Control words
MCK: wMotionCtrl1
wMotionCtrl2
WORD
MCK control word 1 & 2
• The two control words together form a 32-bit double control word with which
the entire Motion Control Kernel is controlled.
• All motion profiles in the different operating modes can be operated via this
interface.
• See the "
" subchapter for a detailed description of the
individual control bits.
• Display parameter:
wAuxCtrl
WORD
For future extensions - Input has no function at present time!
Additional control word
wSMCtrl
WORD
Interface to the optional safety system.
• Setting control bit 0 ("SafeStop1") in this control word causes e.g. the automatic
deceleration of the drive to standstill within this application (in the
Motion
Control Kernel
).
• See the "
" subchapter for a detailed description of the
individual control bits.
Control and setpoint signals for Motion Control Kernel function
dnProfilePosition_p
DINT
Profile position in [increments]
• Position which is to be entered into a profile data set selected via the
.
• In the "absolute" mode, this position is a target position. However, in the
"relative" mode it is a relative traverse path.
Consideration of residual value in case of external profile calculation
nSpeedAddValue_v
INT
Additive speed setpoint in [inc/ms]
nSpeedOverride_a
INT
Value for
• Percentage multiplier (0 ... 199.99 %) for the currently active speed.
• 16384
≡
100 % of the maximum traversing speed (display in
• If the override value is 0 %, the drive is brought to a standstill.
nAccOverride_a
INT
Value for
• Percentage multiplier (0 ... 199.99 %) for the currently active acceleration.
• 16384
≡
100 % of the parameterised acceleration of the corresponding operating
mode.
• If the override value is 0 %, acceleration ceases.
nSRampOverride_a
INT
Value for
• Percentage multiplier (0 ... 100 %) for the currently active acceleration.
• 16384
≡
100 % of the parameterised S-ramp time (
).
• Values > 16384 are ignored.
Note!
If the
nSRampOverride_a
input remains unconnected or if an override value of "0 %"
is selected, activation of the S-ramp override causes deactivation of the S-ramp time.
• Deactivation of the S-ramp time before the start of a profile with S-ramp time
causes linear ramp generation.
• Deactivation of the S-ramp time during a traversing process, however, is not
accepted immediately in the profile generator, but the profile generator checks
automatically when an online change of the ramp form can be carried out and
then initiates it automatically.
bLimitSwitchPos
BOOL
Input for
(positive)
bLimitSwitchNeg
BOOL
Input for
(negative)
bHomingMark
BOOL
Input for pre-stop mark/pre-stop signal for homing
• Relevant for
"4" ... "7".
