l
Activate with CCTRL-TPIN/E4 = LOW
l
Enter the position of the touch probe sensor at input CCTRL-TP-POS.
l
With a L->H transition at input CCTRL-TPIN the drive synchronizes to the set position of the
output CCTRL-PHI-SET.
7.6.15.3 Reset of main position setpoint
CCTRL-PHI-SET = CCTRL-PHI-ACT is set with CCTRL-RESET = HIGH .
Stop!
Danger! Ensure that the drive is inhibited.
7.6.15.4 Speed precontrol
With speed precontrol, faster control circuits are activated earlier. It should be used if the drive
generates a contouring error during acceleration (negative or positive).
l
Via the input CCTRL-NRED the precontrol can be decreased or increased proportionally to
the phase setpoint change dj/dt.
l
Values > 100% have the effect of a gain on the precontrol.If the values are too high, the drive
operates too fast in dynamic processes or becomes instable.
l
Values < 100% have a damping effect on the precontrol. If the gain is not high enough, a
contouring error (drive too slow) will occur during acceleration or deceleration of the drive.
Note!
The input value at CCTRL-NRED is processed further as absolute value, i.e. neg. values are
interpreted as being positive.
