Description

Retained paddle is a single axis electronic joystick with PWM outputs, able to directly drive a couple of PWM solenoid valves..

Working mode
MAP2L joystick is designed to directly control two proportional solenoid valves (one section of an electrically controlled hydraulic distributor). The PWM command of the coils is feedback controlled, in order to guarantee the current stability
indipendently to external factors (power supply voltage, coil temperature, ...).

Main characteristics:
-  with version "retained paddle" but also available friction version (paddle returning)

- one proportional section (A+B) direct control (2 PWM outputs max 2.5A);
- adjustable minimum/maximum current for each directions (A+B);
- adjustable rise/fall timeramp up to 25 seconds (step 0.1s);
- adjustable PWM frequency from 50 to 300 Hz;
- input for speed reduction or deadman feature or "fault" output (default);
- output curve shape: linear or parabolic (selectable);
- DV digital output is activate when PWM output is on;

All working parameters are adjustable through a serial port and the ® Windows SepSim program using a special serial port adapter (AISR). The version with voltage signal output is also available (MAS2L)
