4.2.11 Torque Limiting by Analog Voltage Reference, Function 2
Torque limiting by analog voltage reference limits torque by assigning a torque limit in an
analog voltage to the T-REF terminal (CN1-9 and 10). It cannot be used for torque control
because the torque reference input terminal T-REF is used as an input terminal. If the /P-CL
signal (CN1-45) is ON, a forward torque limit is applied, and if the /N-CL signal (CN1-46)
is ON, a reverse torque limit is applied.
„ Using Torque Limiting by Analog Voltage Reference
To use this function, set the following parameter to 3.
This setting will enable torque limiting by analog voltage reference, function 2.
This torque limiting function cannot be used at the same time as the torque feed-forward
function.
