Electronic pressure transducer input mode
The VFD66 controls work with any electronic pressure transducer that generated a 0-5
Vdc or 0-10Vdc output signal.
The user can configure the drive using Set point (Pr 61) & Proportional Band (Pr 62) and
Max Speed (Pr 02). Note that Minimum Speed (Pr 67) and Action at Min Speed (Pr 64)
cannot be configured in this mode.
