Table 432: Parameter 6-61 Terminal X30/8 Min. Scale
6-61 Terminal X30/8 Min. Scale
Default value: 0%
Conversion index: -2
Scales the minimum output of the selected analog signal on terminal X30/8. Scale the minimum value as a percentage of the maxi-
mum signal value. For example, enter the value 25% if the output should be 0 mA at 25% of the maximum output value. The value
can never exceed the corresponding setting in parameter 6-62 Terminal X30/8 Max. Scale if the value is below 100%. This parameter
is active when VLT® General Purpose I/O MCB 101 is mounted in the drive.
Parameter 6-62 Terminal X30/8 Max. Scale
Table 433: Parameter 6-62 Terminal X30/8 Max. Scale
6-62 Terminal X30/8 Max. Scale
Default value: 100%
Conversion index: -2
Scales the maximum output of the selected analog signal on terminal X30/8. Scale the value to the required 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 required output current at a value between 0–100% of the fullscale output, program the
percentage value in the parameter, that is 50%=20 mA. If a current 4–20 mA is required at maximum output (100%), calculate the
percentage value as follows: 20 mA/desired maximum current x 100%
20 − 4
10 mA: × 100 = 160%

Description
Parameter 4-54 Warning Reference Low defines the behavior of the analog output in case of field-
bus timeout.
Parameter 4-54 Warning Reference Low defines the behavior of the analog output in case of field-
bus timeout.
Analog output at 0 torque is 12 mA. Motoring torque increases the output current to maximum
torque limit 20 mA (set in parameter 4-16 Torque Limit Motor Mode). Generating torque decreases
the output to torque limit in generator mode (set in parameter 4-17 Torque Limit Generator Mode)
Example: Parameter 4-16 Torque Limit Motor Mode = 200% and parameter 4-17 Torque Limit Genera-
tor Mode = 200%. 20 mA = 200% motoring and 4 mA = 200% generating.
0 Hz = 0 mA, parameter 4-19 Max Output Frequency = 20 mA.
