If you want to slowly increase the size of Id, increase the filter time to avoid a Step phenomenon

occurs when starting current output. When decrease the filter time (minimum value is 0), the
current rises faster, then a Step phenomenon occurs.
Initial Angle Detection Pulse Value

Settings
 The angle detection is fixed to 3: Use the pulse injection method to start. The parameter
influences the value of the pulse during the angle detection. The larger the pulse, the higher the
accuracy of rotator's position. A larger pulse might cause oc.
 Increase the parameter when the running direction and the command are opposite during
start-up. If oc occurs at start-up, then decrease the parameter.
 Refer to Section 12-2 Adjustment & Application for detailed motor adjustment procedure.

Zero Voltage Time during Start-up

Settings
 This parameter is valid only when the setting of Pr. 07-12 (Speed Tracking during Start-up) = 0.
 When the motor is in static status at start-up, this increases the accuracy when estimating
angles. In order to put the motor in static state, set the three-phase drive output to 0 V to the
motor. The Pr. 10-49 setting time is the length of time when three-phase output at 0 V.
 It is possible that even when you apply this parameter, the motor cannot go into the static state
because of inertia or some external force. If the motor does not go into the static state in 0.2
seconds, increase this setting value appropriately.
 If Pr. 10-49 is too high, the start-up time is longer. If it is too low, then the braking performance is
weak.
Reverse Angle Limit (Electrical Angle)

Settings
 When the drive is running forward, if a sudden reverse run occurs and the reverse angle
exceeds the setting for Pr. 10-50, then a ScRv error occurs.
 This parameter is valid only when the setting of Pr. 07-28 =11 (enable textile machine).
 If the estimated tolerance of start-up angle detection is larger, and causes a reverse run of the
motor, this parameter can limit the reverse angle.
