Hall Sensor Phase Sequence Checking; Position Signal Converter Box - Delta ASDA-A3 Series User Manual

ASDA-A3 Linear Motor

11.4.1 Hall sensor phase sequence checking

To check the phase sequence of the Hall sensor, set P0.017 to -177 to set the monitoring
variable and observe the phase sequence change with P0.009. The bits of this monitoring
11
variable are (bit3, bit2, bit1) = (W, V, U). The following figure shows the waveform monitored by
the scope when you manually move the linear motor. You can see the phase sequence in the
cycle of ( 1, 0, 1), (1, 0, 0), (1, 1, 0), (0, 1, 0), (0, 1, 1), and (0, 0, 1). Incorrect phase sequence
may cause the motor to go in the wrong direction or even out of control.
Note: bit value of the monitoring variable -177:
Bit 1: U phase; Bit 2: V phase; Bit 3: W phase.

11.5 Position signal converter box

The position signal converter box is a feedback signal conversion product developed by Delta.
*
The feedback signals of OA/OB pulses or sine wave can be converted into Delta's
communication format without external power supply. Then the feedback signal is returned to
the servo drive through CN2. The position signal converter box increases the resolution and
avoids the frequency limit with the interpolation sine wave signal.
Note: this feature is not released yet.
