GENERAL
Jupiter driver card S20-14087-0 is a bidirectional pulse-width modulated current coil
driver used for proportional open-loop control of the 9A electro hydraulic controlled
pumps. Input commands to the card may be voltages, current loop, or potentiometer,
single ended or differential. Multiple input commands are permitted but must be inter-
locked by the user to insure that the card is controlled by only one input at a time. The
card also features two ranges of positive and negative ramping, remote emergency
shutdown control, options for soft stop, emergency stop and reverse command, as well
as provisions for closed-loop control with the Jupiter options card S20-11716. The driver
card is packaged for panel mounting and may be operated with any 22-29VDC filtered,
1 amp power supplies or with the Jupiter 900 power supply 762-30026, which provides
the required DC power in a panel mount package.
Open loop control The driver card with its power supply accessory is used for open-loop control.
It provides multiple input commands and ramping. The panel mounted power supply fur-
nishes the driver card with regulated DC power and features screw terminals for
simplified panel wiring.
Closed loop control The options card, S20-11716, is used in conjunction with the driver card for precise
closed-loop control. It features digital and DC tachometer feedback, horsepower limiting,
and PI control of feedback error. A panel mounted eurocard holder with
screw terminals is available for easy mounting. Power for the options card is obtained
from the driver card’s power supply.
