bSetQuickstop
BOOL
Enable quick stop (QSP)
• Also see device command "Activate/Deactivate quick stop
".
TRUE Activate quick stop
• 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).
• The motor is kept at a standstill during closed-loop operation.
• A pulse inhibit (CINH) is set if the auto-DCB function has been
activated via C00019
.
FALSE Deactivate quick stop
• The quick stop is deactivated if no other source for the quick stop
is active.
• C00159
displays a bit code of active sources/causes for the quick
stop.
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) or servo control (SC) is selected, limitation has
a direct
effect on the torque-producing current component.
• Scaling: 16384 ≡ 100 % M
max
(C00057)
Note:
Setting this input is ineffective in the reference modes 14 and 15 ("Homing to
positive stop").
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)
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 % rated 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
