
MICRO INCH :
The micro inch signal indicates that the controller is directed to operate at the micro inch speed.
The two enables and clutch on signal are need as well. 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 closure that puts the 115 VAC of the press control
into the.

REVERSE :
The reverse command is sent to the press control to indicate that the press is to operate in the
inch or micro inch mode in the reverse direction. The two enables and an inch command are
needed as well. The controller uses this information to establish either the inch-reverse or micro
inch-reverse mode. If the reverse command is issued with any command other than the inch or
micro inch, a fault will be generated. The reverse command cannot be changed when enable is
present; otherwise, a fault will be generated. The reverse signal consists of a press control
contact closure that puts the 115 VAC of the press control into the brake control board.

CONTROL POWER ON:
The control power on signal is provided by the press control to activate the 115 VAC control
power to the controller. This will close a contact in the secondary of the controller transformer.

STOP-ON-TOP – CONTINUOUS MODE:
The continuous mode signal is issued by the press control to indicate that the controller should
run continuously without stopping on top If the signal is removed execute a normal stop-on-top,
If the continuous command is not present when the creep angle is reached a stop on top is
performed. The control will command creep speed at the creep angle and stop at when the stop
angle is reached.

FAULT RESET:
The fault reset command is a signal from the press control to reset any fault condition in the
controller, allowing for continuation of operation. If the condition is a result of a clutch current
fault or a brake current fault, it will be necessary to wait the on the setting of parameters H.14 for
the clutch and H.15 for the brake before resetting; otherwise another fault will be generated. This
delay is necessary to allow time for the coil to cool down. The fault reset signal consists of a
press control contact closure that puts the 115 VAC of the controller into the brake control board.
9.2 CONTROL - OUTPUT SIGNALS
The CES controller provides seven different solid-state output signals that function as contact closures
and contact openings, according to the conditions called for. The output signals that occur during
different phases of operation are as follows: Normal Stop, Stop Main Motor Fault, Stop Now Fault, Stop-
on-Top Fault, Control Failure Fault, Clutch ON and E-Relay. The first five items (up to control fault are
protected by miniature fuses on the brake control board. The others come from the press control and are
not protected.

NORMAL STOP (OUTPUT):
The normal stop signal input from, controller indicates that the control is about a normal stop (due
to reaching the stop angle in stop on top mode) or in the case of a commanded stop input (enable
release) from the press control. Receipt of the normal stop output (led on output low) signal from
the CES controller indicates that the CES controller has commanded the press drive
to be at zero
speed. Upon receipt of this normal stop signal, the press control is directed to remove the enable
signals and set the friction brake and remove the clutch on signal after an appropriate delay. The
normal stop output will be cleared (led off output high) by the press control giving the enable
signal the next time it is desired to run. This signal is programmable. See hidden parameters I.4
