Torque Command Input 2 (TREF2) and Forward Torque Limit Input (PCL)
Pin 16: Torque command input 2 (TREF2) and forward torque limit input (PCL)
Pin 17: Analog input ground 2 (AGND2)
Function
 During position control, speed control or fully-closed control
This signal provides a forward torque limit input (set value: 0 or 4) or forward/reverse torque limit
input (set value: 5) according to the setting of Torque Limit Selection (Pn521).
You can use Analog Torque Limit Scale (Pn527) to change the torque limit scale relative to the
analog input.
 During torque control
This signal provides a torque command input (set value: 1) according to the setting of Torque
Command/Speed Limit Selection (Pn317).
In the case of torque command input 2 (TREF2), you can use Torque Command Scale (Pn319)
3
to change the rotation speed scale relative to the command input.
Reverse Torque Limit Input (NCL)
Pin 18: Reverse torque limit input (NCL)
Pin 17: Analog input ground 2 (AGND2)
Function
 During position control, speed control or fully-closed control
This signal provides a reverse torque limit input (set value: 0 or 4) according to the setting of
Torque Limit Selection (Pn521).
You can use Analog Torque Limit Scale (Pn527) to change the torque limit scale relative to the
analog input.
Operation command (RUN)
Pin 29: Operation command (RUN)
This is the allocation at default setting. You can change the logics and allocations for input
terminals (CN1 to 8, 9 and 26 to 33) according to the settings of Input Signal Selection 1 to 10
(Pn400 to 409).
You must always allocate the operation command (RUN). If it is not allocated, the servo will
not turn ON.
Function
This input turns ON the power drive circuit for the main circuit of the Servo Drive. If this signal
is not input (servo OFF), the motor cannot drive.
Forward Drive Prohibition Input (POT) and Reverse Drive Prohibition Input (NOT)
Pin 9: Forward drive prohibition input (POT)
Pin 8: Reverse drive prohibition input (NOT)
