Parameter Descriptions Parameter Descriptions
REMOTE SETPOINT 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
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
MAX SPEED CLAMP Range: 0.00 to 100.00 %
Maximum value for SPEED DEMAND.
MIN SPEED CLAMP
MIN SPEED CLAMP Range: -100.00 to 0.00 %
Minimum value for SPEED DEMAND.
TRIM IN LOCAL
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
REMOTE REVERSE Range: FALSE / TRUE
Demanded direction when in Remote Reference mode. This is usually connected
directly to the Sequencing Logic.
SPEED DEMAND
SPEED DEMAND Range: xxx.xh % (h)
Indicates actual speed demand. This is the input to the frequency controller.
SPEED SETPOINT
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
REVERSE Range: FALSE / TRUE
Indicates demanded direction. This may not be the actual direction as no account of
setpoint sign is taken.
LOCAL SETPOINT
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.
