6.5.2.18 GS - Run Gear Shift
Step type Id: 16
Parameters: GS (Gear Shift), TI1 (Time1), TI2 (Time2).
Function: Controls the digital output used for shifting the gear for the currently executed spindle. GS
equal to 1 (one) will cause gearshift output go high when this step is executed. GS equal to
0 (zero) will make the gearshift output go low.
When changing speed from high to low (normal tightening), the spindle will first run reverse
for TI1 seconds, then wait for TI2 seconds before the gear is changed.
When changing speed from low to high the spindle will first run forward for TI1 seconds, and
then wait for TI2 seconds before the gear is changed.
Trace: There are no control parameters for this step type in trace.
6.5.2.19 PLC - Run PLC step
Step type Id: 18
Parameters: DIR, PLC output STEPTYPE, PLC output STEPVAL
Function: This step is configurable during run-time using the PLC. When the PLC sets the start signal
high the PLC Station variables STEPTYPE and STEPVAL are sampled. The first output,
STEPTYPE, controls the type of step that will be executed and the STEPVAL is used as
target value. DIR is the only parameter that is defined in the tightening program and it
controls the direction of the step.
STEPTYPE can take the following values:
A - Run until Angle with Start condition = AS1
STEPVAL should be set to a target value of corresponding type, that is, a torque, an angle,
or a time.
