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
, the motor
is brought to a standstill (n
act
= 0).
• The motor is kept at a standstill during closed-loop operation.
• A pulse inhibit is set if the auto-DCB function has been activated
via
.
FALSE Deactivate quick stop
• The quick stop is deactivated if no other source for the quick stop
is active.
•
displays a bit code of active sources/causes for the quick
stop.
bSetDCBrake
BOOL
Manual DC-injection braking (DCB)
• Detailed information on DC-injection braking is provided in the motor control
chapter, subchapter "
Note!
Holding braking is not possible when this braking mode is used!
Use the basic "
" function for controlling the holding brake with
a low rate of wear.
FALSE Deactivate DC-injection braking.
TRUE Activate DC-injection braking, i.e. the drive is brought to a standstill
by means of DC-injection braking.
• The braking effect stops when the rotor is at standstill.
) has expired, the controller sets the
pulse inhibit.
bRFG_Stop
BOOL
Ramp function generator: Maintain the current value of the main setpoint
integrator
• The speed, for instance, of a running ramp process is immediately kept constant
when bRFG_Stop is activated. At the same time, the acceleration/deceleration
jumps to the value "0".
• For a detailed functional description see the
FB.
TRUE The current value of the main setpoint integrator is held.
bRFG_0
BOOL
Ramp function generator: Lead the main setpoint integrator to "0" within the
current Ti times
• In case of control via fieldbus (NetCtrl=1): If a stop is triggered via bit 0 ("Run
Forward") and bit 1 ("Run Backward") of the AC Drive Profile control word, this
signal is internally set to TRUE and thus the drive is braked to standstill.
• For a detailed functional description see the
FB.
TRUE The current value of the main setpoint integrator is led to "0" within
the Ti time set.
nVoltageAdd_a
INT
Additive voltage impression
• An additional setpoint for the motor voltage can be specified via this process
input.
• If there are, for instance, different loads at the motor output end, it is possible to
apply a voltage boost at the starting time.
• If the value is negative, the voltage is reduced.
• Scaling: 16384 ≡ 1000 V
Stop!
Values selected too high may cause the motor to heat up due to the resulting
current!
