3-90
Function:
Scales the minimum output of the selected analog signal on terminal X30/8. Scale the minimum
value as a percentage of the maximum signal value, i.e., 0 mA (or 0 Hz) is desired at 25% of the
maximum output value and 25% is programmed. The value can never be higher than the corre-
sponding setting in par.6-62 Terminal X30/8 Max. Scale
This parameter is active when option module MCB 101 is mounted in the adjustable frequency drive.
Function:
Scales the maximum output of the selected analog signal on terminal X30/8. Scale the value to the
desired maximum value of the current signal output. Scale the output to give a lower current than
20 mA at full scale or 20 mA at an output below 100% of the maximum signal value. If 20 mA is
the desired output current at a value between 0%–100% of the full-scale output, program the
percentage value in the parameter, i.e., 50% = 20 mA. If a current between 4 and 20 mA is desired
at maximum output (100%), calculate the percentage value as follows:

Function:
Contains the value to apply to the output terminal when it is configured as [Bus Controlled].
Function:
Contains the value to apply to the output terminal when it is configured as [Bus Controlled Timeout]
and timeout is detected.
