Parameter Descriptions
RESET VALUE
Range: -300.00 to 300.00 %
This reset value is pre-loaded directly into the output when EXTERNAL RESET is TRUE, or at
power-up. It will be clamped by min and max values.
INCREASE RATE
Range: 0.1 to 600.0 SECS
Rate of change of increasing output value.
DECREASE RATE
Range: 0.1 to 600.0 SECS
Rate of change of decreasing output value.
RAISE INPUT
Range: TRUE/FALSE
Command to raise output.
LOWER INPUT
Range: TRUE/FALSE
Command to lower output.
MIN VALUE
Range: -300.00 to 300.00 %
Minimum ramp output clamp. This is a plain clamp, not a ramped "min speed" setting.
MAX VALUE
Range: -300.00 to 300.00 %
Maximum ramp output clamp.
EXTERNAL RESET
Range: TRUE/FALSE
If EXTERNAL RESET is TRUE, the output of the Raise/Lower block is set to the RESET
VALUE.
