Description
Selects the source of the positive speed enable command.
1 = Positive speed enabled.
0 = Positive speed interpreted as zero speed reference. In the
figure below, 23.01 Speed ref ramp input
the positive speed enable signal has cleared.
Actions in different control modes:
Speed control: Speed reference is set to zero and the motor is
stopped along the currently active deceleration ramp. The
rush controller prevents additional torque terms from running
the motor in the positive direction.
Torque control: The rush controller monitors the rotation
direction of the motor.
Example: The motor is rotating in the forward direction. To
stop the motor, the positive speed enable signal is
deactivated by a hardware limit switch (e.g. via digital input).
If the positive speed enable signal remains deactivated and
the negative speed enable signal is active, only reverse
rotation of the motor is allowed.
