3.1 CONFIRMATION WITH THE POSITION DETECTION
CIRCUIT
NOTE
The operation described below is required only
when an incremental linear encoder is used. The
operation described below is not required when an
absolute linear encoder is used.
Open the cover of the position detection circuit, and check the
waveform with the signal check lands placed on the periphery of the
printed circuit board.
Output to the CNC or separate detecto
interface unit (15-pin round connector)
Input from the scale (12-pin round connector)
, XA, B, XB, Z, XZ:
Signal from the scale
T1: Analog reference voltage
0°, 90°: Internal analog signal
0V, 5V: Power supply
PA, PB, PZ: Digital signal
Check the analog signal inside the circuit to check the waveform
output from the linear encoder.
