dnMotorRefOffset_p
DINT
Home position in [increments]
• Value is adopted when control bit 9 ("HomeSetPos") is set from "0" to "1" in the
and is sent to the motor control function via the
dnMotorRefOffset_p_ output.
• Transfer is possible in any operating mode ("Homing on the fly").
• For this function, the two outputs bMotorRefOffsetOn_ and
dnMotorRefOffset_p_ must be connected to the inputs of the same name of
the
system block.
bQspOn
BOOL
Trigger quick stop (QSP) via the MCK
• 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).
• A pulse inhibit is set if the auto-DCB function has been activated
via
.
•
The motor is kept at a standstill during closed-loop operation
(function in preparation).
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.
nPWMAngleOffset
INT
Angular offset input
• Scaling: 16384 ≡ 100 %
• Setting range: 0 ... 199.99 %
bSpeedCtrlIOn
BOOL
Directly set the I-component of speed controller
• In order to statically specify a minimum torque, e.g. when a load is being lifted.
TRUE Se the I-component of the speed controller to the value
nSpeedCtrlI_a.
nSpeedCtrlI_a
INT
I-component of the speed controller
• Value is adopted in the case of a FALSE-TRUE edge at the input bSpeedCtrlIOn.
nSpeedSetValue_a
INT
Rotation speed/velocity setpoint
bTorquemodeOn
BOOL
TRUE Switch on torque-controlled operation
nTorqueSetValue_a
INT
Torque setpoint
bDcBrakeOn
BOOL
Manual DC-injection braking (DCB)
• For this function, the bDcBrakeOn_ output signal must be connected to the
bDcBrakeOn input of the same name of the
system block.
• 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
