[Pr.438] Cam axis cycle unit setting
Set the command units for the cam axis input per cycle to be used for cam control.
These units are used for setting the cam axis length per cycle and the cam axis current
value per cycle.
There is no influence on the control for the parameter for monitor display.
Refer to Section 4.5.1 for details.
[Pr.439] Cam axis length per cycle
Set the length per cycle of the cam axis to generate the cam axis current value per cycle.
The unit settings are in the cam axis cycle units (Refer to Section 4.5.1).
Set a value within the range from 1 to 2147483647.
[Pr.440] Cam No.
Set the cam No. for cam control.
Cam No.0 operates as a linear cam for 100% of its stroke ratio along the cam axis length
per cycle.
The cam No. can be changed during synchronous control.
The value set in "[Pr.440] Cam No." is valid when the cam axis current value per cycle
passes through the 0th point of cam data, or is on the 0th point.
[Pr.441] Cam stroke amount
Set the cam stroke amount corresponding to a 100% stroke ratio in output axis position
units (Refer to Section 4.5.1) for cam control using the stroke ratio data format.
The cam stroke amount can be changed during synchronous control.
The value set in "[Pr.441] Cam stroke amount" is valid when the cam axis current value per
cycle passes through the 0th point of cam data, or is on the 0th point.
The setting value is ignored for a cam using the coordinate data format.
[Pr.444] Cam axis phase compensation advance time
Set the time to advance or delay the phase of the cam axis current value per cycle in the
cam control.
1 to 2147483647 [μs] ............... Advance the phase according to the setting time.
0 [μs] ........................................ Do not execute phase compensation.
-2147483648 to -1 [μs] ............ Delay the phase according to the setting time.
If the setting time is too long, the system experiences overshoot or undershoot at
acceleration/deceleration of the input speed. In this case, set a longer time to affect the
phase compensation amount in "[Pr.445] Cam axis phase compensation time constant".
