・ Function of soft OT
When 1 is set at system para.75, the soft OT is able to operate on condition that the current position is bsoft OT and –soft OT
detection position (system para. 77 and 76 setting).
In case the current position goes out of range, stops the motor forcibly, a control output OT detection (20) is turned on. When the pulse
train input with opposite direction to the detection direction is input, or manual feed (forward command/reverse command) is input, and
the current position retruns to within the range, OT detection (20) is turned off, and it allows the mechanical equipment system to move in
both directions.
The soft OT function can be also valid after the origin return complete by basic para. 67 setting.
Basic parameter 67
Para. Name Setting range Initial value Change
67 Position detection valid/invalid 0: Effective after end of origin return, 1: Always 0 Always
*When the origin return action is completed or the position preset is executed, the origin return is completed.
5.5.4 Torque limit [TLMT], torque limit detection
This function limits the motor output torque.
Motor output torque can be limited while torque limit [TLMT] (30) signal is on.
Torque limit value can be set by basic para. 59, from 0 to maximum output torque in 1% steps.
Maximum output torque depends on motor type.
Maximum output torque is set assuming the rated torque is 100%.
Torque limit is always effective in any control condition.
If output torque is limited during acceleration or deceleration, acceleration or deceleration may not follow the accel./decel. time set by basic
para.
・
Torque limit detection
This signal is turned on while motor torque reaches the torque limit value.
This torque limit detection (26) is effective in all control condition.
