VI/II Speed Reference Setpoint #1 (%)
Program ⇒ Frequency Setting Parameters ⇒ Speed Reference Setpoints ⇒ VI/II
This parameter is used to set the gain and bias of the VI/II input terminals when either terminal is used as the control input while operating in the Speed Control or the Torque Control mode.
Note: See note on pg. 46 for further information on the VI/II terminal.
Perform the following setup to allow the system to receive control input at the VI/II terminals:
•Program ⇒ Fundamental Parameters ⇒ Standard Mode Selection ⇒ Command Mode ⇒ Use Control Terminal Strip.
•Program ⇒ Fundamental Parameters ⇒ Standard Mode Selection ⇒ Frequency Mode #1 ⇒ Use VI/II.
•Provide a Run command (F or R).
Gain and Bias Settings
When operating in the Speed Control mode, the settings that determine the gain and bias of the VI/II terminals are:
•VI/II Speed Reference Setpoint #1 (frequency) (F202),
•the VI/II input signal level that represents VI/II Speed Reference Setpoint #1 (frequency): F201,
•VI/II Speed Reference Setpoint #2 (frequency) (F204), and
•the VI/II input signal level that represents VI/II Speed Reference Setpoint #2 (frequency): F203.
When operating in the Torque Control mode, the settings that determine the gain and bias of the VI/II terminals are:
•Torque Reference Setpoint #1 (%) (F205),
•the VI/II input signal level that represents the VI/II Torque Reference Setpoint #1 (%): F201,
•Torque Reference Setpoint #2 (%) (F206),
•the VI/II input signal level that represents Torque Reference Setpoint #2 (%): F203.

Frequency Settings
Torque Settings
Once set, as the VI/II input changes, the output frequency or the output torque of the drive will vary in accordance with the above settings.
This parameter sets the VI/II input level that represents VI/II Speed Reference
Setpoint #1 (torque or frequency). This value is entered as 0 – 100% of the
VI/II input signal range.
The input signal may be trimmed using F470 (Bias) and F471 (Gain).
The default value for this 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), parameter F201 may be changed to 0.0% (of the input signal).
