Clamps

Ramped Clamp

Description	Ramped Clamp Requires *dwOption-05, Process Control. Following the rising edge of the Enable* signal, the actual output clamps ramp from zero to the upper and lower clamps, according to the Ramp Time. The internal Ramp parameter ramps from zero to 100% and is multiplied by the upper and lower clamp values to produce the actual output clamps.
Availability	Available only in the dw2xx & dw2xx-v2 series products Requires library: Process Control (option -05) Firmware versions 0x2024 and later

Parameters

Input	Input, Read-write, Analog (signed 16-bit integer) -327.67 % to 327.67 %
Upper Clamp	Input, Read-write, Analog (signed 16-bit integer) -327.67 % to 327.67 % Ramped Clamp - Upper Clamp The function block output can not exceed this value. The actual, active clamp is the product of Ramp and this value.
Lower Clamp	Input, Read-write, Analog (signed 16-bit integer) -327.67 % to 327.67 % Ramped Clamp - Lower Clamp The function block output can not be less than this value. The actual, active clamp is the product of Ramp and this value.
Ramp Time	Internal Parameter, Read-write, Time or Rate (signed 16-bit integer) 0.1 s to 3000.0 s Ramped Clamp - Ramp Time The actual upper and lower clamps are the product of Ramp and their preset values. Select units, either 100% ramp time in seconds, or ramp rate per second, %/s.
Enable	Input, Read-write, Boolean (signed 16-bit integer) Ramped Clamp - Enable The clamps and the Ramped Clamp Output are immediately reset to zero while this parameter is inactive, Reset Ramping begins at the rising edge of this input. 0 = Reset 1 = Enable
Ramp	Internal Parameter, Read-only, Set to default on hard initialization, Analog (signed 16-bit integer) 0.00 % to 100.00 % Ramped Clamp - Ramp Read-only. Increases from zero to 100% according to the ramp time / rate, following the rising edge of Enable.
Output	Output, Read-only, Set to default on hard initialization, Analog (signed 16-bit integer) -327.67 % to 327.67 % Ramped Clamp - Output Read-only. Equal to Ramped Clamp Input when not limited by the active clamps.
