Good day, does anyone have experience with the ACS355 solar pump drive?
I have some questions on how to set it up correctly and some fault codes that I have.
Three-phase 380V 50Hz supply or 540V DC PV supply Pump 0.55KW 3ph 50Hz 2850 rpm Drive 0.75KW
On PV input.
1. What is the best to set the minimum PV volts? 2. What is the lowest speed or Hz the pump motor can turn before damage to it? 3. Drive remote starts with a float level, the frequency starts from 0Hz to 50Hz in a time frame of 20 seconds, does it always start like this? 4. When PV or DC bus volts low the drive only reaches 30Hz
On three-phase grid input.
1. I get a fault F0004 (short circuit but why on PV input the motor runs?)
