Hi,
For clarification:

You changed
C10 to 47uF
C11,C12 and C13 to 1uF
R22-R27 to 150

and you replaced U4
Other ObservationsBrake IGBT
You may need to add another IGBT. This IGBT connects a high power resistor across the DC bus if the DC bus too high. The DC bus will rise if you decelerate rapidly. Energy from the mechanical rotation will be transferred back to the bus.
Opto-couplers in the linear mode

The two analog channels for setting speed control and trip level is bad design practice. The transfer function is strongly dependent on the current transfer ratio, CTR, of the opto-coupler.
I suggest that you encode the signals with PWM.
Something like the LTC6992:

Read the datasheet to lower the frequency to around 20kHz.
Filter the signal on the isolated side to obtain the analog voltage.
Isolated supply

These TMR 1211 modules are not really designed to provide
safety isolation from the mains.
The datasheet shows:


The insulation system is
FunctionalThe 1600V dc is for 60s.
Compare to Traco TIM series:

This is safety rated.EMC
You will need to add some EMC countermeasures.
You will need a filter including a CM choke on the input
Probably need RC circuits on the U,V,W outputs
The switching edges from the PWM waveform will be capacitively coupled in the motor to ground.
