Dust cover Protection Level Operating Temperature
with IP20 NEMA 1 When operating at rated current, the surrounding temperature must be
between -10–40°C. When the surrounding temperature is over +40°C,
decrease the rated current by 2% for every 1°C increase in temperature. The
maximum allowable surrounding temperature is 60°C.

 Normal Control Ambient Temperature Derating Factor Curve
1. Derating of the Power Regenerative Unit decreases by multiplication
.
2. Derating is required not only when there is a continuous regeneration, but in addition the conditions
covered by the Performance Curve are required to have the same derating ratio.
Calculation 1:
When the ambient temperature = 40°C, ED = 10%, the braking capacity of the Power Regenerative Unit =
150%, 10 seconds (See REG2000 Performance Curve).
When the ambient temperature = 45°C, see Normal Control Ambient Temperature Derating Factor Curve,
and the Power Regenerative Unit needs a derating of 10% = (45°C - 40°C) x 2%. Therefore, when ED is at
10%, the braking capacity of the Power Regenerative Unit = 150% x (100%-10%) = 135%, 10 seconds.
