Fault Type(s):
1 Failure to determine encoder
pulses. Must be set manually.
72 Temp sensor fault.
73 Motor hot.
74 Controller temperature
cutback.
76 Undervoltage cutback.
77 Overvoltage cutback.
78 Encoder not reading
properly.
79 Current Regulator Tuning out
of range.
80 Current Regulator Tuning out
of range.
81 Encoder signal seen but step
size not auto-detected, it
must be set manually.
82 Aborted commissioning.
83 Sensor signal too noisy for
characterization.
84 Motor not rotating, Sin/Cos
sensor voltages out of
spec, or Multiturn Sensor
setting incorrect.
85 Sensor signal too noisy for
characterization.
Motor characterization failed during
characterization process. The fault
type indicates the cause.
Type 84:
During commissioning, if the Type
84 fault occurs, check that the
Sin/Cos signal voltages at their
maximums and minimums have
differences less than 78mV. (i.e.,
that |Sinmax Δ Cosmax| < 78mV
and the |Sinmin Δ Cosmin| < 78mV).
If the differences are greater than
78mV (e.g., 100mV), it will trigger
the Type 84 fault and abort the
motor characterization routine.
Types are also listed in Chapter 6,
Table 21.
Set: Motor characterization
failed during the motor
characterization process.
