6.11 Selecting Torque Limits
6.11.4 Limiting Torque with an External Torque Limit and an Analog Voltage Reference
/P-CL (Forward External Torque Limit) Signal, /N-CL
(Reverse External Torque Limit) Signal, and T-REF (Torque
Reference Input) Signal

Setting the Torque Limit with the External Torque Limit and
an Analog Voltage Reference
To limit the torque with an external input signal and an analog voltage reference, you must set
Pn002 to n.3 (Use T-REF or /N_CL as the torque limit when /P_CL or /N_CL is active).

log reference or the setting of Pn403 or Pn405.
Cancels the reverse external torque limit.
OFF (open)
The torque is limited to the setting of Pn403.
Applies the forward external force limit.
ON (closed) The force is limited to the smallest of the analog
reference or the setting of Pn483 or Pn404.
Cancels the forward external force limit.
OFF (open)
The force is limited to the setting of Pn483.
Applies the reverse external force limit.
ON (closed) The force is limited to the smallest of the analog
reference or the setting of Pn484 or Pn405.
Cancels the reverse external force limit.
OFF (open)
The force is limited to the setting of Pn484.
