Good quality
It is an excellent product and very well protected inside the packaging, before connecting. TO AVOID DAMAGING THE MOTOR, FIRST PROGRAM THE INVERTER, OTHERWISE YOU DAMAGE YOUR SPINDLE !, at least these parameters You need to set up the inverter (you must do it step by step): F013 = 8 (reset up the inverter) // F005 = 400 // F004 = 400 // F003 = 400 // F072 = 400 (Knob working: F002 = 1; F070 = 1)
