5. Type R Interface <br />

<br />

Each setting is enabled or disabled based on the type of zero-return.<br />

Zero-return type Velocity Low - velocity Grid shift Current limit Preset value<br />

C-channel detection Disabled Enabled Enabled Disabled Enabled<br />

SDN detection Enabled Enabled Enabled Disabled Enabled<br />

SDNC channel Enabled Enabled Enabled Disabled Enabled<br />

Push zero detection Enabled Enabled Enabled Enabled Enabled<br />

PushC channel detection Enabled Enabled Enabled Enabled Enabled<br />

Zero-return operation overview<br />

The zero-return in-position signal is output after the zero-return operation is complete.<br />

<br />

C-phase detection modeType <br />

Zero-return is based on detecting the C-phase (1 Pulse / rotation) of the motor-sensor.<br />

Grid shift travel distance<br />

Operation (velocity waveform)<br />

In-Position signal<br />

C-channel signal<br />

If high velocity is used, an overshoot can occur after detecting the C-phase, causing a<br />

return operation to be performed.<br />

2SDN detectionType 1<br />

Zero-return is performed by detecting the edge of the SDN signal connected to Pin 9 of CN1.<br />
