Example of a torque single trigger run:
Table 5-11 Torque Single Trigger Run Example
Steps Item Operations
1
Terminal assignment
and wiring
Let Pn604=0x0014 (terminal X4 is the torque trigger terminal, and the trigger signal is given
externally); connect the trigger input signal according to the wiring of the cis-control input circuit,
CN1-40.
2 Control mode selection
Pn000.X = 2 (control mode selected as torque control).
Pn400.X = 4 (selection of the torque source as single trigger mode).
Pn400.Y=2 (speed limit is Pn415 when torque control is selected).
Pn430.X=1 (select trigger mode as rising trigger).
3 Servo Enable
Pn410 = 10 (arrival torque of 50%).
Pn415 = 200 (speed limit of 200 rpm for torque control).
When servo is enabled, the servo motor does not move.
4 Terminal Trigger
To close and then break terminal X4, i.e. rising edge trigger torque operation.
(a) Under no load, the speed rises to a limiting speed of 200 rpm and then runs at a constant
speed with a motor torque of about 5% and remains constant.
The load is then increased and when the load reaches 10%, the motor stops immediately and
waits for the next trigger.

Steps Item Operations
1
Control mode
selection
Pn000.X = 2 (control mode selected as torque control).
Pn400.X = 0 (the source of torque is selected as Pn410).
Pn400.Y=2 (speed limit is Pn415 when torque control is selected).
2 Torque setting Pn410=0, enable servo, servo motor does not move.
3 speed limit Pn415 = 1000 (i.e., speed limit of 1000 rpm for torque control).
4 Servo Enable Pn001.X=1.
5
Torque
adjustment
Pn410=20, motor speed up to 1000rpm at no load.
