DESCRIPTIONS OF KEY FEATURES
Active-High Digital Inputs
e 1356 /1356P has eleven digital inputs. Each input is digitally ltered to
eliminate switch “bounce” or noise in the signal. A power resistor pull-down
to B- at each input provides active high to B+.
High Frequency Driver Outputs
e 1356 /1356P contains two driver outputs. One can sink up to 1 amp
through an inductive or a resistive load; the other can sink up to 3amps through
an inductive or a resistive load. Internal yback diodes to B+ prevent voltage
spikes. High frequency PWM (16 kHz) provides smooth current to the load.
Constant Current or Voltage Outputs
e two driver outputs can work in Constant Current mode or in Constant
Voltage mode.
In Constant Current mode, the software runs a closed loop PI controller
to provide an average constant current. is current is commanded over PDO
as a 0–100% command based on the maximum current setting (set through a
Curtis programmer or an SDO).
Each output can also be programmed for Constant Voltage mode. In this
mode, the battery voltage is monitored and the PWM command is corrected
by a feed-forward controller to provide a constant average voltage commanded
over the PDO (a 0–100% command based on the maximum voltage setting).
In addition, each output can also be programmed to provide a directly
commanded PWM% output (Direct PWM mode) or shut o to be used as
an input (Active-High Digital Input Only mode).
Programmable Dither for Hydraulic Valves
Dither is a small variation in the command that keeps the seals of a proportional
valve oiled. is lubrication allows the valve to move freely for accurate PV
control. Dither is only active on drivers in Constant Current mode.
