3.4.4 Torque Control
The shaft output torque is controlled under the torque control according to torque command voltage
input [TREF] of the servo amplifier or a parameter setting.
If parameter PA1_01 is set at "2," the torque control mode starts after the RDY signal is turned on.
The torque is output while the manual forward command [FWD] or manual reverse command [REV]
signal is turned on, while the torque is reduced to zero after the signal is turned off.
Use parameter PA1_60 to specify the torque setting filter.
The maximum motor rotation speed can be controlled.


The speeds corresponding to multi-step speed selection (X3, X2 and X1) are given with
PA1_41 to PA1_47, or [VREF] terminal.
 Because the speed control is not performed, the actual speed limit level is different.
