English term or phrase: \"frequency slow-start\"
Contexte: "diesel heater"
The system integrates the industry-leading heat controls and frequency slow-start.

Je ne comprends pas "frequency slow-start". La suite du document (plutôt marketing) ne parle ni de "frequency", ni de "slow-start" d'ailleurs.

Quelqu'un aurait-il une idée?

Merci à toutes et à tous

Demarrage lent en basse fréquence


Explanation:
Le ventilateur du souffleur doit être actionné par un variateur de fréquences qu'on fait tourner à basse vitesse CAD en fréquence basse au début probablement pour ne pas créer de chocs thermiques

ll n'y a pas vraiment de progression dans ce processus, ça peut être un démarrage lent ou rapide par variateur de fréquence. D'ailleurs slow = lent....

soft start ne veut pas dire slow start

c'est le lien parfait qui indique que démarrage progressif = soft start


"Soft starting
Sanftanlauf
Démarrage progressif
Slow start of a machine when it is first switched on (0.5 -1 second). As a result the restoring torque is strongly reduced during the starting phase. (See also Types of Electronic Control)"

slow start = démarrage lent en toute logique

"Factory-Installed Options
Variable Frequency Drive (VFD)

The blower motor on your machine requires a surge of electrical current when
starting. This means that the amount of power needed to initially start the motor is
larger than the power required to keep it running. The motor may not start if the
power source does not provide enough current to overcome the surge.
Machines equipped with generators include a Variable Frequency Drive (VFD).
The VFD (a) allows the motor to start at a low RPM with a gradual increase to full
operating speed. This reduces the amount of current needed to start the motor.

Savez pas lire les références? "Soft starting" = "Slow start ".
"slow, c'est un état statique...." ne veut strictement rien dire.
" VFD (a) allows the motor to start at a low RPM with a gradual increase to full
operating speed.
" dans la référence que j'ai postée. Si vous avez des problèmes de comprehension, je peux vous traduire en français.
