III. INCH REVERSE MODE (RUN AT)
The CES controller will be in the inch reverse mode if the
following conditions exist:
1. Enable signal is present
2. No fault is present
3. Reverse is present
4. Inch is present
5. Micro inch is not present
6. Clutch contactor ON signal is present
7. Brake contactor is closed
8. The main motor is programmed to run in the reverse
direction
When in the inch reverse mode, the CES controller
functions in the following manner.
The clutch ON command closes the clutch contactor.
The reference ramps from 0 to the inch reference at the
inch acceleration rate. Upon removal of the enable, the
drive reference goes immediately to 0 and the drive
decelerates to Zero speed. At the time the enable is
removed, the 450-millisecond clutch safety timer is
initiated. After 450 milliseconds, the clutch contactor is
dropped out by removing clutch ON. The enable signal
should be the last signal received to eliminate faults.
The drive may be jogged in the inch mode by toggling
the enable signal.
The inch reverse mode will be indicated by simultaneous
illumination of the "Inch" and “Reverse" LEDs on the
keypad and display board.
IV. MICRO INCH FORWARD MODE (RUN AT)
The CES controller will be in the micro inch forward
mode if the following conditions exist:
1. Enable signal is present
2. No fault is present
3. Reverse is not present
4. Inch is not present
5. Micro inch is present
6. Clutch contactor ON signal is present
7. Brake contactor is closed
When in the micro inch forward mode, the CES
controller functions in the following manner,
The clutch ON command closes the clutch contactor.
The reference ramps from 0 to the micro inch reference.
There is no acceleration rate in micro inch. Upon
removal of the enable, the drive reference goes
immediately to 0 and the drive decelerates to zero
speed. At the time the enable is removed, the 450-
millisecond clutch safety timer is initiated. After 450
milliseconds, the clutch contactor is dropped out by
removing clutch ON. The enable signal should be the
last signal received to eliminate faults. The drive should
be jogged in the micro inch mode by toggling the enable
signal.
The micro inch forward mode will be indicated by the
"Micro Inch" LED on the keypad and display board.
V. MICRO INCH REVERSE MODE (RUN AT)
The CES controller will be in the micro inch reverse
mode if the following conditions exist:
1. Enable signal is present
2. No fault is present
3. Reverse is present
4. Inch is not present
5. Micro inch is present
6. Clutch contactor ON signal is present
7. Brake contactor is closed
8. The main motor is programmed to run in the reverse
direction
When in the micro inch reverse mode, the CES
controller functions in the following manner.
The clutch ON command closes the clutch contactor.
The reference ramps from 0 to the micro inch reference.
Upon removal of the enable, the drive reference goes
immediately to 0 and the drive decelerates to zero
speed. At the time the enable is removed, the 450-
millisecond clutch safety timer is initiated. After 450
milliseconds, the clutch contactor is dropped out by
removing clutch ON. The enable signal should be the
last signal received to eliminate faults. The drive may be
jogged in the micro inch mode by toggling the enable
signal.
The micro inch reverse mode will be indicated by
simultaneous illumination of the "Micro Inch" and
"Reverse" LEDs on the keypad and display board.
VI. FAULT MODE
Two fault indicators designed into the controller are the
DMR Fault and First Fault (15-775-2).
The fault mode is entered if any fault is generated. Once
the fault mode has been entered by the initiation of a
fault, the CES controller remains in the fault mode until
the fault mode is remotely reset by the press control
issuing a fault reset command. The fault mode can be
reset locally from the CES controller keypad. Call up
Parameter 63, Clear Faults, and using the Down Arrow
(↓) reduce the faults to zero.
In the fault mode, various faults are stored, indicated and
transmitted to the press control by the CES controller. In
the case of all faults, the press is stopped. There are
various levels of faults; and the urgency with which the
press is stopped differs with the different levels of faults.
The four faults that the CES controller will diagnose are
as follows: Stop Main Motor Fault, Stop Now Fault, Stop-
On-Top-Fault and Control Fault. These are fully
described below. For quick reference during operation,
refer to Table 3-3 and/or 3-4.
