SmartController (CR2500) V05
PWM in the ecomatmobile controller
Hydraulic control in PWM
If the function input MANUAL is set to "0", the controller is always self-optimising. The performance of
the controlled system is permanently monitored and the updated compensation values are
automatically and permanently stored in each cycle. Changes in the controlled system are immediately
recognised and corrected.
Info
Input X of the function CONTROL_OCC should be supplied by the output of the JOYSTICK functions.
Parameters of the function inputs
Name
Data type Description
ENABLE
BOOL
TRUE: function is executed.
FALSE: function is not executed.
INIT
BOOL
TRUE: function is initialised, 1st cycle.
FALSE: during processing of the program.
R_RAMP
INT
Rising edge of the ramp
in [increments/PLC cycle] or [increments/TIMEBASE].
0 = without ramp
F_RAMP
INT
Falling edge of the ramp in
in [increments/PLC cycle] or [increments/TIMEBASE].
0 = without ramp
TIMEBASE
TIME
Reference for rising / falling edge of the ramp:
t#0s = rising / falling edge in [increments/PLC cycle]
else = rising / falling edge in [increments/TIMEBASE]
X
WORD
Input value in [increments].
Standardised by function NORM_HYDRAULIC.
XH
WORD
Max. input value in [increments].
XL
WORD
Min. input value in [increments].
MAX_CURRENT
WORD
Max. valve current in [mA].
MIN_CURRENT
WORD
Min. valve current in [mA].
TOLERANCE
BYTE
Tolerance for min. valve current in [mA].
When the tolerance is exceeded, jump to MIN_CURRENT is
effected.
CHANNEL
BYTE
0...x PWM output channel (values depend on the device).
PWM_FREQUENCY
WORD
PWM frequency for the connected valve in [Hz].
DITHER_FREQUENCY WORD
Dither frequency in [Hz].
DITHER_VALUE
BYTE
Amplitude of the dither value in [%] of MAX_CURRENT.
MODE BYTE
Controller
characteristics:
0 = very slow increase, no overshoot
1 = slow increase, no overshoot
2 = minimum overshoot
3 = moderate overshoot permissible
