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

".

( 461)

• The preconfigured I/O connection in the selected control mode can be changed via

configuration parameters. See chapter "

User-defined terminal assignment

".

( 361)

• 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).

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 ( 106)

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 %
