6. Support of dv1 [Z Pulse Fault] in A1-02 = 3 [Control Method Selection = Closed
Loop Vector (CLV)]
Also, when A1-02 = 3 [Control Method Selection = Closed Loop Vector (CLV)], dv1 [Z Pulse Fault], errors can now be
detected.
With Closed Loop Vector, the Z phase is not used for normal control. However, when the Z-phase pulse signal must
be used to monitor the motor position on a host controller, for example, enable this function for protection.
■Added parameter
Sets the function to enable and disable dv1 detection.
When A1-02 = 7 [Control Method Selection = PM Closed Loop Vector
(CLV/PM)], the function is enabled at all times.
0: Disabled
