ENABLE INT | EXT -
USR / A version EXT
This function enables or disables the use of external enable on pin 12.
With ENABLE = INT, the card enables the output power stage automatically after the power-on
(with a delay time of approx. 0.5s).
This parameter is available only for A version of EDM-M card.

Signal scaling example:
With an EDM-M2**/30E0-* the available signal type is -10 … 0 … +10V.
If application signal is 0…2.5…5V this means:
▪
0% signal for the valve must be moved from 2.5V (application 0%) to 0V - >
SIGNAL_OFFSET = Standard Offset
– Application Offset = 0 - 2.5 = - 2.5 V
▪
Signal input must be scaled from 2.5V to Standard Full Scale of 10V - >
SIGNAL_GAIN = Standard F.S. / Application F.S. = 10 / 2.5 = 4.0
