Description
Notes
0x07030100 1 Logical Axis INT Closed-Loop Control
Mode
0 = hardware
1 = PID algorithm (position control)
2 = Advanced Piezo Control (APC)
algorithm, licence must be ordered
separately
6 = PID velocity control (a position sensor
signal is used, the target is given as
velocity)
7 = PID position control with subordinate
velocity control (a position sensor
signal is used, the target is given as
position)
For axes driven by PiezoWalk® drives, the
PID algorithm for position control
(mode 1) must be selected.

Channel
FLOAT Special Relax Process
Gain
Specifies a gain value for the iterative
relax procedure. Change the default value
only after consultation with PI!
See p. 12 for further details.
