Preset values (0 or 1) and input signal status in the portions indicated by horizontal
bars (−) are optional.
Note When the contact input speed control function is used, the reference pulse inhibit
function is not available.
b) Standard Setting when Cn-02 bit 2 = 0
Input signals are used as external torque limit input.
Input signal P-CON is used to specify the direction of motor rotation.
→ Input P-CON 1CN-15
a) Contact Input Speed Control when Cn-02 bit 2 = 1
Use input signal P-CON to specify the direction of motor rotation.
P-CON
1 Reverse rotation
0 Forward rotation
0: OFF (high level), 1: ON (low level)
b) Standard Setting when Cn-02 bit 2 = 0
P-CON signal is used for proportional control, zero-clamp and torque/speed control
changeover.
Note For the speed/torque control type, control by external reference (voltage refer-
ence) is possible when the contact input speed control function is used by setting
bits A and B of user constant Cn-01.
For the position control type, control by external reference (pulse reference) is
possible when the contact input speed control function is used by setting bit F of
user constant Cn-01.
