Rockwell Automation 1395 Reel Tension Paster Adapter - Manual (Page 19)

Publication 1395-RTP-5.1 - September 1997
Description of Operation 2-7
Mode 27
PROCESS TRIM ENABLE
This enables the process trim in the Drive to allow proper tensioning
of the web. Movement of the dancer will either add or subtract from
the press speed reference in order to hold the dancer close to the
center position at all times during normal run.
Global RTP Drive –
USA / Europe / Asia-Pacific Two new drive reference control modes have been added to allow for
adjustable Auto-Slack Speed Control (Asia-Pacific), or for adjustable
Emulate Speed Reference Control (Europe).
Either of these customer inputs will enter the Drive at analog input
number 2 of the Digital Reference Adapter (DRA) board of the
Bulletin 1395 Drive. Parameter 572 is a configuration Parameter that
is to be used to determine if analog input number 2 will be used for
either adjustable Emulate Speed Reference (ESR), or adjustable
Auto-Slack Reference, defined as Auto-Slack Tight Variable
Reference (ASTVR). Digital input number 9 of the DRA board must
also be held high to access mode 30, ESR.
Parameter 572
The Parameter 572 configuration truth table follows. Refer to the
Logic State Diagrams in Chapter 6 of this manual.
Note: Parameter 572 Bit 2 is set to a value of one for CT50P design.
Without making any link changes to the Drive, these two new modes
of operation can be accessed by the proper configuration of Parameter
572 and the customer supplied inputs to analog input number 2 of the
Digital Reference Adapter board.
Following are the descriptions of the two additional reference control
modes.
Bit 2 Bit 1 Bit 0
0 0 0 = USA
0 0 1 = Europe – ESR Mode 30
0 1 0 = Asia-Pacific – ASTVR Mode 31
