1. UNIT DESCRIPTION This unit is especially designed to be used on punch presses. It allows displaying the position of the X and Y axes, controlling them as well as the raising device (H), editing and executing part programs etc. The axes may also be moved manually from the dro keyboard or externally with footswitches. 1.1 FRONT PANEL (SEE OPERATION MANUAL) 1.2 REAR PANEL 1 2 3 Dimensions of the Built-in model (in mm): On the back of the unit, the following items may be found: 1.- Power switch. 2.
X2.- SUB-D type 37 pin female connector to connect the digital inputs and outputs as well as the analog outputs. X3.- SUB-D HD type 15-pin female connector for X axis feedback device. X4.- SUB-D HD type 15-pin female connector for Y axis feedback device. X5.- SUB-D HD type 15-pin female connector for 2nd axis feedback device. auxiliary Y' axis (only on model "B"). X7.- SUB-D type 9 pin male connector for the RS-232-C serial line connection.
2. CONNECTIONS AND CHARACTERISTICS The connection for the RS-232 serial line (optional X1 connector) is not described in this manual; but in a supplement for it. 2.1 CONNECTION OF THE FEEDBACK SYSTEMS The feedback systems (scales or encoders) are connected via SUB-D HD type 15-pin female connectors: X3 and X4. Characteristics of feedback inputs: X3, X4 and X5: +5V input consumption: 250 mA - Admits square-wave signal (TTL).
2.2 INPUT/OUTPUT CHARACTERISTICS (X2) A 37-pin female connector is used. Signal characteristics of connector "X2": The supply voltage is at +24V (±25%), thus the threshold between a "0" and a "1" will be about +6V.
2.3 INPUT/OUTPUT CONNECTION (X2).
PIN 11, 12, 30, 31 FUNCTION Limit switches. Hardware DESCRIPTION In MANUAL mode, they limit the movement in the corresponding direction. In EXECUTION mode, they abort the program.
2.3.2 OUTPUT DESCRIPTION If any of the outputs is going to be connected to some highly inductive device, a "1N4000" type diode must be installed in antiparallel. It is not required on auxiliary relays of less than 20 mA. The drives are enabled with auxiliary relays (section 5.2). PIN 5, 6, 7, 24, 25, 26 18, 37 FUNCTION Axis enable FAST/SLOW DIRECTION PAR46 Analog voltage outputs. PAR 64, PAR65 DESCRIPTION Enabling drives or frequency inverters for open loop control.

2.3.4 BLOCK CHANGE SYNCHRONISM. MODELS A, A1 Description of the diagrams according to positions a, b and c. There are three ways to synchronize when going from one block to the next at the end of a bend. If a pressure gage (transducer) is installed, P64.6 = 1, the editor offers the possibility to program the work pressure on the header page N0. 1. With the transducer connected to input I18 (P64.

With X and Y axis already in position, the FAST approach is activated from the MANUAL control station IE15 or only SLOW from the "BEND" footswitch (I8). 2. In the change position, Y= PAR33 or programmable, the SLOW speed is activated with the "BEND" footswitch. 3. When pinching the sheet metal, Y = thickness, it resets O29 to wait for the return of the X axis. 4.

2.4 MACHINE REFERENCE (HOME) SEARCH In this mode, the initial values are preset in a fixed reference position. If PAR14.4 = 1 on any axis, home search is mandatory on that axis every time the machine is turned on. This unit starts in mode. To quit this mode without homing, press and key in the access/exit code: 719200 If PAR14.4 = 0, home search is only required on machine setup.
2.4.2 Y AXIS REFERENCE (HOME) SEARCH. MODELS A AND A1 a- If the machine has travel limit switches, the home search procedure is the same as the one described for the X axis; but it is only enabled if I13 = 1, ram at top dead position. b- If the machine does NOT have travel limit switches (which is very common on down stroke models), set PAR14 bit 1 = 1 to indicate that the reference position is floating.

It displays the word "START". to reach the home position. · Actuate on the "BEND" footswitch until the punch or the die (on up-stroke models) goes to its final position.
2.4.4 Y AXIS HOME SEARCH. MODEL "C" An up-stroke or down-stroke model "C" has a linear encoder and controls the actual (real) position of the ram using foot switches. It usually has travel limit switches. If PAR00 bit 6 = 0, has been set for a linear encoder with a regular reference mark (without distance-coded reference marks), the homing procedure is the same as described in section 2.4.2 (a) If PAR00 bit 6 = 1 has been set for a linear encoder with distance-coded reference marks.
