REXROTH IndraDrive M - Power Dissipation

6-8 Electrical Data Rexroth IndraDrive M
DOK-INDRV*-HMS+HMD****-PR04-EN-P
Note: Depending on the electric rotational frequency, the output
current is reduced for thermal protection of the power section.
The output current is reduced when the value of the electric
rotational frequency falls below 3 Hz.
Power Dissipation
The level of power dissipation occurring in power sections can be
ascertained from the following. In the diagrams basic and current-related
power dissipation are summarized.
