This parameter selects the communications reference for scaling. | Changeable During Run — Yes | |
|
| |
See F811 — F814 for further information on this setting. |

|
Note: Scaling the communications signal is not required for all |

|
applications. |

Changes made to this parameter require that the power be cycled (Off then On) |

When enabled at F810, this parameter is used to allow the user to set the gain | Changeable During Run — Yes | |
|
| |
and bias of the speed control input to the drive when the speed control signal is | Minimum — 0.00 |
|
received via the source selected at F810. | Maximum — 100.0 |

Gain and Bias Settings | Units — % |
|
When operating in the Speed Control mode and using one of the control |
|
|
sources from Settings above, the settings that determine the gain and bias |
|
|
properties of the input signal are: |
|
|
• Communications Reference Speed Setpoint #1 (frequency)
(F812),
• the communications input signal value that represents Communications Reference Speed Setpoint #1 (frequency): F811,
• Communications Reference Speed Setpoint #2 (frequency)
(F814), and
•the communications input signal value that represents Communications Reference Speed Setpoint #2 (frequency): F813.
Once set, as the input signal value changes, the output frequency of the drive will vary in accordance with the above settings.
This parameter sets the Communications Reference input value that represents Communications Reference Speed Setpoint #1 (frequency). This value is entered as 0 to 100% of the Communications Reference input value range.
Changes made to this parameter require that the power be cycled (Off then On) for the changes to take effect.
