Hi, I need to soft start a 1KW 48VDC Motor. I am thinking of using solid state relay with the V350 built in PWM function. I believe the use of SSR with DC motors is not recommended. Could anyone advice what hardware may I use?

I have some problems with analog SSR (Celduc, Carlo-Gavazzi, etc brands) when I try to control from an 4-20mA analog output of OPLC. For example with the V200-18-E2B the load impedance is 500Ω maximum for current output. The input dynamic impedance of the SSR is ≥ 100 Ω but a drop in voltage ≤ 8 VDC @ 20 mA. The application doesn't work from 4-8mA, I suppose the dynamic impedance of the SSR will be higger than 500Ω. I found one solution to use several SSR with an analog output, inserting a Power Suply between the output and the SSR. Do you use it any time? does it secure for the analog output of Unitronics? Look at the image:
