Parameter 36-42 Terminal X49/7 Min Scale
Table 1332: Parameter 36-42 Terminal X49/7 Min Scale
36-42 Terminal X49/7 Min Scale
Default value: 0%
Conversion index: -2
Match the minimum output of terminal X49/7 with a required value. The required value is defined as a percentage of the value
selected in parameter 36-40 Terminal X49/7 Analogue Output. To know more about how this parameter works, see parameter 6-52
Terminal 42 Output Max Scale. The following example describes how the drive uses this parameter. Example:
•
Parameter 36-03 Terminal X49/7 Mode = [0] Voltage 0–10 V.
•
Parameter 36-40 Terminal X49/7 Analogue Output = [100] Output frequency.
•
Parameter 4-19 Max Output Frequency = 200 Hz.
Application requirement: If the output frequency is lower than 20 Hz, the output of terminal X49/7 should be 0 V. To fulfil the exam-
ple requirement, enter 10% in parameter 36-42 Terminal X49/7 Min. Scale.
Parameter 36-43 Terminal X49/7 Max. Scale
Table 1333: Parameter 36-43 Terminal X49/7 Max. Scale
Parameter 36-43 Terminal X49/7 Max. Scale
Default value: 100%
Conversion index: 0
Scale the maximum output of terminal X49/7. For example, the scaling is done for the following reasons:
• To provide an output value lower than the maximum possible value.
• To provide the full signal range using output values lower than a certain limit.
To know more about how this parameter works, see parameter 6-52 Terminal 42 Output Max Scale. Example:
•
Parameter 36-03 Terminal X49/7 Mode = [0] Voltage 0–10 V
•
Parameter 36-40 Terminal X49/7 Analogue Output = [100] Output Frequency.
•
Parameter 4-19 Max Output Frequency = 200 Hz.
Example case 1: 5 V maximum output is required when the output frequency is 200 Hz. Parameter 36-43 Terminal X49/7 Max. Scale x
100% = 200%. Example case 2: 10 V maximum output is required when the output frequency is 150 Hz (75% of the maximum out-
put frequency). Parameter 36-43 Terminal X49/7 Max. Scale = 75%.
