Description Check point and remedy reference
Check presence and model of the used mo-
tor, and of the speed/magnetic pole position
sensor, and that 1st Drive Control Selection
(3004Hex-2BHex)/Input Terminal [PIA][PIB]
Pulse Input Format Selection
(3014Hex-0FHex) and Input Terminal [PIA]
[PIB] Encoder Pulse Resolution
(3014Hex-10Hex) are coordinated.
→ Check the equipment configuration
(model and specifications of motor,
speed/magnetic pole position sensor),
and set 3004Hex-2BHex/
3014Hex-0FHex/3014Hex-10Hex cor-
rectly.
Set the 1st PM Motor Starting Method
(3007Hex-1FHex) to 0 or 3, and check if the
1st PM Motor Magnetic Pole position Off-
set(3007Hex-60Hex*) is set to "999: Offset
not adjusted."
→ Set 3007Hex-60Hex correctly. (Auto-
tuning also is possible. Refer to Offline
Auto-tuning of Synchronous Motor (PM
Motor) on page 7-67.)
Check for errors with speed/magnetic pole
position sensor output wiring connection, and
the phase sequence of AB or UVW phase.
→ Correctly connect the feedback input
terminal block board with the speed/
magnetic pole position sensor.
Check for bad connections in the motor
wiring, and the phase sequence.
→ Ensure a correct connection with the in-
verter and motor.
Check if the terminal block board connector
and inverter unit connector are correctly con-
nected.
→ Mount the terminal block board correctly
in the inverter unit.
Check measures against noise (grounding
conditions, signal wiring and communication
cable/main circuit wiring and installation
methods, etc.).
→ Implement measures against noise.
