous Capture axis. Correction rate =
Pulse number output by the synchronous axis / Pulse number input by the synchronous axis.
(100 - P5.080)% < Correction rate < (100 + P5.080)%
When the correction rate is bigger, the synchronous error falls to 0 faster, but the speed change is more
drastic. When the correction rate is smaller, the synchronous error becomes 0 slower, but the speed
change is smoother. In the rotary shear application, after adjusting the synchronous error of P5.079,
the bigger the parameter value is, the faster the cutting position reaches the target position. However,
the speed will not be synchronized.
