recommended value; see following note
Fig. 6-1:
Technical data for mains supply and power section
Note:
Observe that the load at the motor terminal is almost
independent of the power section used.
Especially when using standard motors, make sure that they
can withstand the voltage load.
Observe section "Using Third-Party Motors in Drive System
Rexroth IndraDrive" of the Project Planning Manual "Rexroth
IndraDrive Drive System".
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.
