Sampling Circuit
The AC gear of the multimeter
measures the input value of the
servo LN (R/S/T), which is 220V ±
10% of the normal value. If < 220V
+ 10% (380V + 10%), then check
the supply voltage; if the supply
voltage is normal, then servo BB
state, monitoring U0-05, multimeter
measurement voltage * 1.414 > U0-
05 (error within 10V), then the
servo driver is faulty and needs to
be sent back for repair.
