Tome promiň, toto je další příklad, kdy nelze otázku rozdělit a položit ji samostatně.
Kontext:
The ACE ECU powers the two directional spool valves with a 200Hz PWM ‘hit’ and ‘hold’ current control feed. This feed is similar to the feed sent to the proportional pressure control valve, except that this feed is not continuously variable. The ECU controls the pulse width to one of two levels, either the ‘hit’ current or the ‘hold’ current. The current supplied to all solenoids is independent of battery voltage. The ‘hit’ current is a minimum of 3.75 amps for 250mS at which point the current is dropped to a ‘hold’ current of 1.65 amps ± 0.3 amps. The chart below demonstrates the current/time characteristics of the directional spool valves.
