Operating modes
Parameters
CFC & M-control
CFC & M-control (only with MCV, MCH) in parameter set 1 only.
This operating mode enables the asynchronous motor to be controlled directly with
torque control. The setpoint is standardized on the torque as follows:
3000 1/min = 150 % output current × torque constant.
In P16x Fixed setpoints 1 you can enter the torque values directly in [% I
N
]. If setpoints
are entered via analog input, the set processing P11x Analog input AI1 applies to torque
control as well.
The torque constant (motor-specific value) is defined with: k
T
= M
N
/ I
q_n
Setting the parameter P820 4-quadrant operation 1 will be ignored; 4-quadrant opera-
tion is always active.
NOTES
•
If P500 Speed monitoring 1 is active, the drive is monitored according to parameter
description P500.
•
If P500 Speed monitoring 1 set to OFF, the drive reacts as follows when exceeding
or falling below P302 Maximum speed 1 :
– Motor operation: The available motor torque is reduced to zero with a linear func-
tion above n
max
and below –n
max
. There is no active speed control.
– Regenerative operation: No response; the master drive must prevent the drive
losing position.
•
M-control is also in effect in the range –n
min
... n ... n
min
.
•
The current is always limited to P303 Current limit 1.
