Hardware limit switch

The travel range limits are monitored by means of limit switches via the inputs
bLimitSwitchPos and bLimitSwitchNeg of the

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.
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 and
does so irrespective of the setpoint selection. The error response can be
parameterised in
– 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
– Depending on the parameterised error response, the drive cannot traverse until the
error has been acknowledged.
