P4-17: Utility Start Delay
Sets the delay time after power up until the drive will recognize a Run command present within one second of power up or
when the Run command is jumpered on the terminal strip.
This is useful in preventing a peak power surge when multiple drives power up and begin accelerating simultaneously. This
function works when the drives all have different P4-17 settings to spread out the power draw during acceleration.
If the Run command is removed and reapplied during the P4-17 time, the drive will cancel the utility start delay and immediately
begin running.
The Utility Start Delay is applied when the drive is auto-restarting after an Undervoltage (Uv), Overvoltage (ov), Power Supply
Over Voltage (Aov), Power Supply Undervoltage (AUv) or a Power Supply Frequency Fault (Fdv) condition.
