Axis type
Encoder type I Enter the type of encoder you are using in this field. You have a choice
between two types of encoders:
IP-STOP if I When an error occurs during execution of the STEP 5 program, it is
CPU-STOP sometimes best to stop the IP. You can do so by entering "yes" in this
field or selecting "yes" with <F7>.
Active modes are interrupted with STOP.
This aborts all active modes except mode 4.
Gain factor I This factor defines the gain factor for the position controller in the unit
1/sec. The permissible value range for the gain factor is from 0.1 to 99.9,
although system limitations or machine data specifications (such as the
resolution or the maximum speed) preclude the use of some of these
values in the majority of cases.
Backlash comp. I This value is added to the travel distance on each traversing (machining)
value movement that involves a reversal of the direction of travel, thus
enabling compensation of backlash outside the control loop (drive
backlash). The backlash is compensated only when there is positive
mechanical coupling between drive and slide. When a reference point is
approached, this may be the case immediately following the approach.
Otherwise, you must program the movement yourself.
