• 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 UsePrecautions 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.

• Set the command force for a single force command during magnetic pole position estimation.
