Operation at Ambient
Temperatures > 40 °C
Operation with Internal Braking
DOK-ECODR3-DKC**.3-CS*-PR02-EN-P
Note: In the following it is understood that the other conditions (max.
installation altitude of 1000 m, no internal braking power,
three-phase operation) are kept!
The maximum allowed ambient temperature is 55 °C. Operation above an
ambient temperature of 40 °C causes a derating of 2% per 1 °C:

Power
Note: In the following it is understood that the other conditions (max.
ambient temperature of 40 °C, max. installation altitude of
1000 m, three-phase operation) are kept!
Using the internal braking resistor causes additional power dissipation
(heat) in the drive controller and derating (200 W and 400 W drive
controllers only):

Fig. 4-13: Derating when using the internal braking resistor
Note: In case the above derating causes problems in servo
operation, you can use the full power of the drive controller by
removing the existing jumper at the RB2 and RB3 terminal
connectors and connecting an external braking resistor to the
RB1 and RB2 terminal connectors.
