PSU - 8 Positioning Drive Setup Ver. 0002
Home search setting.
It is possible to set the home searching direction and the boolean logic of the home switch.
Bits 1 and 2 of parameter PP147 -S147- set the positive home searching direction and
whether the home switch closes its contacts or opens them when activated.
Electrical connection of the "home switch" and parameter setting.
When connecting the electrical contact to one of the digital inputs of the drive.
If no PLC is used, assign variable PV200 -S400- to one of parameters IP10 ... IP13 (in the
Sercos nomenclature, F901 ... F904). Connect the "home switch" to the digital input
associated with the chosen parameter.
If a PLC is used, use an instruction to indicate that bit "0" of parameter S400 must take
the value of one of the digital inputs (for example I1). The instruction would be: I1 =
B0S400.
When the electrical contact is taken to one of the digital inputs of the 8070 CNC.
The CNC communicates the status of the contact via Sercos; but the Drive is still the one
controlling the home search process.
