nTorqueMotLim_a
nTorqueGenLim_a
INT
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 V/f characteristic control (VFCplus) is selected, limitation is indirectly
performed via a so-called I
max
controller.
• If sensorless vector control (SLVC) is selected, the limitation has a direct effect on
the torque-producing current component.
• Scaling: 16384
≡
100 % M
max
(
C00057
)
Torque limits in motor and generator mode:
bSetSpeedCcw
BOOL
Change of direction of rotation
• For instance if a motor or gearbox is fixed laterally reversed to a machine part, but
the setpoint selection should still be executed for the positive direction of
rotation.
FALSE Direction of rotation to the right (Cw)
TRUE Direction of rotation to the left (Ccw)
bRLQCw
BOOL
Activate clockwise rotation (fail-safe)
• For a detailed functional description see the
L_RLQ
FB.
FALSE Quick stop
TRUE Clockwise rotation
bRLQCcw
BOOL
Activate counter-clockwise rotation (fail-safe)
• For a detailed functional description see the
L_RLQ
FB.
FALSE Quick stop
TRUE Counter-clockwise rotation
nMainSetValue_a
INT
Main speed setpoint
• Offset and gain of this input signal can be set in
C00696
and
C00670
for a simple
signal adjustment of a setpoint encoder.
• 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 the
L_NSet
FB.
nAuxSetValue_a
INT
Additional speed setpoint
• Offset and gain of this input signal can be set in
C00697
and
C00671
for a simple
signal adjustment of a setpoint encoder.
• Scaling: 16384
≡
100 % reference speed (
C00011
)
• The additional speed setpoint can be linked arithmetically with the main speed
setpoint behind the ramp function generator.
• The additional speed setpoint can be shown via ramp times of a second ramp
function generator.
• For a detailed functional description see the
L_NSet
