Vmax = 32 x sqrt( inductance in millihenries )
The html version here (http://www.geckodrive.com/support.html) is good, but the sqrt symbol looks like a V just after Figure 13. The pdf file is clearer.

If it had a 36v supply before & the motor manufacturers have suggested a psu for you to use then maybe best to stick with that if your not sure how to work it all out yourself. If the machine worked fine before the psu failed then stick with what you know.
