HX7+ ASD Installation and Operation Manual 101
VI/II Speed Reference #1
Program Frequency Setting Speed Reference Setpoints VI/II
This parameter is used to set the gain and bias of the VI/II input terminal when
the VI/II terminal is used as the control input while operating in the Speed
Control mode or the Torque Control mode.
Note: See note on pg. 57 for further information on the VI/II
terminal.
VI/II Input Speed Control Setup
Perform the following setup to allow the system to receive Speed control input
at the VI/II input terminal:
•Program Fundamentals Standard Mode Selection Frequency
Mode #1 VI/II.
•Program Fundamentals Standard Mode Selection Command
Mode Use Terminal Board.
•Set VI/II Speed Reference #1 (F201) — the input signal level that
represents VI/II Speed Frequency #1.
•Set VI/II Speed Frequency #1 (F202).
•Set VI/II Speed Reference #2 (F203) — the input signal level that
represents VI/II Speed Frequency #2.
•Set VI/II Speed Frequency #2 (F204).
•Provide a Run command (F and/or R).
Once set, as the VI input voltage or the II current changes, the output frequency
of the ASD will vary in accordance with the above settings.
This parameter sets VI/II Speed Reference #1 and is the input signal level that
is associated with the setting of VI/II Speed Frequency #1 while operating in
the Speed Control mode.
VI/II Input Torque Control Setup
Perform the following setup to allow the system to receive Torque control input
at the VI/II input terminal:
•Program Fundamentals Standard Mode Selection Frequency
Mode #1 VI/II.
•Program Fundamentals Standard Mode Selection Command
Mode Use Terminal Board.
•Set VI/II Speed Reference #1 (F201) — the input signal level that
represents VI/II Torque Reference Setpoint #1.
•Set VI/II Torque Reference Setpoint #1 (F205).
•Set VI/II Speed Reference #2 (F203) — the input signal level that
represents VI/II Torque Reference Setpoint #2.
•Set VI/II Torque Reference Setpoint #2 (F206).
•Provide a Run command (F and/or R).
Once set, as the VI input voltage or the II current changes, the output torque of
the ASD will vary in accordance with the above settings.
This parameter sets VI/II Speed Reference #1 and is the input signal level that
is associated with the setting of VI/II Torque Reference Setpoint #1 while
operating in the Torque Control mode.
Direct Access Number — F201
Parameter Type — Numerical
Factory Default — 20.0
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 100.0
Units — %
Frequency Settings
Note: The default value for parameter
F201 is 20%. The II input is
commonly used for the 4 – 20 mA
current loop signal where 4 mA
equals 20% of a 20 mA signal. If
the VI input is used (0 – 10 VDC
input), this parameter may be
changed to 0.0% (of the input
signal).
Note: The speed control response may be
further trimmed by adjusting the
Bias and Gain settings.
