The activation of the stall protection loop is displayed in parameter

P-0-0046, Status word of current controller (bit 12: stall protection

loop):

• bit 12 = 1 → stall protection loop active

In addition, the diagnostic message E8040 Torque/force actual value

limit active is generated.

• bit 12 = 0 → stall protection loop not active

The activation of the current limitation loop is displayed in parameter

P-0-0046, Status word of current controller (bit 13: current limitation

loop):

• bit 13 = 1 → current limitation loop active

In addition, the diagnostic message E8041 Current limit active is

generated.

• bit 13 = 0 → current limitation loop not active

The status of the velocity search mode can be read in parameter

P-0-0046, Status word of current controller (bit 14: search mode):

• bit 14 = 1 → search mode active

• bit 14 = 0 → search mode not active

Field-Oriented Closed-Loop Current Control

Brief Description

The drive function "field-oriented current control" is made available in the

base package "closed-loop".

Note: The current loop was preset for all Rexroth motors and

normally does not have to be adjusted.

For notes on how to commission the current loop for third-

party motors see "Third-Party Motors" in chapter "Motor,

Mechanical Axis System, Measuring Systems"!

In the case of field-oriented closed-loop current control, the internal

control task consists in generating the transformed currents I

and I

closed-loop-controlled form:

• I

(field-generating current) → PI loop for I

• I

(torque-generating current) → PI loop for I

With the firmware, you can operate asynchronous and synchronous

motors in the entire speed range, including field weakening.

As a basic principle, we distinguish the following three working ranges:

• base speed range (1) → constant torque

• field weakening range (2) → constant power

• field weakening range (3) → power limit range
