SA3100 Drive Configuration and Programming
C.4 Volts per Hertz Frequency Point Gain Variables
These seven gains below represent the seven frequency points of the V/Hz
characteristic curve. Output voltage varies with output frequency according to the
V/Hz characteristic.
When the enable tuning command (register 100/1100, bit 1, PMI_TUN@) is asserted,
these gains are reset to their default values. When the reset is complete register 200,
bit 1 (PMI_ATC@) is set
See Appendix E (Figures E.2 and E.3) for more information on the V/Hz characteristic.
P5VT_E3! Point 5 Voltage
This value is set to select the voltage at point 5
in the V/Hz characteristic curve.
This value is entered in times 1000, e.g., 50
volts is entered as 50000.
Units: Volts
1000
Default Value: 0
Low Limit: 0
High Limit: 1000000
Step: 1
P6VT_E3! Point 6 Voltage
This value is set to select the voltage at point 6
in the V/Hz characteristic curve.
This value is entered in times 1000, e.g., 50
volts is entered as 50000.
Units: Volts
1000
Default Value: 0
Low Limit: 0
High Limit: 1000000
Step: 1
P0HZ_E3! Point 0 Frequency
This value is set to select the frequency at
point 0 in the V/Hz characteristic curve.
Note that P0HZ_E3 is always 0 (zero) Hz.
Units: Hz
1000
Default Value: 0
Low Limit: 0
High Limit: 0
Step: 0
