8.4.3.2 Hardware limit switch
The travel range limits are monitored by means of limit switches via the inputs
bLimitSwitchPos and bLimitSwitchNeg of the LS_MotionControlKernel
system block.
The two inputs react to the TRUE state.
In TA "Table positioning"
, the two inputs are connected to the digital inputs provided
for connection of the limit switches.
Behaviour when hardware limit switches are active
If one of the two monitoring inputs is set to TRUE:
– The error response "TroubleQuickStop", takes place in the Lenze setting, i.e. the drive
is brought to a standstill in the deceleration time set for the quick stop function
irrespective of the setpoint selection. The error response can be parameterised in
C00595/1
and C00595/2.
– The error message "Ck01: Pos. HW limit switch" or. "Ck02: Neg. HW limit switch" is
entered in the logbook.
– Bit 10 ("Pos. HW-Limit Detected") or bit 11 ("Neg. HW-Limit Detected") is set in the
MCK status word
.
– Depending on the parameterised error response, the drive cannot traverse until the
error has been acknowledged.
Stop!
The limit switches are only evaluated if the limit switches for the respective
operating mode have been activated.
• For the "Manual jog
" operating mode, travel range monitoring by means of
hardware limit switches is off in the Lenze setting of C01230
.
• In the "Homing
" and "Positioning" operating modes, the travel range
monitoring is generally switched-on.
Parameter Info Lenze setting
C01218
- Bit 2 HW limit switch for position follower on/off On
C01219
- Bit 2 HW limit switch for speed follower on/off On
C01230
- Bit 2 HW limit switch for manual jogging on/off Off
Note!
If the digital inputs used for connecting the limit switches are fail-safe inputs
(tripping at LOW level), you simply change the terminal polarity of the
corresponding digital inputs in C00114
.
