3. Adapt the application parameters:
 Tip!
•Click the Signal flow button to go down one dialog level to the signal flow of the
application with further possible parameter settings. See chapter "Basic signal flow
".
( 466)
• The preconfigured I/O connection in the selected control mode can be changed via
configuration parameters. See chapter "User-defined terminal assignment
". ( 365)
• Low-jerk traversing profiles can be implemented by means of S-shaped ramps.
• In the case of high breakaway torques combined with horizontal motion sequences,
"Sensorless vector control (SLVC)" can be used as motor control (C00006
).
• For reversal of rotation direction (bidirectional motion), comprehensive configuration
options are available in the inverter (e.g. by means of the L_DFlipFlop
function block).

Parameters Lenze setting Info
Value Unit
Accel. time - main setpoint
(C00012
)
2.000 s The setpoint is led via a ramp function generator with
linear characteristic. The ramp function generator
converts setpoint step-changes at the input into a ramp.
Note: These settings only apply if no other ramp times
have been selected at the L_NSet
FB!
Decel. time - main setpoint
(C00013
)
2.000 s
Reference speed
(C00011
)
1500 rpm All speed setpoint selections are provided in % and
always refer to the reference speed set in C00011
.
The motor reference speed is indicated on the motor
nameplate.
Decel. time - quick stop
(C00105
)
2.000 s If quick stop is requested, motor control is decoupled
from the setpoint selection and, within the deceleration
time parameterised in C00105
, the motor is brought to
a standstill (n
act
=0).
Activate/deactivate quick stop

Fixed setpoint 1
(C00039/1
)
40.00 % Fixed setpoints are selected in [%] based on the
reference speed (C00011
).
Fixed setpoint 2 must be smaller than fixed setpoint 3!
Otherwise, the drive will be started with a low speed
and accelerated after the pre-switch off.
Fixed setpoint 2
(C00039/2
)
60.00 %
Fixed setpoint 3
(C00039/3
)
80.00 %
