Notes on Operation
The green "RDY" LED on the frontplate of the IP 267 lights up after it has
received the data.
Note:
If you send the output message frames to the IP 267 with the "FORCE VAR"
programmer function during startup, there are important points you must note
( 5.5 ).
When carrying out the following steps, make sure that the motors can be
switched off at all times (emergency OFF switches or limit switches must be
within easy reach). Assign only traversing jobs with low velocity steps at first.
• Transfer a "Forwards" or "Backwards" job with a short path and low velocity.
The drive must move smoothly.
• Check the function of the emergency limit switches (PD) acting directly on the
pulse disable.
• Check the correct execution of the "Forwards" and "Backwards" modes and,
if necessary, interchange the RP and RP
• Test both limit switches (I +, I -) acting on the IP 267. Limit switch I + must
respond at the end of the forwards approach and I - must respond at the end
of the backwards approach, otherwise you must change over the EPLUS and
EMINUS connections at the digital inputs of the IP 267 ( 3.3).
• The input "External STOP" must be connected as specified in the
configuration data ("0" active or "1" active).
