EDSVF9383V−EXT EN 2.0
Function
l Offset
– The value at AINx−OFFSET is added to the value at AINx−IN.
– The result of the addition is limited to ±200%.
l Gain
– The limited value (after offset) is multiplied with the value at AINx−GAIN.
– The signal is then limited to ±200 %.
l The signal is output at AINx−OUT.

Special feature of AIN1
l A minimum speed can be set under C0010. The signal gain is reduced such that the signal at
AIN1−OUT = 100 % with a setpoint of 10 V at X6/1 and X6/2.
– Setting range: 0 ... 36000 rpm
– Setting range: 0 rpm (function inactive)
– Input limits: C0010 < C0011
– AIN1−OFFSET and AIN1−GAIN are independent of C0010.
l A dead band element can be integrated into the output signal at AIN1 via C0034. You can
achieve the function 4 ... 20 mA as a current master value together with the jumper setting X2
(controller front).
l The signal at X6/1 and X6/2 is read cyclically (1 ms).
Special feature of AIN2
l The signal at X6/3 and X6/4 is read cyclically (250
ms).
