APPLICATIONS OF Σ-SERIES PRODUCTS
3.2.6 Using Contact Input Speed Control
86
Input signal /P-CON is used to specify the direction of motor rotation.
→ Input /P-CON 1CN-41
Proportional Control, etc. For Speed/Torque
Control and
Position Control
When Contact Input Speed Control is used:
Use input signal /P-CON to specify the direction of motor rotation.
/P-CON Meaning
1 Reverse rotation
0 Forward rotation
0: OFF (high level), 1: ON (low level)
Modes Other Than Contact Input Speed Control
/P-CON signal is used for proportional control, zero-clamp and torque/speed control
changeover.
The figure below illustrates an example of operation in contact input speed control mode.
Using the soft start function reduces physical shock at speed changeover.
