13.3.7 CAM command
The CAM command is an alias of parameter K205 which globally diminishes by a certain percentage the
cinematic quantities such as speed, acceleration and jerk time of a movement (but not the position to reach).
Similarly, time quantities such as time, lapse of time between two movements with the WTT command,
execution time of a look-up table movement, etc., are increased in the same proportion. The formulae which
calculates the new values of these quantities according to the number included in the CAM command are given
below.
For cinematic quantities the formula is as follows:
• speed:
• acceleration:
For time quantities the formula is:
Remark: CAM alias use the same syntax than parameter K205. Refer to §6.3
for more information about
the syntax and the possible operators.
The value programmed with the CAM command remains always active. In order to come back to
the basic values the command CAM.1=100 must be entered.
Example:
MMD.1=1 ;S-curve movement selection
ACC.1=500000 ;Definition of a
max
.
SPD.1=200000 ;Definition of v
max
.
POS.1=300000 ;The motor moves to the position 300000 with an acceleration of 500000 and a speed
of 200000.
CAM.1=20 ;Global diminution to 20%.
POS.1=5000 ;The motor moves to the position 5000 with a speed and an acceleration decreased
of 80%. Only 20% of these values are kept. The new speed will be:
[usi] and the new acceleration will be:
[uai].
13.3.8 STE command
The STE command (STEp) is a command which enables the motor to make jump movements. It is used by the
ETEL Tools program to find out the right values of the regulator different gains.
