PRESS CONTROL INTERFACE - COMMANDS
ACCEPTED
The CES controller will accept nine different input
command signals from the press controller that are
available for the operator to make, they are as follows:
two Enables, Clutch Contactor ON, Inch, Micro Inch,
Reverse, Control Power ON, Stop-On-Top and Fault
Reset. Some controls also have a Stop-on-bottom
command.
ENABLE:
The enable signals are required to start the drive. These
contacts are the last contact closures in the start
sequence. The clutch contactor ON signal and the two
enable signals must all be given within 170 ms of one
another or a fault will be created. The enable contacts
must be closed in order to run. Upon opening either of
these contacts, the press control signals the CES
controller to stop the drive immediately with a command
to zero speed and to open the clutch contactor 450
milliseconds later. The CES controller responds to this
removal of enable with a normal stop signal. The enable
contact closures must be given only after all safety
features of press operation have been determined to be
in a "GO" status by the press control. The release of the
friction brake through the air pressure switch and/or the
limit switch showing friction brake travel is sometimes
used as the last event in the chain of events that
provides for the integrity of the enable signal given by
the press control to the CES controller. Redundant CES
inputs are provided to ensure that the enable signal is
present and that the receiver is not shorted.
The enable signals consist of two press control contact
closures that put the 115 VAC of the press control into
the I/O board.
CLUTCH CONTACTOR ON (INPUT):
In addition to the enable, the press control provides 115
volts to energize the clutch contactor. This ensures that
the press control has absolute control over the ability of
the CES controller to energize the clutch. This input
signal monitors the 115-volt signal. The clutch contactor
ON signal is one of the signals that activate the CR1
relay.
INCH:
The inch signal indicates that the CES controller is
directed to operate at inch
speed. The inch command is needed, along with
enable, to activate the controller in the inch mode. The
inch command can only be changed when the enable
command is not present; otherwise, a fault will be
generated.
The inch signal consists of a press control contact
closure that puts the 115 VAC of the press control into
the I/O board.
MICRO INCH:
The micro inch signal indicates that the CES controller is
directed to operate at the micro inch speed. The micro
inch command is needed, along with enable, to activate
the controller in the micro inch mode. The micro inch
command can only be changed when enable is not
present; otherwise, a fault condition will be generated.
The micro inch signal consists of a press control contact
