3. SIGNALS AND WIRING
(3) External torque limit selection (TL), internal torque limit selection (TL2)
To use the external torque limit selection (TL) and internal torque limit selection (TL2), make them
available using the Servo Configuration Software (refer to Chapter 6).
These input signals may be used to choose the torque limit values made valid.

(4) External torque limit offset (parameter No.26)
Using parameter No.26, the offset voltage can be set relative to the input voltage of the analog torque
limit (TLA). The setting is between
999 to 999mV.
(5) Selection of rotation direction for torque limit execution (parameter No.59)
Using parameter No.59, the rotation direction for torque limit execution can be selected.
Rotation direction for torque limit execution
Parameter No.59 setting
CCW direction CW direction
0 (initial value)
1
2
For example, when “ 1 ” is set in parameter No.59, torque limit is executed in the CCW direction
but not in CW direction.
CCW rotation: Torque limit is executed.
CW rotation: Torque limit is not executed.
