Brake Monitor (continued)
Stop Time Monitoring (continued)
Since it takes 125 milliseconds to determine that the position has not changed for that amount of time, the
ANS1 subtracts 125 milliseconds from the Stop Time value before reporting it to the host controller.
Start Time Monitoring
The Brake Monitor can also monitor the starting time of the press. The starting time is the time between the
activation of the Brake Input and a position change greater than (2 *
Complete Stop Count value). This timer
value is reported to the host controller with a resolution of one millisecond and a maximum value of 32,767
milliseconds. The
Start Time Limit parameter is available and gives you the ability to turn off a fault output if
the starting time is exceeded. The Start Time Limit parameter has a range of 0 to 32,767 milliseconds. One of
the sixteen outputs is programmed to be the fault output by setting the Start Time Overrun Output parameter
to the desired value.
Die Protection Monitors
The ANS1 supports up to sixteen Die Protection Monitors. Before a Die Protection Monitor can be used, it
has to be associated with one of the sixteen available inputs.

Each monitor can operate in one of five check modes, which are described below.

Each monitor has up to four programmable Check Windows associated with it. Some of the check
modes use these windows to define where and how the inputs are checked.
Each monitor has an eight bit counter associated with it. This counter is used to count the number fault con-
ditions that have occurred.

Counters count from 0 to 255 and roll over to zero if more than 255 events occur.

Counters can be programmed to continuously count faults, or reset to zero when a cycle completes
without error.
You can also assign one of the sixteen outputs to a Die Protection Monitor. When this is done, limit switch
programming on the output no longer affects it.

Each output is normally active. It will switch to its inactive state when the counter is non-zero.

You can programmatically disconnect the output from the counter value. When in this state, the output
will remain active regardless of the counter value.
Normally True Check
The input must remain active throughout the entire cycle. Check Windows are not used with this check. The
associated counter is incremented as soon as the input changes from its active to inactive state. If the counter
is programmed to be self-clearing, the counter will return to zero when the input transitions from its inactive-
to-active state. If a physical output is assigned to the Die Protection Monitor, it will turn off at the same time
the counter is incremented.
Normally False Check
The input must remain inactive throughout the entire cycle. Check Windows are not used with this check.
The associated counter is incremented as soon as the input changes from its inactive to active state. If the
counter is programmed to be self-clearing, the counter will return to zero when the input transitions from its
active-to-inactive state. If a physical output is assigned to the Die Protection Monitor, it will turn off at the
same time the counter is incremented.
