Feasibility. Your original question doesn't clarify that you have already checked. Apparently you did.but what is the relation of this question to my question
Actually it's current that gives the torque, the voltage pushes the current.
the modulation frequency can be 60 Hz or whatever, even down to 0.
Also, I take it that pwm'ing a high voltage to the dc motor means the current rise time in the coils is quicker. (as opposed to just using a lower equivalent average constant dc voltage)
...If you just use a lower dc voltage which on average is the same as the pwm'd one, then you may well stall the motor.But the power delivered in both cases will be same (equivalent average constant dc voltage ensures that) and a 250W dc motor may start a bit faster but the effect may be hardly noticeable. What will be the benefits?
Zero modulation frequency on a VFD will certainly kill the motor. You can ramp the frequency for a soft start effect but ...
If you just use a lower dc voltage which on average is the same as the pwm'd one, then you may well stall the motor.
But back to the chase. What PLC is the OP using, and how is the motor power regulated?
