8.10.4 Limiting torque with external torque limit and analog command
The external input signals (P-CL and N-CL signals) and analog command (T-REF+ and T-REF- signals)
can be used for limiting torque at the same time. When forward external torque limit input (P-CL) signal or
reverse external torque limit input (N-CL) signal is ON, the smallest value of internal torque limit, external
toque limit and analog command is used as torque limit value. When P-CL or N-CL signal is OFF, only
internal torque limit will be used.
Note:
While limiting torque with analog command, the analog command is input via the pins for torque command input
signals, so this function cannot be used in torque mode.
Figure8.10.4.1
Forward external torque limit input (P-CL) signal, reverse external torque limit input (N-CL) signal and
analog command (T-REF+ and T-REF- signals) are described as below.
