.9.2. guider type
This parameter is used to determine which type of guider will be
used.
0= on a proportional guider a specific motion speed is output to cor-
rect the guiding difference in the event of a deviation of the actual
position from the set position.
1= on an integral actuator a specific actuator position is output to cor-
rect the guiding difference.
2= in master slave mode a DC actuator (slave) exactly follows up
another DC actuator (master). This value 2 may only be set in the
control card for the slave.
3= for applications with an actuator with three-level action
(e.g. reversing contactor).
.9.3. control mode
In the case of web center guiding systems with motor-driven sensor
following-up (hybrid) value 1 must be set.
