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 "
• The preconfigured I/O connection in the selected control mode can be changed via
configuration parameters. See chapter "
User-defined terminal assignment
• 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,

Info
Value Unit
Accel. time - main setpoint
(
)
2.0 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 FB
!
Decel. time - main setpoint
(
)
2.0 s
Reference speed
(
)
1500 rpm
All speed setpoint selections are provided in % and
always refer to the reference speed set in
.
The motor reference speed is indicated on the motor
nameplate.
Decel. time - quick stop
(
)
5.0 s
If quick stop is requested, motor control is decoupled
from the setpoint selection and, within the deceleration
time parameterised in
, the motor is brought to
a standstill (n
act
= 0).

Fixed setpoints are selected in [%] based on the
reference speed (
).
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.
