5.5.2 - Explanation of parameters in menu 4
04.01 : Current magnitude
Adjustment range : 0.00 to 2.22 x 11.32 (A)
Format: 32 bits
Reading of the rms current in each drive output phase.
This is the result of the vectorial sum of the magnetising current
and the active current.
Note: Max. drive current = 2.22 x 11.32 .
04.02 : Active current
Adjustment range : ± 2.22 x 11.32
Format: 32 bits
Reading of the active current delivered by the drive.
The active current gives a fairly precise image of the motor
torque between 10 Hz and 50 Hz.
A negative value indicates operation in generator mode with
driving load whereas a positive value indicates operation in
motor mode.
04.03 : Torque demand
Adjustment range : ± 999.9%
Format: 16 bits
Value of the torque demand required by the motor as a % of the
rated motor torque.
04.04 : Active current demand
Adjustment range : ± 999.9%
Format: 16 bits
The current demand is the result of conversion of the torque
reference 04.08 into active current.
04.04 = 04.03 when the drive current limit is not reached and
the motor is not in the defluxing zone.
04.05 : Motoring current limit
Adjustment range : 0.0 to 300.0% (% motor active In)
Factory setting : 150.0% In
Format: 16 bits
Used to set the maximum starting current limit permitted in
motor mode during a maximum time specified by 04.51 .
When the value of 04.05 is less than 04.07 , then 04.05
overrides 04.07 .
04.06 : Regenerating current limit
Adjustment range : 0.0 to 300.0% (% motor active In)
Factory setting : 110.0% In
Format: 16 bits
Used to set the maximum permanent current limit permitted in
generator mode.
04.07 : Symmetric current limit
Adjustment range :0.0 to 300.0% (% motor active In)
Factory setting : 110.0%
Format: 16 bits
Used to set the maximum permanent current limit permitted in
motor mode and in generator mode.
Note:
If 11.31 is set to «Induction motor in open loop mode» (1) and
05.14 is set to «None: Linear U/F law with boost» (2) or
«None: Square U/F law with boost» (5), the only current limit is
then defined by 04.07 .
04.08 : Torque reference
Adjustment range : ± 04.24 (% motor active In)
Factory setting : 0.0% In
Format: 16 bits
Main torque reference when the drive is configured for torque
control.
Give a positive reference for the torque to be applied clockwise
and conversely, a negative reference for the torque to be
applied counter-clockwise.
The maximum value of 04.08 is fixed by 04.24 .
04.09 : Torque offset
Adjustment range : ± 150.0%
Factory setting : 0.0%
Format: 16 bits
04.10 : Torque offset selection
Adjustment range : No (0) or Yes (1)
Factory setting : No (0)
Format: 8 bits
No (0):
The torque reference equals parameter 04.08 .
Yes (1):
The torque reference equals parameter 04.08 plus the torque
offset value 04.09 .
