Example:
Selected transducer type P399BAA-1C. Pressure range: 0-500psi
P1: Set point range =250psi
P2: Proportional bands = 50psi
Then the fan motor starting point ( min speed) =Set point (P1) - Proportional band (P2) =
250-50=200psi
Fan motor max speed at P1=Set point=250psi
Thus as soon as the pressure transducer input reaches 200psi, the motor starts at
minimum speed, and after reaching 250 psi, the motor reaches Max speed.
Therefore if the Set point (Pr 61) was set to 50% and the Proportional Band (Pr 62) was
set to 10%. This would mean that the drive would run at 60Hz when the input is 2.5V
and at 0Hz when the input is 2V (using the 0 to 5V input range).
Enter the motor current rating (taken from the motor name plate).
The drive rated current is the 100% RMS output current value of the drive. This value
can be set to a lower value but not to a higher value than the drive rated current.
Enter the rated full load speed of the motor (taken from the motor name plate).
The motor rated speed is used to calculate the correct slip speed for the motor.
Enter the motor rated voltage (taken from the motor name plate).
This is the voltage applied to the motor at base frequency.
Enter the motor rated power factor cos ϕ (taken from the motor name plate).
Minimum motor speed and motor action as minimum speed cannot be set in this mode.
NOTE
The VFD66 has line start with a single auto restart after 25s.
The drive can be stopped by pressing the stop/reset button. However, before the drive
can be restarted in either Std or EPt mode, the mode will need to be changed.
