1.2 SERVOPACK OVERLOAD CHARACTERISTICS
The allowable conduction time of CPCR-MR[?.C • Hot start: The overload characteristic when
is shwon in Fig. 1.2 (a) through (h). Servopack is running at the rated load and so
saturated thermally.
In Fig. i. 2, cold and hot starts mean the follow-
ing: • Ambient temperature: For these data,the ambient
• Cold start: The overload characteristic when temperature is 60°C. At lower ambient tempera-
tures, the allowable conduction time increases.
Servopack at the ambient temperature starts
to operate.
