4. 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
".
( 375)
• The preconfigured I/O connection in the selected control mode can be changed via
configuration parameters. See chapter "User-defined terminal assignment
". ( 365)

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.
L_NSet_1
( 1434)
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
( 107)
Fixed setpoint 1
(C00039/1
)
40.00 % A fixed setpoint for the setpoint generator can be
activated instead of the main setpoint via the digital DI1
and DI2 inputs.
• Fixed setpoints are selected in [%] based on the
reference speed (C00011
).

Fixed setpoint 2
(C00039/2
)
60.00 %
Fixed setpoint 3
(C00039/3
)
