RS terminal
When an alarm has tripped, setting the SON
signal to OFF and this RS signal to ON clears
the tripped alarm state, and operation can
resume.
FC-01 : Input terminal polarity setting
Related parameters
• If no alarm has tripped, this signal is ignored even if set to ON.
• When an alarm has tripped and then this signal is switched from OFF to ON, the
alarm trip state is canceled if the ON state lasts more than 20ms.
• Even if this signal remains at the ON state, reset operation is performed only once.
• By changing the "Input terminal polarity" (FC-01) setting, alarms can also be reset
when this input terminal is opened.
• The RS terminal might not always be able to cancel a tripped state, due to the
problem that triggered the alarm. See "9.3 Troubleshooting".
TL terminal
Setting this terminal to ON enables torque
limit. Use the parameters Fb-07 through Fb-10
to determine the torque limit values.
FA-00 : Control mode
FA-17 : Torque limit mode
Fb-07 to 10 : Torque limit value 1 to 4
FC-01 : Input terminal polarity setting
Related parameters
• By changing the "Input terminal polarity" (FC-01) setting, torque limit can also be
enabled when this input terminal is opened.
• The parameters Fb-07 through Fb-10 limit the torque in each quadrant as shown in
the figure below. (However, use the absolute value as the torque limit value when
entering the parameters.)
