nMainSetValue_a
INT
C00700/1
Main speed setpoint
• Scaling: 16384 ≡ 100 % reference speed ( C00011 )
• 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_1 .

INT
C00700/2...3
Torque limitation in motor mode and in generator mode
• These input signals are directly transferred to the motor control to limit the
controller'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
wDriveControl
WORD
Control word via communication interface
• In the control mode "40: Network (MCI/CAN)", the controller controlled by a
master control (e.g. IPC) receives its control word via the communication
interface (MCI/CAN). The process data word is provided at this input by the
upstream port block LP_Network_In .
• See the " wDriveControl control word " subchapter for a detailed description of the
individual control bits.
bCInh
BOOL
C00701/1
Enable/Inhibit controller
FALSE Enable controller: The controller switches to the " OperationEnabled "
device status if no other source for controller inhibit is active.
• C00158 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 status.
