Magnetic Position Detection Completed Signal (PTD)
The ON signal is output when the magnetic pole position is detected at PM motor startup. This param-
eter is enabled when 3007Hex-1FHex is set to other than 0.

Synchronous Motor Magnetic Pole Position Pull-in Frequency
When using an encoder having A, B and Z phase outputs in PM Vector control with speed and pole
position sensor, pull-in operation at the magnetic pole position is performed at the frequency set at
3014Hex-51Hex during the period up to detection of the Z phase immediately after power is turned ON
as the magnetic pole position is unknown. After detection of the Z phase, the magnetic pole position
referenced to the magnetic pole position sensor of
fset set to 3007Hex-60Hex is established, and regu-
lar operation is switched to.
Generally, there is no need for adjustment.
