6. Torque Control
6.4 Torque command
• Torque commands given by analog inputs can be calibrated by the calibration parameters
C38 (Pr.932) to C41 (Pr.933)
Torque command given by parameter (Pr.804 = "1")
• Set
Pr.805 Torque command value (RAM)
or
Pr.806 Torque command value (RAM, EEPROM)
to set the torque
command value.
For
Pr.805
or
Pr.806
, regard 1000% as 0%, and set torque command by offset from 1000%.
The following diagram shows relation between the
Pr.805
or
Pr.806
setting and the actual torque command value.
• To change the torque command value frequently, write it in
Pr.805
. Writing values in
Pr.806
frequently will shorten the life
of the EEPROM.
NOTE
• When the torque command is set by
Pr.805
(RAM), powering OFF the inverter erases the changed parameter value.
Therefore, the parameter set value is the one saved by
Pr.806
(EEPROM) when the power is turned back on.
• If giving torque command by parameter setting, set the speed limit value properly to prevent overspeeding. (Refer to
Torque command via communication (Pr.804 = "3, 5, or 6")
• Set the torque command value via CC-Link (FR-A8NC / PLC function), CC-Link IE TSN, CC-Link IE Field Network Basic,
and PROFIBUS-DP (FR-A8NP) communication.
• For speed limit when "3 or 5" is set in
Pr.804
,
Pr.807 Speed limit selection
becomes invalid and
Pr.808 Speed limit
and
Pr.809 Reverse-side speed limit
become valid for speed limit. (When
Pr.544 CC-Link extended setting
= "0, 1, 12, 100,
or 112")
•
Pr.807
is valid when the extended cyclic setting of CC-Link communication is quadruple or octuple.
*1
They can also be set using the operation panel or parameter unit.
*2
When the FR-A8NP is installed, the torque command can be set only by
Pr.805
or
Pr.806
.
*3
On the operation panel or parameter unit, the setting range is "673 to 1327 (-327% to 327%)" and the setting increment is 1%.
