I had purchased a 90’s era jet surface grinder about a year ago and am finally at the point of wiring up a vfd to power it. Already have a teco 2hp vfd to do the job. While sitting around drawing out the schematics for wiring I started thinking about the programming of the vfd. The problem I’ve run into is once wired in I’m suppose to program the parameters of the motor. The motor and spindle are one unit. Not a spindle Assy. Linked up to the motor via coupler or belts. In the manual it states it’s a 1.5 hp 3450rpm motor that’s it. I looked all over the motor housing and there are no specs listed on the motor anywhere NO nameplate. I do not know the amperage? I remember that’s one of the specs that needs to be load in the vfd. What can I do to either find out the amp draw prior to running or what number to safely put in the vfd without compromising either component? Any info on the matter would be appreciated thanks.
