Limit switch
Limit switches are used to detect a certain position, whereupon a defined reaction
is carried out.
4.4.18.1 Software limit switch
Error reaction (=> see Chapter 4.3.1 Errors)
Excluded modes of operation
for software limits
Operating modes in which the software limit
switches are not active
If st33 position actual value exceeds the software position limits while a speed is
preset in the appropriate direction, the parameterised error response is triggered.
4.4.18.2 Hardware limit switch
negative limit switch source
Selection of digital inputs for the negative and posi-
tive limit switch (=> also chapter 7.1 Digital Inputs;
no STO inputs)
positive limit switch source
excluded modes of operation
for limit switch
Operating modes in which the limit switches are not
active
Selection of limit switch tripping conditions
Speed level in % rated motor speed from which
evaluation of the actual direction of rotation is active
limit switch forward stop mode
Selection of the error reaction when the limit switch
is reached (=> also chapter 4.3.1 Errors)
limit switch reverse stop mode
If no input is assigned to a limit switch in parameters hm06 / hm07 but a reaction is
defined in parameters pn78 / pn79, this reaction is always triggered because the
limit switches are 0-active.
If a quickstop reaction is selected in parameters pn78 / pn79, quickstop must be
activated in co32, otherwise there is no reaction. The quickstop reaction can be de-
fined via the "quickstop option code".
