Operation transition
• If the setting value of Pr.7 and Pr.8 is "0", turning OFF the start signal enables speed control, and the output torque is
controlled by the torque limit value.
Item Description
Start signal
External operation STF, STR signal
PU operation
or on the operation panel or FR-PU07.
Torque command Selects the torque command input method and inputs the torque command.
Speed limit Selects the speed limit input method and inputs a speed limit value.
Torque control
Speed limit
Speed limit value is
increased up to preset value
according to the Pr.7
Acceleration time setting.
Speed limit value
Speed limit value is decreased
down to zero according to the Pr.8
Deceleration time setting.
Speed
Start signal
Output torque
Speed limit
Output torque is provided
according to the terminal 1
setting.
Speed control is peformed during speed
limit. (Thus, torque according to the
commanded is not developed.)
