nMainSetValue_a

INT

C700/1

Main speed setpoint

• Scaling: 16384 ≡ 100 % reference speed (

C011

)

• The main setpoint is transformed to a speed setpoint in the setpoint encoder via

a ramp function generator with linear or S-shaped ramps.

• Upstream to the ramp function generator, a blocking speed masking function

and a setpoint MinMax limitation are effective.

• For a detailed functional description see FB

L_NSet

.

Torque limitation in motor mode and in generator mode

• These input signals are directly transferred to the motor control to limit the con-

troller's maximum torque in motor and generator mode.

• The drive cannot output a higher torque in motor/generator mode than set here.

• The applied values (any polarity) are internally interpreted as absolute values.

• If sensorless vector control (SLVC) is selected, the limitation has a direct effect on

the torque-producing current component.

• Scaling: 16384 ≡ 100 % M

Device control
wCANControl

WORD

Control word via system bus (CAN)

• In the control mode "30: CAN", the controller controlled by a master control (e.g.

IPC) receives its control word by the CANopen system bus interface. The process

data word is provided at this input by the upstream port block

LP_CanIn1

.

• See the "

Process data assignment for control via CAN

" subchapter for a detailed

description of the individual control bits.

• Display parameter:

C136/2

bCInh

BOOL

C701/1

Enable/Inhibit controller

FALSE Enable controller: The controller switches to the "

OperationEnabled

"

device state, if no other source of a controller inhibit is active.

C158

provides a bit coded representation of all active sources/

triggers of a controller inhibit.

TRUE Inhibit controller (controller inhibit): The controller switches to the

"

SwitchedON

" device state.
