■
Alarm code 44 (Magnetic pole position estimation error)
 Magnetic pole position estimation operation failed.
Status at the time of alarm
Cause
1 2 3 4 5 6 7 8
Issued when control power supply is
turned ON.
✔
Issued during magnetic pole position
detection.
✔ ✔ ✔ ✔ ✔ ✔ ✔
 Corrective actions
Cause Investigation and corrective actions
1
■ Magnetic pole position detecting
frequency is same as mechanical
resonance.
■
Motor reaches to end of stroke.
■ Changing the Index 0x20F1-8 "Excitation
command frequency setting value".
■ Keep distance to end of stroke.
2
■
Load mass is too large.
■
Sizing a linear motor, again.
3
■
Force limitation command is too small.
■
Increase a set value of the
Index 0x20E0 "Forward Direction Force Limit
Value",
Index 0x20E1 "Reverse Direction Force Limit
Value".
4
■ Defect in internal circuit of servo
amplifier.
■
Replace the servo amplifier.
5
■
Wiring of U/V/W-phase between servo
amplifier and linear motor is wrong.
■
Check the wiring conditions and correct it if
improper.
6
■
Wiring of A/B-phase of linear encoder
is wrong.
■
Check the wiring conditions and correct it if
improper.
7
■ Linear encoder resolution setting is
wrong.
■ Set correct value to the Index 0x20FF-1
"Encoder resolution code [ENCODE]".
8
■ Operation direction of linear
encoder is wrong.
■ Set the Index 0x20F1-7 "Linear Encoder Polarity
Selection" correctly.
■
Alarm code 45 (Average continuous over speed)
 Over speed in average rotational speed
Status at the time of alarm
Cause
1
Occurred during operation.
✔
 Corrective actions
Cause Investigation and corrective actions
1
■ The average speed exceeds the
maximum speed of continuous rotation
speed range.
■
Review the operating conditions.
■ Resize the servo motor.
