605C Frequency Inverter
REFERENCE
This function block holds all the parameters
concerning the generation of the setpoint
reference.
The generation of reference setpoint is
described in Chapter 4: “Operating the
Inverter” - Control Philosophy.

Parameter Descriptions
REMOTE SETPOINT
Range: -300.00 to 300.00 %
This is the target reference that the Inverter will ramp to in remote reference mode (not
including trim), direction is taken from REMOTE REVERSE and the sign of REMOTE
SETPOINT.
SPEED TRIM
Range: -300.00 to 300.00 %
The trim is added to the ramp output in remote mode (or if TRIM IN LOCAL is TRUE) to form
SPEED DEMAND . The trim is typically connected to the output of a PID in a closed loop
system.
MAX SPEED CLAMP
Range: 0.00 to 100.00 %
Maximum value for SPEED DEMAND.
MIN SPEED CLAMP
Range: -100.00 to 0.00 %
Minimum value for SPEED DEMAND.
TRIM IN LOCAL
Range: FALSE / TRUE
When TRUE, SPEED TRIM is always added to the ramp output. When FALSE, SPEED TRIM
is added only to Remote mode.
REMOTE REVERSE
Range: FALSE / TRUE
Demanded direction when in Remote Reference mode. This is usually connected directly to the
Sequencing Logic.
SPEED DEMAND
Range: xxx.xh % (h)
Indicates actual speed demand. This is the input to the frequency controller.
SPEED SETPOINT
Range: xxx.xh % (h)
Indicates target speed. This will be equal to either LOCAL SETPOINT, REMOTE SETPOINT,
JOG SETPOINT or COMMS SETPOINT. (Refer to the JOG function block for the JOG
SETPOINT parameter).
REVERSE
Range: FALSE / TRUE
Indicates demanded direction. This may not be the actual direction as no account of setpoint sign
is taken.
LOCAL SETPOINT
Range: 0.00 to 100.00 %
Indicates the Operator Station setpoint. It is always a positive quantity; saved on power down.
Direction is taken from LOCAL REVERSE.
