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 ".
( 521)
• The preconfigured I/O connection in the selected control mode can be changed via
configuration parameters. See chapter " User-defined terminal assignment ". ( 421)
• 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 drive controller (e.g. by means of the L_DFlipFlop function
block).

Parameter 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 ( 108)
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 %
