Note) If the value set with  (stall prevention level) is smaller than the torque limit, then the value set
with  acts as the torque limit.
b) Limiting the torque with external signals
The torque limits can be changed arbitrarily by means of external signals.
[External signals]
Voltage signals
Current signals
With these parameters, you can set 4 patterns of positive torque limits and 4 patterns of
negative torque limits. Refer to 7.2 for the setting for switching from the terminal board.
