text: <s>[INST] DC DRIVE 20P41AD250RA0NNN Hello everyone. I have problem with a new DC drive, I conencted the control power in terminal U1 V1 220 VAC , The two gren leds are light, ACT and PWR , but the HIM and 20 comm dont turn on. The drive was in our warehouse how back up. I attached picture. [/INST] morera, you should apply power to the control circuits (terminals U2 and V2) of the drive. See the following technote: QA31235 - PowerFlex DC: Input power and control power Here is an excerpt: In addition to the 230 VAC or 460 VAC 3-phase input power, the PowerFlex DC drive also requires 115 VAC or 230 VAC control power at terminal blocks U2 and V2. This powers the internal power supply that produces the logic levels for the regulator board and peripherals and powers the HIM.
