Application Functions
/P-CL (Forward External Torque Limit) Signal, /N-CL
(Reverse External Torque Limit) Signal, and T-REF (Torque
Reference Input) Signal
The input signals that are used for torque limits with an external torque limit and an analog volt-
age reference are described below.
 T-REF (Torque Reference Input) Signal
 /P-CL (Forward External Torque Limit) Signal and /N-CL (Reverse
External Torque Limit) Signal
 /P-CL (Forward External Force Limit) Signal and /N-CL (Reverse Exter-
nal Force Limit) 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).
Typ e Signal Connector Pin No. Name
Input
T-REF CN1-9 Torque reference input
SG CN1-10 Signal ground for torque reference input
Typ e Signal Connector Pin No. Signal Status Meaning
Input /P-CL
CN1-45
(default setting)
ON (closed)
Applies the forward external torque limit.
The torque is limited to the smallest of the ana-
log reference or the setting of Pn402 or Pn404.
OFF (open)
Cancels the forward external torque limit.
The torque is limited to the setting of Pn402.
Input /N-CL
CN1-46
(default setting)
ON (closed)
Applies the reverse external torque limit.
The torque is limited to the smallest of the ana-
log reference or the setting of Pn403 or Pn405.
OFF (open)
Cancels the reverse external torque limit.
The torque is limited to the setting of Pn403.
Typ e Signal Connector Pin No. Signal Status Meaning
Input /P-CL

(default setting)
ON (closed)
Applies the forward external force limit.
The force is limited to the smallest of the analog
reference or the setting of Pn483 or Pn404.
OFF (open)
Cancels the forward external force limit.
The force is limited to the setting of Pn483.
Input /N-CL
CN1-46
(default setting)
ON (closed)
Applies the reverse external force limit.
The force is limited to the smallest of the analog
reference or the setting of Pn484 or Pn405.
OFF (open)
