(Open Loop Vector Control Mode)
D To use the external winding change method, set the multi-function digital input used for receiving the
winding change signal to “80.” This setting enables the selection of Motor 1 constants (E1 and E2)
when the input is open and Motor 2 constants (E4 and E5) when the input is closed.
D When using the external winding change method, Auto-Winding constants (P1-01 and P1-02) are not
valid.
J Auto-Winding Change Method
This method can be used when the multi-function digital input is not set to “80.”
The selection of the motor 1 and motor 2 is conducted internally by preset constants, such as winding
change frequency (P1-01) and winding change hysteresis ( P1-02).
Winding change frequency: P1-01
