    I have not been able to get a manual for the 500 unit either.
    Have asked them to fix the missing sections of the english version of their website multiple times without success.

    Edit: PI500 is there. PI150 is not yet available.
    Those were the droids I was looking for.

    Which specification P1150, the 240V version? if so it has not been released AFAIK so I doubt the manual is yet available.

    There's no chinese version of the 150 manual on the website yet either.
    Maybe its still being written?

    There are several versions of the 500 series (High performance, A and C) VFDs
    I think that manual is for the PI500 High performance VFD since the HP series only currently offer one model of a SP to 3P VFD , a 5.5kW version as shown in that manual, the rest are all 3P-3P models
    There are also some physical differences between the models, eg the 500 HP has 8 DIs, but the 500A has only 6.
    I don't anticipate any or many instructional set differences for the smaller power drives kW but one never knows.

    I can only find full Chinese manuals available on line for the 500C and 500A
    The 500C (compressor) manual only refer to 7.5kW 3p-3P units
    http://www.powtran.com/upload/201811...1527295560.pdf
    The manual for the 500A series (so called basic VFD) covers more SP models starting from the SP 400W units.
    http://www.powtran.com/upload/201810...1934549660.pdf
    This is the one I would like to see the manual for ie just how basic is it

    Once we have all the manuals it would be useful if someone was to set up a comparison table comparing a relevant range of features for all their smaller VFDs.

    I had not heard of the Powertran brand. I believe they are quite a good unit I wanted to convert my wood lathe. The speed change was with 5 stepped pulleys and a 1.5hp single phase motor. You cannot control a single phase motor that has a starting cap and centrifugal switch for the start winding. It will cook the VFD on start up. I did while experimenting with a small unit on a small motor. In the end I used a Huanyang HY02D223B 2.2 kw VFD with an optional control panel. I fitted a 3 phase motor to the lathe and set it up with a two step pulley to provide extra torque at low speed. It took a while for me to get my head around everything and set it up. Such a job is not for the faint hearted. I purchased my drive and motor on eBay. WARNING. There a number of units available that are not genuine Huanyang units They are look alike and are not the genuine brand and do not do what they are supposed to. They also lack a lot of adjustments the genuine units have.

    Yes good advice about the fake HYs.

    What size motor did you end up using?

    BTW neither the standard HY units or their clones are Vector controlled so as you say their power below 50Hz are indeed proportional to frequency, so 25Hz = half power and 12.5Hz = 14 power.
    The Powtran units have Vector control capability so the power drops off far less at lower RPMs.
    The still have close to full power down to ~40Hz and about 2/3rds power at 25Hz and 1/2 power at around 15Hz and the still have some power even as low as 5Hz
    This means there's less of or no need to change belts.
    Running continually at significant loads at low RPMs means the motor can easily overheat so an additional motor fan may be needed - even something like a 12V computer PS supply would be sufficient to provide the needed cooling.

    Then if a motor of twice the original power is used you can have the original power from about 12 Hz upwards.
