Ramp generator
2281
• Multiple functions
• Programmable from front
• 3-digit LED display
• NPN and PNP inputs
• Internal ramp time or external pulses
• Reset or preset function
Applications
To convert digital signals to a time-controlled analogue signal with either internally entered up/down time or with external
pulses for up/down function. Can convert digital outputs to analogue outputs. By connection of a 2-phase encoder as up/
down pulse generator the pulses will be converted to an analogue position signal. Especially suitable in applications where
easy 11-pole relay socket mounting is required for instance in a panel. Possibility of readout of the analogue value of the
output through the built-in display.
Technical characteristics
General
The 2281 is microprocessor-controlled and basic-calibrated. This means that the input and output can be programmed acc. to
the requested signal range without any readjustment. Thereby a high degree of accuracy and flexibility are ensured. The user
interface consists of a 3-digit display and 3 function keys in the front. The interface is used to change a function, ramp time or
an output signal range.
Inputs
6 digital inputs make it possible to choose reset, up/down functions as either NPN inputs (short circuit to gnd.) or as PNP input
(+ 24 VDC). The trigger level is typically 8 VDC with a pull up/down resistance of 3.5 kΩ corresponding to a load current of 6.9
mA. Via an analogue switch the up and down inputs can be switched between input filters for a pulse length > 10 ms or > 0.5
ms. The chosen filter is the same for all up/down inputs. The 10 ms filter is used for elimination of contact-bounce. The reset
inputs have a filter for pulse lengths > 30 ms. The arrow keys can be selected to work in parallel with the digital up and down
inputs.
Functions
Ramp generator with internal time measurement
Up ramp and down ramp can be set separately in the time span 0.1...999999 s. Reset can be chosen to preset at any value
between 0 and 100% output signal. The up/down time measurement starts when the time constant of the selected filter has
been exceeded.
If the up/down inputs are activated simultaneously, both ramps will be activated and the outputs rise/fall with the difference
of the times.
Ramp generator with external pulses
Up ramp and down ramp can be adjusted separately with a number of pulses between 1 and 15,615,744. The entered number
of pulses (max. 60999) are multiplied by the prescaler which can assume values between 1 and 256. Reset can be chosen to
preset at any value between 0% and 100% output signal. The pulse length must be longer than the time constant of the
selected filter. If the up/down inputs are activated simultaneously both input pulses will be scanned and the output will rise/
fall with the difference of the pulses. In case of supply drop-out the position will be remembered when the prescaler is 1.

2281V103-UK 3
Ramp generator for 2-phase encoder
The ramp pulses are set to a value between 1 and 15,615,744. The entered number of pulses (max. 60999) is multiplied by
the prescaler which can assume values between 1 and 256. The pulse length must be longer than the time constant of the
selected filter.
When the encoder is turned in one direction the output rises compared to the set number and pulses, when the encoder is
turned in the opposite direction the output falls proportionally.
The reset can be chosen to preset at any value between 0% and 100% output signal. By activating reset for instance in a 50%
position an auto-calibration of the measuring system is obtained. In case of supply drop-out the position will be remembered
when the prescaler is 1.
Output
Analogue standard current output of 0/4...20 mA or, with JP3 off, 0/2...10 mA. The output span can be set to any value within
the standard ranges with a max. offset of 50% of the max. value and a minimum span of 5 mA. Restart after a supply drop-
out can be chosen to generate either the reset value or the value which the output had just before the supply drop-out.
Maximum load is 600 Ω / 12 VDC. By short-circuit of pins 3 and 2 the output current is converted to a standard voltage of
0/0.2...1 VDC, 0/2...10 VDC or special VDC dependent on the size of R65. The voltage signal is available between pins 2 and 1.
See hardware programming for correct choice.
An overrange can be defined thereby enabling the output to exceed the selected signal range by ±3% within the limit of
0...20.5 mA.

Description of functions (selection of application)
4.4 OR Selection of Overrange
If ON has been selected, the output can exceed the selected output span by ±3%. However, only within 0 to 20.5
mA. If OFF has been selected, the output is limited by the selected output span.
Possible selections are ON or OFF.
5.0 APP - Selection of application
5.1 FUn - Selection of function
Common to all functions is the selection of filter (FLt) in menu 5.2. Depending on the selection, the up/down pulse
length must be > 10 ms (50 Hz), or > 0.5 ms (1 kHz).
The reset input has a fixed filter of 30 ms (16 Hz).
At power up the output value can be set to adopt the value it had immediately before power down, or set to adopt
the same value as at reset. The reset value can be set to a value between 0 and 99.9% of the output span.
Possible selections of function are:
001 = Ramp generator with internal time measurement
The up and down ramps can be set separately in the time range 0.1...999999 s. The up/down time measurement
starts when the inputs have been activated longer than the time constant of the connected filter.
If the up/down inputs are activated simultaneously, both ramp times will be measured and the output will decrease/
increase by the difference between the times.
002 = Ramp generator with external pulses
The up and down ramps can be set separately by pulse numbers between 1 and 15,615,744 which are set in menu
2.0 UP/3.0 dO and menu 1.3 PrE respectively.
The values set in menu 2.0 and 3.0 (1...60999) are multiplied by the value set in menu 1.3 (1...256). An up ramp of
75258 pulses is set in menu 2.1 to 37; in menu 2.2 to 629; and in menu 1.3 to 2 (37629 x 2 = 75258). With a pre-
scaler of 2, the number of pulses on the down ramp must also be set as (number of pulses / 2). The up/down pulses
are detected when the inputs are activated longer than the time constant of the connected filter. If the up/down
inputs are activated simultaneously, both input pulses will be read, and the output will increase/decrease by the
difference between the pulses.
003 = Ramp generator for 2-phase encoder
The resolution of the applied 2-phase encoder is doubled, as both the leading and trailing edges on the pulses are
counted. A 2-phase encoder with 100 pulses per revolution which is to be revolved 10 times, must be set to 2000
pulses (100 x 10 x 2). The ramp pulses can be set with a pulse number between 1 and 15,615,744, which is set in
menu 2.0 UP and 1.3 PrE respectively.
Menu 3.0 has no function at a 2-phase encoder. The value set in menu 2.0 (1...60999) is multiplied by the value set
in menu 1.3 (1...256). If the encoder yields 30000 pulses for instance, the ramp pulses must be set to 60000 by
setting menu 2.1 to 60, menu 2.2 to 000, and menu 1.3 to 1 (60000 x 1 = 60000). The ramp pulses are detected
when the inputs are activated longer than the time constant of the connected filter. When the encoder is turned in
one direction, the output increases according to the set number of pulses. When the encoder is turned in the
opposite direction, the output decreases accordingly.
