Frequency Point Selection
Program ⇒ Communications ⇒ Communication Reference Adjust
This parameter is used to set the communications reference for scaling.
See F811 — F814 for more information on this setting.
Note: Scaling the communications signal is not required for all applications.
Direct Access Number — F810
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — Yes
Changes made to this parameter require that the power be cycled (Off then On) for the changes to take effect.
Settings:
0 — Disabled
1 — RS485
2 — RS485
3 — Communication Card

and bias of the speed control input to the drive when the speed control signal is | |||

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. |

This parameter is used to set the gain and bias of the Communications
Reference speed control input.
Changeable During Run — Yes
See F811 for more information on this setting.
Minimum — 0.00
This parameter sets Communications Reference Speed Setpoint #1.
Maximum — Max. Freq. (F011)
Changes made to this parameter require that the power be cycled (Off then On) for the changes to take effect.
