Entering Pulse To Stroke Conversion Data; Entering Torque To Pressure Conversion Data - YASKAWA YRC1000 Operator's Manual

1.4.1.1 Entering Pulse to Stroke Conversion Data

1.4.1.2 Entering Torque to Pressure Conversion Data

1 Spot Welding Application Using a Motor Gun
1.4 System Setting (Motor Gun)
To specify the gun stroke in mm, enter data about the relationship
between the gun axis motor encoder pulse value and the gun stroke
(mm).
Follow the procedures explained below.
Up to 12 points of data can be entered.
1. Set the applicable gun stroke by a jog operation with the programming
pendant.
– Read the pulse value of the gun axis motor encoder on the
programming pendant.
2. Repeat the steps 1 for 12 points in total.
– When the relationship between two values are known from the
machine drawing, calculate the data for the 12 points.
3. Enter the obtained data of 12 items in "PULSE" and "STROKE" in the
gun condition file.
To specify the pressure in N, enter data about the relationship between
the gun axis motor torque (%) and the pressure (N).
Refer to chapter 1.3.9
for setting procedures.
When the gun condition file has not been set, the pressure
cannot be applied.
NOTE
When applying the pressure for the first time, set any value
in the gun condition file.
