Function Signal FUM (Pin 8)

The IP 266 outputs the FUM signal when it is ready for operation and has valid
machine data at its disposal.
C A U T I O N :
For reasons of safety, you may enable your power section only when the IP 266
has output the FUM signal. To do this, you must interlock the power section's
Enable input with the FUM signal. If the power section has no Enable input, you
must establish the interlock in some other way.
The FUM signal is removed immediately when invalid machine data is transferred
to the IP 266.
The FUM signal is reactivated when the error has been rectified and correct data
forwarded to the IP.
2.5.6

Position Reached (Pin 9)

The "Position Reached" signal indicates error-free completion of a positioning
operation with absolute or relative target specifications.
The signal is generated twice:
• As status bit in the input block (see Section 7)
• As signal on terminal block PIN 9
The following conditions must be fulfilled in order for this signal to be
generated:
• The setpoint position must have reached the specified target coordinate (t
• The actual position must lie within the tolerance limits for zero-speed
monitoring (t ).
