Description
Selects a mathematical function between the reference
sources selected by parameters
26.12 Torque ref2 source. See diagram at
source.
Signal selected by 26.11 Torque ref1 source
reference 1 as such (no function applied).
The sum of the reference sources is used as torque reference
1.
The subtraction ([26.11 Torque ref1
ref2 source]) of the reference sources is used as torque
reference 1.
The multiplication of the reference sources is used as torque
reference 1.
The smaller of the reference sources is used as torque
reference 1.
The greater of the reference sources is used as torque
reference 1.
Configures the selection between torque references 1 and 2.
See diagram at 26.11 Torque ref1
0 = Torque reference 1

1.
Torque reference 1 is used when external control location
EXT1 is active. Torque reference 2 is used when external
control location EXT2 is active.

Defines the scaling factor for the torque reference (the torque
reference is multiplied by the value).
This allows drives sharing the load between two motors on the
same mechanical plant to be tailored to share the correct
amount each, yet use the same master torque reference.
Torque reference scaling factor.
Selects the source of torque reference additive 1.
Note: For safety reasons, the additive is not applied when an
emergency stop is active.
See the control chain diagram on page 581.
