Magnetic Pole Position Estimation Force Command Time
3922 hex
Setting range 0 to 200
Size 2 bytes (INT16)
• Set the command application time for a single force command during magnetic pole position
estimation.
• If the number of motor movement pulses reaches the value set in the Magnetic Pole Position
Estimation Maximum Movement (3924 hex) or a larger value, the force command will stop even
before the force application time expires.
• This setting is enabled only when the Magnetic Pole Detection Method (3920 hex) is set to 2
(Magnetic pole position estimation method).
Precautions for Correct Use Precautions for Correct Use
• If this object is set to a small value, the motor may not show its full performance, resulting in a
poor detection accuracy or a Magnetic Pole Position Estimation Error. If the motor is subjected
to a large load or resistance, set a sufficiently long force command time.
• The magnetic pole position estimation accuracy may be improved by increasing the set value
in the Magnetic Pole Position Estimation Force Command Time (3922 hex) or Magnetic Pole
Position Estimation Force Command (3923 hex). However, if you set a large value in the
Magnetic Pole Position Estimation Force Command Time (3922 hex), an Overload Error (Error
No. 16.0) will occur depending on the Magnetic Pole Position Estimation Force Command
(3923 hex) setting.
• The actual command time will be approx. the set value plus 4 ms.
