5-2-6 Limiting Servomotor Speed during Torque Control
In torque control, input contacts SPD1 and SPD2 can be used for selecting one of the two
methods below for setting speed limits.
(1) External Analog command ( Default) Signal is applied to terminals PIC & AG ( pins 27& 29 on CN1)
(2) Selection of Three presentable Limits (Tn105~Tn107) according to the table below.
Caution! For achieving smooth speed response please refer to section 5-3-6.

Internal presentable speed limit parameters for torque control mode are listed below:
These preset limits apply to both CW & CCW directions.
Parameter Name Default Unit Setting range Control mode
Tn105 Internal speed limit 1 100 rpm 0~3000 T
Tn106 Internal speed limit 2 200 rpm 0~3000 T
Tn107 Internal speed limit 3 300 rpm 0~3000 T
