(1) Inverter settings are not ap-
propriate.
Confirm that the motor, and the
presence/absence and type of
speed/magnetic pole position
sensor
, are consistent with the
settings of
1st Drive control
selection (3004-2B hex),
Terminal [PIA][PIB] Pulse input
format (3014-0F hex), and
Terminal [PIA][PIB] Encoder
pulse resolution (3014-10 hex).
→ Confirm the machine configu-
ration (the motor, and the type
and specifications of and speed/
magnetic pole position sensor)
and correctly set 1st Drive
control selection (3004-2B
hex), Terminal [PIA][PIB] Pulse
input format (3014-0F hex), and
Terminal [PIA][PIB] Encoder
pulse resolution (3014-10 hex).
Check if 1st PM motor drive
magnetic pole position
detection mode (3007-1F hex)
is set to 0 or 3 and 1st PM
motor magnetic pole position
sensor offset (3007-60 hex) is
not 999 (Offset not adjusted).
→ Correctly set the 1st PM
motor magnetic pole position
sensor offset (3007-60 hex).
(Auto-tuning is also possible. Re-
fer to 7-8-1 Motor Off-line Auto-
tuning on page 7-65.)
Wire and set up the inverter ap-
propriately.
