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. 33
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:

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.
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
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
changed to 0.0% (of the input signal).
