Torque command / torque limit via PROFIBUS communication (Pr.804) (only for
the FR-A800 series)
Setting
Pr.804 Torque command source selection
= "3 or 5" enables torque command / torque limit via PROFIBUS
communication under Real sensorless vector control, torque control under vector control, and speed control.
(When
Pr.804
"3 or 5", writing a torque command/limit value via PROFIBUS communication causes turning ON of Alarm 1 to
Alarm 7 corresponding to REF1 to REF7, resulting in generation of a command execution error.)
Can also be set from operation panel or parameter unit.
When used as a torque limit value, the value is an absolute value.
The priority of the torque limit value is as follows: TL signal > PROFIBUS communication >
Pr.810
.
