2.2KW water cooled spindle and Altivar 12 2.2kW 230V 1ph to 3ph

Hi Jazz,

I did not wire the spindle, but I think if I put live to R/L1 and neutral to S/L2/N and earth to ground main side and UVW to spindle side I will be OK.
Spindle is 24000 RPM, 400HZ, 220V, 8.5A, 3 phase.
My problem lies on the parameter side. I read the manual and I am not to confident which parameter I need to change and with what.
Can you help?

Thank you
Gabi

Hi,

there are usually only 4 important parameters:

• Basefrequency (400Hz) - if you leave this to 50Hz you spindle may have a very short life.
• Maxfrequency (400Hz) - so you're able to reach 24000rpm
• Minfrequency (100Hz) - sets the lowest rpm (6000 rpm). You an go a bit lower but the spindle will have close to no torque below this point anyways.
• Acceleration (and deceleration) time (1 or 2 seconds are OK)

Be careful - VFDs are no toys - they can kill you even if you have an RCD installed in your house.
