PressCam 8 Junior
PressCam 8 Junior
The PressCam 8 Junior is a resolver-based press automation controller that incorporates a programmable cam limit switch (PLS), timed-based brake monitor, servo feed control, four counters, and a die protection system The PressCam 8 Junior is controlled by a 16-bit computer that constantly checks the resolver for accuracy. 100 job memory.
The PressCam 8 Junior is a resolver-based press automation controller
that incorporates a programmable cam limit switch, timed-based brake
monitor, servo feed control, four counters, and a die protection system.
The PressCam 8 Junior is controlled by a 16-bit computer that constantly
checks the resolver for accuracy.
The PressCam 8 Junior has a keypad, menu, cursor buttons (for easy
navigation and operation), and a four line (20 characters each line)
vacuum fluorescent display for easy viewing purposes.
A “RUN/PROG” keyswitch is also provided where, while in the “RUN”
mode, you are not able to alter any parameter or job change. The “RUN”
mode only allows the user to clear counters and reset die sensor faults.
In the PROG mode, the Die Faults do not open up the fault relays which
allows for die setups. All other faults will cause the fault relays to open.
If the password feature is enabled, you must first enter in the three digit
password in order to pass into the PROG mode to allow parameter
changes.
• All six Limit Switch Outputs can be set to cycle (non-timed) two times per crank rotation by setting an open / close
crank angle.
• The last three outputs can be set for timed, non-timed, delayed, and hold or cycled two times per crank revolution.
• Major faults such as E-Stop, motion, brake, and sensor faults are handled by two force-guided relays (Form B Safety
relays).
• The six outputs are small, high-speed, high-capacity relays.
• Brake and die sensor inputs are optically coupled and can be either AC or DC (sourcing or sinking).
• Up to 100 Jobs can be saved using a nonvolatile memory chip. The memory chip is removable for ease of transfer.
Each Job Number stores a name and/or number up to 7 characters for easy identification.
• Built-in Brake Monitor will issue a warning when the programmed warning time is exceeded and will issue a failure
signal when programmed stop time is exceeded.
• True Motion Detection system checks for lack of motion (Motion Fault) and unintended motion (Drift Fault).
• SPM Indicator (Strokes per Minute).
• Crank angle shown graphically and in large numbers.
• Speed compensation of user selected outputs.
• Servo feed interface.
• Stroke, Batch, Quality, and Part Counters to keep track of operation.
• Password and/or Supervisory Controlled Selector Switch to prevent altering of parameters, except for the counters.
• PCLink to allow offline job creation and storage.
• Built‑in 90º and 270º stop time tester.
The heavy duty brushless resolver transducer replaces the current mechanical
rotary cam switch. This unit was designed for hostile industrial environments such as punch press mechanical shock and vibration, extreme temperature and humidity, oil, coolant, and lubrication mists.
The resolver transducer features excellent repeatability and gives absolute
shaft position feedback. High speed operation along with long transducer cable (runs up to 600 feet/183m) give the resolver transducer wide application ranges. The resolver transducer is a passive device which contains no sensitive electronics and has superb noise immunity.
The resolver mounts easily to an end of a crankshaft and can rotate
clockwise or counter-clockwise. Simple connector ended transducer cabling
is supplied to connect the resolver to the PressCam 8 Junior controller console. The PressCam 8 Junior’s microprocessor-based control constantly monitors the resolver position and displays both the angular position of the shaft and speed of the machine (tachometer). 3/4” (19 mm) resolver shaft diameter.
