The bit B0 controls the search direction. When you set the bit to 0, the shaft frequency is
searched in 2 directions, the positive and the negative. When you set the bit to 1, the shaft
frequency is searched only in the frequency reference direction. This prevents the shaft
movements for the other direction.
The bit 6 gives an enhanced procedure to magnetise an induction motor. It can help, for
example, with high power motors.
P3.1.2.20 I/F START (ID 534)
Use this parameter to enable the I/f Start function.
This function starts the motor with constant current control. It provides a sufficient torque
for the motor at startup. You can use this function for example with PM-motors.
P3.1.2.21 I/F START FREQUENCY (ID 535)
Use this parameter to set the output frequency limit below which the set I/f start current is
fed to motor.
When the output frequency of the drive is below the limit of this parameter, I/f Start function
activates. When the output frequency is more than the limit, the drive operation mode
changes back to the normal U/f control mode.
P3.1.2.22 I/F START CURRENT (ID 536)
Use this parameter to set the current that is used when the I/f Start function is enabled.
10.2
START/STOP SETUP
P3.2.1 REMOTE CONTROL PLACE (ID 172)
Use this parameter to select the remote control place (start/stop).
Use this parameter to change back to remote control from Vacon Live, for example if the
control panel is broken.
P3.2.2 LOCAL/REMOTE (ID 211)
Use this parameter to switch between the local and remote control places.
Local control place is always keypad control. The remote control place can be I/O or
Fieldbus, depending on the 'Remote Control Place' parameter value.
P3.2.3 KEYPAD STOP BUTTON (ID 114)
Use this parameter to enable the keypad stop button.
When this function is enabled, a press of keypad stop button always stops the drive
(regardless of the control place). When this function is disabled, a press of keypad stop
button stops the drive in local control only.
