Hello, In the SPEC of the Figure 6. Maximum Peak Output Voltage vs Load Resistance, it shows the VOM vs. RL.
However, the max. RL is 10K Ohm. What happens if the RL goes up to 100K Ohm? Very thanks.
Application: Industrial Motor

Brian,
Almost nothing happens. As the curve approaches 10k it is flattening out. Going to 100k and beyond, the curve continues to flatten. 100k only gains a little voltage that would be hard to see on figure 6 chart.
Here is TL082 at +/-5V chart where it is easier to see voltage and gets closer to 100k. This chart also separates VOL and VOH. The lower supply voltage makes lower load current which emulates a higher resistance at +/-15V. TL074 will be similar to this.
Do you need a low cost rail to rail output alternative?
