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
Index Id-Text Name
0x2A12 pn18 sw.- switch limit left
0x2A13 pn19 sw.- switch limit right
0x2A14 pn20 E.SW-switch stop mode
Excluded modes of operation
0x3110 hm16
for software limits
If st33 position actual value
preset in the appropriate direction, the parameterised error response is triggered.
4.4.18.2 Hardware limit switch
Index Id-Text Name
0x3106 hm06 negative limit switch source
0x3107 hm07 positive limit switch source
excluded modes of operation
0x310F hm15
for limit switch
0x3111 hm17 limit switch handling
0x3112 hm18 limit switch speed level
0x2A4E pn78 limit switch forward stop mode
0x2A4F pn79 limit switch reverse stop mode
If no input is assigned to a limit switch in parameters
defined in parameters
limit switches are 0-active.
If a quickstop reaction is selected in parameters
activated in co32, otherwise there is no reaction. The quickstop reaction can be de-
fined via the "quickstop option code".
