[4] Diagnosis and remedy
When the diagnosis signal bit on [PLG diagn] is "1", check the installation of the PLG encoder again.
<When the waveform of spindle side PLG installation gap diagnosis is abnormal>
The gap between the sensor section and the gear may deviate from the specified value. Confirm that the
sensor section is installed on the notched fitting section properly. Also confirm that the notched fitting section is
machined properly based on the specified dimensions for each PLG encoder.
<When the waveform of spindle side PLG installation all errors diagnosis is abnormal>
The sensor section may deviate from the center of the gear. Confirm the installation of the sensor section and
the gear.
CAUTION
1. When finely adjusting the sensor installation position, adjust after turning the power of the drive unit OFF.
2. "00000000" is also displayed in the following cases.
(1) When the spindle parameter #13018/bit1(SP018/bit1) is 0 (open loop disabled)
(2) When an encoder other than TS5690 Series is connected
