Ramp function
Information on ramp function
- Three command value inputs
UE I differential input (b20 = 0...±10 V, z20 = 0 V)
UE II (z10) and UE III (z12) related to control zero and with summing effect
- Selection of internal and external ramp time setting via control input UT ext. (z6), LED display on front plate
- Ramp increase time adjustable by means of a switch at the front plate
- Connection and shut-off of the ramp function via control input "ramp off" (z14), LED display of operating mode on the front plate
- Internal ramp time setting via potentiometer on the front plate: Acceleration – Deceleration
- External ramp time setting via voltage-controlled differential inputs UT: Acceleration (b16) – Deceleration (b18)
- Signal output "Ramp timeout" in case of UE = 0 (z18; open collector output to +UA)
LED display on front plate
- Setting: Sensitivity
QA/QB – Limitations in the range 100…50 % Qmax.
- Automatic quadrant recognition in the transition of the valve from one quadrant to the other one – thus only one setting potentiometer and/or one control voltage for the ramp time presetting for acceleration and deceleration each.
