P-27 f-Skip1 0.0 Hz Max Frequency Centre point of the frequency band defined by f-
Skip-Band1 in which the drive doesn’t work in
steady-state. 0.0 Hz
P-28 V-MidV/f 0 V P-07 Voltage to shape V/f curve
Defines the adjustment voltage at the frequency
set in P-29.
0 V
P-29 f-MidV/f 0 Hz P-09 Frequency to shape V/f curve
Sets the frequency at which the adjustment
voltage defined with P-28 is applied to the motor.
0 Hz
P-30 Start Mode 0 6 Defines the behaviour of the drive relating to the
enable digital input and also configures the
automatic restart function.
Edge-r : Following power on or reset, the drive will
not start if a start signal (FWD/REV) is still present.
To start DC1 a rising edge is necessary.
Auto-0 : Following a power on or reset, the drive
will automatically start if digital input 1 is closed.
Auto-1 to 5: Following a trip, the drive will make up
to 5 attempts to restart at 25 second intervals. The
drive must be powered down to reset the counter.
The number of restart attempts are counted, and if
the drive fails to start on the final attempt, the
drive will trip, and will require the user to manually
RESET the fault.
Notice:
An automatic restart is only possible when the
control commands are given via terminals
(P-12 = 0, P-12 = 11).
0
P-31 Digital Reference Reset
Mode 0 7 Defines the behavior of the drive on START when
used in Keypad control or when controlled with
UP/DOWN commands via terminals.
0: Start at min speed
1: Start with latest speed before switching off
2: Start at min speed (Auto-r)
3: Start with latest speed before switching off
(Auto-r)
4: Start with current running speed
5: Start with f-Fix4
6: Start with current running speed (Auto-r)
7: Start mit f-Fix4 (Auto-r)
Auto r: START and STOP button on the keypad are
disabled. The drive starts with a START command
at the terminals.
