VI/II Reference Point 1
Program Torque Setpoints
Program Frequency Speed Reference Setpoints
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.
This parameter sets the VI/II level that is associated with the VI/II Point 1
Frequency setting when operating in the Speed control mode or is associated
with the VI/II Point 1 Torque setting when operating in the Torque Control
mode.
The bias and gain of the VI/II terminal may be trimmed at
respectively.
VI/II Speed Control Setup
Perform the following setup to allow the system to receive control input at the
VI/II terminals:
•
Connect the input control current or voltage to the II input or the VI
input, respectively.
Program Fundamental Standard Mode Selection Frequency
•
Mode 1 VI/II
Program Fundamental Standard Mode Selection Command
•
Mode Selection Terminal Board
•
Set VI/II Point 1 Frequency (F202).
•
Set VI/II Reference Point 1 (F201) — the input analog signal level
that corresponds to the frequency setting at VI/II Point 1 Frequency.
•
Set VI/II Point 2 Frequency (F204).
•
Set VI/II Reference Point 2 (F203) — the input analog signal level
that corresponds to the frequency setting at VI/II Point 2 Frequency.
•
Provide a Run command (F and/or R).
Once set, as the VI/II input changes, the output frequency of the drive will vary
in accordance with the above settings.
This parameter value is entered as 0 – 100% of the VI/II input signal range.
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),
F201
may be changed to 0.0% (of the input signal).
Note:
When using the isolated VI/II terminal, the IICC terminal must
be used as the return (negative) connection.
VI/II Point 1 Frequency
Program Frequency Speed Reference Setpoints
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 mode.
See VI/II Reference Point 1
This parameter sets VI/II Point 1 Frequency and is the frequency that is
associated with the setting of VI/II Reference Point 1 (F201).
