minal X42/7, as a percentage of the maximum signal level. E.g.if a 0 mA (or 0 Hz) is desired at 25% of the maximum outputvalue. Then programme 25%. Scaling values up to 100% cannever be higher than the corresponding setting in par 26-52.26-42 Terminal X42/7 Output Max. ScaleRange: Function:100%* [0 - 200%] Scale the maximum output of the selected analog signal at ter-minal X42/7. Set the value to the maximum value of the currentsignal output. Scale the output to give a current lower than20mA at full scale; or 20mA at an output below 100% of themaximum signal value. If 20mA is the desired output current ata value between 0-100% of the full-scale output, programmethe percentage value in the parameter, i.e. 50% = 20mA. If acurrent between 4 and 20mA is desired at maximum output,calculate the percentage as follows:20m ADesired maximum current × 100 %i.e.10m A : 20m A10m A × 100 % = 200 %26-43 Terminal X42/7 Output Bus ControlRange: Function:0%* [0 - 100%] Holds the level of terminal X42/7 if controlled by bus.26-44 Terminal X42/7 Output Timeout PresetRange: Function:0.00 % * [0.00 - 100%] Holds the preset level of terminal X42/7.In case of a bus timeout and a timeout function is selected inpar 26-50 the output will preset to this level.26-50 Terminal X42/9 OutputOption: Function:Set the function of terminal X42/9 as an analog current output.[0] No operation[100] Output frequency[101] Reference[102] Feedback[103] Motor current[104] Torque rel to lim.[105] Torque rel to rated[106] Power[107] Speed2.
