Which term defines the duration, in a 1/63-second window, that current is allowed to energize the solenoid?

Which term defines the duration, in a 1/63-second window, that current is allowed to energize the solenoid?

• A. shift control logic
• B. slow adaptive mode
• C. fast adaptive mode
• D. duty cycle

Answer: (D)

Duty cycle is the fraction of each cycle during which the solenoid is energized. Here, a cycle lasts 1/63 of a second (about 15.87 ms). The on-time within that cycle—the duration the current is allowed to energize the solenoid—defines the duty cycle. It’s usually expressed as a percentage: on-time divided by the total cycle time. This percentage determines the average current through the solenoid, affecting its force and heating. The other terms describe different control ideas or modes, not the on/off timing of the coil within each cycle.
