Use the following table when contact input speed control is used.
Note: 1.
0: OFF (high level); 1: ON (low level)
2.
Input signals indicated by the horizontal bar (-) are optional.
•
When contact input speed control is not used, input signals are used as external
torque limit inputs.
Note: The contact input speed control function is used only when signals are allocated to /SPD-D, /SPD-A,
and /SPD–B.
Direction of Rotation Selection
The input signal /P-CON(/SPD-D) is used to specify the direction of servomotor
rotation.
•
When contact input speed control is used, the input signal /P-CON (/SPD-D)
specifies the direction of Servomotor rotation.
Note: 0: OFF (high level); 1: ON (low level)
•
When contact input speed control is not used, the /P-CON signal is used for pro-
portional control, zero clamping, and torque/speed control switching.
