Zero voltage time while start up
Settings
When the motor is in static status at the startup, the accuracy to estimate angles will be
increased. In order to make the motor in "static status", the drive 3 phase U, V, W output 0V to
motor to reach this goal. The Pr10-49 setting time is the length of time when three-phase output
0V.
It is possible that even when this parameter is being applied but the motor at the installation site
cannot go in to the "static status" caused by the inertia or by any external force. So, if the motor
doesn't go into a completer "static status" in 0.2 sec, increase appropriately this setting value.
This parameter is functional only when the setting of Pr07-12 Speed Search during Startup 0.
Reverse angle limit (Electrical angle)
Settings
While forward run is starting, if there is a sudden reverse run and the reverse angle is bigger
than the Pr10-50 setting, then, drive will has a ScRv error.
This parameter is valid only when Pr07-28 =11 Enable textile machine's function.
Injection Frequency
Settings
This parameter is a High Frequency Injection Command when the motor drive is under IPM HFI
sensor-less control mode and it doesn't often need to be adjusted. But, if a motor's rated
frequency (i.e. 400Hz) is too close to the frequency setting of this parameter (i.e. 500Hz), the
accuracy of angles detected will be affected. Therefore, refer to the setting of Pr01-01 before
adjusting this parameter.
