The torque limit value will be effective when the input signal is ON.
Forward external torque limit
The unit is the percent of motor rated torque; the default value is 100%.
Notes: /P-CL, /N-CL can be distributed to input terminal by parameter P5-15, P5-16. Refer to chapter
5-12-1.
Function realization:
5-5-7-3. External torque limit (via analog voltage command)
T-REF terminal is used as analog voltage command terminal. Please note in external
analog torque control mode, this function cannot be used.
Distribute function to
T-REF
Make T-REF as external
torque limit input
1. For analog voltage command input of torque limit. Get the absolute value of the voltage, the torque
limit value based on the absolute value is suitable for forward and reverse direction.
2. When it is used as torque limit, the value is related to voltage command and P4-00. For example,
P4-00=1000, T-REF voltage command is 5.0V, the torque limit value is 50% of rated torque.
5-5-7-4. External torque limit (via external input + analog voltage)
External torque limit via external input and analog voltage can be used together.
Input analog voltage signal from T-REF. the torque limit function cannot be used when
servo is in analog command torque control mode.
Use /P-CL and /N-CL signal when limit torque via external input.
(1) Parameters
T-REF function
distribution
When P-CL, N-CL is ON,
make T-REF as external
torque limit input.
Forward external torque limit OFF
Forward external torque limit ON
Min value between P4-02 and P4-04
Reverse external torque limit OFF
Reverse external torque limit ON
Min value between P4-03 and P4-05
Forward external torque limit
