Torque Control: Sequence Input Signal (Reference Value - ) - Fuji Electric ALPHA7 User Manual

Torque control: Sequence input signal (Reference value - )

This signal is enabled only for VS type.
 Function
The torque control is executed by setting a value in data area after turning the "torque control" and
"forward or reverse command" on in IQ area.
 Relevant description
(1) Maximum rotation speed
If there is no load connected to the servomotor, the rotation speed is subject to a limitation on
PA1_26 (maximum rotation speed (for torque control)) with a variation of about ±100 [r/min] (due to
lack of speed control).
If PA2_56 (speed limit selection at torque control) is set to "2" (IQ area), the limit speed follows the
setting in IQ area.
(2) Torque setting filter
A filter can be performed by the setting of PA1_60.
(3) Output torque
The output torque of the servomotor has individual differences (variation) of about 0 to +5 [%]
under torque control. Continuous operation can be made if the output torque is within the rated
torque.
(4) Torque limit
Refer to "Torque limit 0: Sequence input signal (Reference value 19), Torque limit 1: Sequence
input signal (Reference value 20)" for torque limiting.
