605C Frequency Inverter
SETPOINT SCALE
This function block simply converts the
way the setpoint is expressed from being a
percentage of the MAX SPEED to a
percentage of LIMIT FREQUENCY (refer
to the FLUXING function block).
Functional Description
The setpoint scale block changes the format in which the setpoint is expressed. The function
blocks on the input side of this block process the setpoint as a percentage of maximum speed.
The function blocks on the output side of this block process the setpoint as a percentage of the
LIMIT FREQUENCY.

Parameter Descriptions
INPUT
Range: -300.00 to 300.00 %
The setpoint delivered by the re-wired function block portion of the Inverter’s application.
MAX SPEED
Range: 0.0 to 480.0 Hz
The physical motor speed equivalent to a setpoint demand of 100.00%. Note that the motor
speed in revs per minute, (RPM), is related to the speed in Hz according to the equation:
speed in RPM
=
(speed in Hz) x 2 x 60
