Set integral component
To enter defined starting values for the torque, the integral component of the n-controller can be set
externally (e.g. when using the brake control).
•
MCTRL_bILoad_b
= TRUE
– The n-controller accepts the value at
MCTRL_nISet_a
for its integral component.
– The value at
MCTRL_nISet_a
acts as a torque setpoint for the motor control.
•
MCTRL_bILoad_b
= FALSE
– Function is switched off.
2.12.8
Torque control with speed limitation
Set
MCTRL_bNMSwt_b
= TRUE to activate this function.
•
A second speed controller (auxiliary speed controller) is connected to ensure speed limitation.
•
MCTRL_nMAdd_a
acts as a bipolar torque setpoint.
•
n-controller 1 generates the upper speed limit.
– The upper speed limit is given at
MCTRL_nNSet_a
in [% ] of n
max
(pos. sign for CW rotation).
•
n-controller 2 (auxiliary speed controller) generates the min. speed limit.
– The min. speed limit is given at
MCTRL_nNStartLim_a
in [% ] of n
max
(neg. sign for CCW direction of rotation).
•
n
max
is selected under C0011.
Stop!
Use
•
the max. speed limit for CW rotation (pos. values) and
•
the min. speed limit for CCW rotation (neg. values),
otherwise the drive can accelerate in an uncontrolled wa.!
