2-8 Description of Operation
Mode 30
EMULATE SPEED REFERENCE (ESR) – Europe
The speed reference to the Drive will be one of the following:
• The press line speed, which enters the Drive at the Digital
Reference input of the DRA board.
• A preset speed for Auto-Slack and Run Reverse Dancer
High (RRDH) (Slack Remove). Refer to the State Logic
Diagram in the system binder.
• An “Emulated” line speed from a potentiometer.
Drive reference control mode 30 can be observed in Parameter 597
which is a “read only” Parameter if the proper input conditions are
met. Refer to the Drive Reference Control State Diagram in the
system binder.
The combination of digital input number 9 of the DRA board and bit
0 of Parameter 572 set high will determine which speed reference will
be used by the Drive to enter either mode 21 or mode 30. Mode 30 is
used for testing and calibrating purposes, to simulate a running press.
Mode 21 is the normal speed reference mode for the Drive to follow
the line speed of the press during normal running conditions.
Mode 31
AUTO-SLACK TIGHT VARIABLE REFERENCE (ASTVR) –
Asia-Pacific
With the proper input conditions present as shown on the Drive
Reference Control State Diagram in the system binder, Mode 31 will
be entered and allow the Auto-Slack speed to be adjustable by an
external means such as a potentiometer connected to analog input
number 2. The combination of Bit 1 of Parameter 572 set high, and
the Auto-Slack digital input number 7 set high will access this mode,
which can be observed in the “read only” Parameter (ROP) 597.
