Parameters 281
Selects a mathematical function between the reference
sources selected by parameters
. See diagram at
Ref1
Signal selected by
is used as torque
reference 1 as such (no function applied).
0
Add (ref1 + ref2)
The sum of the reference sources is used as torque reference
1.
1
Sub (ref1 - ref2)
The subtraction ([
] - [
]) of the reference sources is used as torque
reference 1.
2
Mul (ref1 × ref2)
The multiplication of the reference sources is used as torque
reference 1.
3
Min (ref1, ref2)
The smaller of the reference sources is used as torque
reference 1.
4
Max (ref1, ref2)
The greater of the reference sources is used as torque
reference 1.
5
Configures the selection between torque references 1 and 2.
See diagram at
.
0 = Torque reference 1
1 = Torque reference 2
Torque reference 1
0.
0
Torque reference 2
1.
1
Follow Ext1/Ext2
selection
Torque reference 1 is used when external control location
EXT1 is active. Torque reference 2 is used when external
control location EXT2 is active.

8
). -
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.
1.000
-8.000 … 8.000
Torque reference scaling factor.
1000 = 1
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
For the selections, see parameter
.
Defines a low-pass filter time constant for the torque
reference.
0.000 s
0.000 … 30.000 s
Filter time constant for torque reference.
1000 = 1 s
No.
