1) Input Voltage: 220V±15% 2) Output Voltage ? 208-240VAC (analogous to Input Voltage) 3) Input Frequency: 48-63 Hz 4) Output Frequency: 0-400 Hz 5) Input Phase: Single phase 6) Output Phase: 3 phase 7) Warranty: 1 year Set up: PD001 = 0 (1 for external control) PD002 = 0 PD003 = 400 ( =300 if the spindle rate is 300) PD004 = 400 ( =300 if the spindle rate is 300) PD005 = 400 ( =300 if the spindle rate is 300) PD141 = 220V ( check the spindle rate) PD142 = 11.0 PD144 = 1440 ( you can set to 2000 or 2400 it should be less than 3000)
