Tips and
Troubleshooting
General Issues
If an odd behavior is seen (e.g., the
In Phase
output is deactivated or is
blinking, a
Cycle Error
/
Cycle Limit Reached
error output is active) go
online and query the
CQ, FM7, FM8, FM9
and
FM10
serial command
s
.
This should indicate what the issue is.
Once a user adjustment change occurs the system can take up to two
cycles to complete the change depending on when the change is
requested in the cycle. See
Operational Timing
.
Product Ranges and Limits
The behavior of the PCM-22 is controlled by the limits/parameters
entered. They
must
match the product for correct operation. This is why
it is a not a good idea to attempt a “one size fits all” approach (i.e., one
set of product parameters for a wide range of product lengths).
There are three solutions to this situation:
1.
The simplest approach is to setup several
Master Cycle
definitions
and have each called from identical Follower cycle definitions. Each
Master Cycle
definition would cover a smaller product range. Each
Follower cycle could then be called from separate programs. This
may be accomplished with program select lines.
2.
Setup several smaller product ranges in separate
Master Cycle
definitions and only use one Follower cycle definition. This can be
accomplished by using the
FT
serial command
and a T-21 Data
Entry Panel.
For example:
CY = 1
Select Follower Cycle 1 to edit.
FT = 15
Select Master Cycle 15 to use with Follower Cycle 1.
The next time Follower Cycle 1 is started, the Master processing will
be reset and Master Cycle 15 definition will be used. The
CI2
serial
command
returns the current Master cycle.
3.
Using only one
Master Cycle
and one
Follower Cycle
definition, a T-
21 or T-60/T-61 could be programmed to change the
Master Length
Upper Limit,
Master Length Lower Limit
,
Follower Length Upper
Limit
or
Master Length Upper Limit
or
Master Length Lower Limit
Length Lower Limit
