2 / 3 axis joystick

JP

DESCRIPTION

JP is a 2 or 3 axis electronic joystick with power outputs, able to
directly control up to 6 proportional solenoid valves with PWM
outputs proportional to joystick movements.

Joystick movements are derived from the measurement of the
magnetic field produced by permanent ferromagnets; the
measurement is taken through redundant Hall effect probes. This
kind of probes are not subject to usury.

JP contains a microprocessor electronic card; this makes the
joystick very reliable and highly customizable.

Also the push button panel is customizable.

Main characteristics:

- you can control two or three proportional indipendent axis (4 or
6 PWM outputs) or just one proportional output (PWM) with 4 or
6 ON/OFF outputs

- optional "virtual cross" to forbid diagonal movements

- linear or parabolic output curve

- up to 3 speed set selectionable by two input

- straight BYPASS output, with delayed turn off

- FAULT output

- standard or capacitive dead man switch

- indipendent regulation (for each semiaxis) of
l minimum current
l maximum current
l rise timeramp
l fall timeramp

- PWM frequency adjustable from 50 to 300 Hz

- power supply voltage from 10Vdc to 30Vdc

- completely resinated electronic card

- third proportional axis THUMBWHEEL ready to mount

- provided with a 50 cm long unpluggable cable

with power outputs (PWM)

WORKING MODE

The FAULT output in normal operating conditions supplies a positive output (max 2,5A).
In faulty conditions the FAULT output is turned off.

Connecting this signal to a system that puts the installation in safety conditions it is possible to stop the machine
operations in case of joystick fault.

The BYPASS output is turned on (positive output max 2,5 mA) every time the joystick is moved from the zero position.
When the joystick is released the output is turned off with a 0,4 seconds delay (programmable).

SIGNALS

The red and the green LEDs under the joystick are used to show different working conditions.
In normal operating conditions, the red LED is used as a power supply LED; it is turned on when the power
supply is present.

Red LED is turned off for a little while when bypass output is turned on or off.

In case of faulty operations the two LEDs flash in various modes depending on the fault type:

RED LED

Two flash: system turned on with the joystick not at zero position. Outputs will stay turned off. It is necessary

to turn off the joystick and turn it on again releasing the lever.

Four flash: Internal error on the magnetic sensors (excessive signal difference between the two probes of
the same channel) or movement of the lever too fast. It remains blocked until it is turned off.

Five flash: Internal error on the magnetic sensors or on the third axis input (signal out of range). It remains
blocked until it is turned off.

Seven flash: Calibrating parameters not valid. It remains blocked until it is turned off.

GREEN LED

When you move the joystick, the green led is turned on proportional to the greater current supplied. If joystick
is not plugged or a wired is broken, the green LED will stay turned off because no current will be supplied.

RED and GREEN LED at the same time

One flash at second: joystick has to be calibrated. Follow the appropriate procedure (reserved).

VIRTUAL CROSS

PWM outputs are turned on to regulate the current that flows in the load proportional to the movements of the
joystick. If you activate the "virtual cross" function, you will be able to move joystick in just one direction at a time:
the first manoeuvre done forbids all the other manoeuvres until the joystick will return at rest position.
Otherwise, if the "virtual cross" function is not activated, you will be able to do two manovreus at the same time,
by moving the joystick in diagonal direction.
The "virtual cross" fuction, if activated, is referred only to the two principal axis; the third axis, if present, will
continue to work indipendently to the two other axis.

PROGRAMMING MODE

To adjust JP working parameters, it is necessary to plug the PRG2 programming keyboard into the appropriate
connector. JP automatically recognise PRG2 connected and modify his working way to allow current calibration as
described below

Adjustable parameters:

The number of flashes of the programming keyboard LED indicates the programming step in which you are.
As PRG2 is connected You are in step no. 1.

By the pressure of "PREV" and "NEXT" push buttons you are able to navigate through the programming steps;
otherwise, by the pressure of "+" "-" push buttons you are able to increase and decrease the parameter
corresponding to the actual programming step.

At the end of the programming procedure, you have to push "PREV" and "NEXT" push buttons at the same time
to save in memory the new parameters value. If You do not give the SAVE command all modification will be loose
when JP is turned off.

Step 1: minimum current regulation (manoeuvres start up speed)
Step 2: maximum current regulation (manoeuvres max speed)
Step 3: rise timeramp regulation (manoeuvres acceleration speed)
Step 4: fall timeramp regulation (manoeuvres deceleration speed)
Step 5: bypass delay regulation (bypass delay time when all the manoeuvres stop)
Step 6: PWM frequency regulation (to reduce the solenoid valves histeresis)

with power outputs (PWM)

For the programming steps from 1 to 4 it is necessary move the joystick to choose the manoeuvre which has to
be regulated. Actually, it is possible to set different values of min/max currents, rise/fall timeramp for each
movement (semi-axis).

During the programming mode, joystick continues to work normally to give you a real time feedback of the
changes done.

The only programming step which modifies joystick behaviour is step number 1, in which you regulate the
manoeuvres start up speeds. When the joystick is into this programming step, when you move the joystick the
manoeuvres will be turned on only at their start up speed; You have to adjust start speed until all manoeuvres will
start to move very slowly or are near to start.

When You move into programming step number 2, to tune maximum speed, You can verify the complete range of
the output currents from the minimum speed (regulated in the programming step number 2) to the maximum
speed (regulated here).

While the programming steps for 1 to 5 give you a real time feedback of the modifications, the programming step
number 6 (PWM frequency regulation) does not. If you cannot estimate the effects of the modifications, you have
to do a "blind" regulation.

So you have to know the right frequency value for the solenoid valve that you are using (usually indicated by
manufacturer). Find in the following table the index that correspond to the requested frequency.

When you are in programming step number 6, press for at least 2 seconds the "'-" button (in this way you reach
the 0 value of the frequency parameter). Then push the "+" button a number of times equal to the desired
frequency corresponding number.

NOTE: Remember to save parameters before turning off the joystick.
