TA "Actuator – torque"
When the technology application "actuator – torque" is used the drive creates a torque to
be specified independent of the motor speed. A superimposed speed limitation prevents
the drive from accelerating in an uncontrolled mode. The torque setpoint and torque limit
value are the main setpoint values of the application.
r
The setpoint of the motor torque can be specified for both directions. The drive
accordingly acts in a driving or braking way. With a unipolar setpoint the effective
direction can be changed via the digital input DI3.
r
After the enable of the torque-controlled operation via the digital input DI2 the
creation of the torque is controlled via a ramp generator starting from the current
torque.
r
The torque limit value to be specified refers to the freely setting direction of rotation
with positive torque. Based on the current motor speed the internal speed limit value
is also led to the setpoint via a ramp generator after enable.
r
If the specified speed limit value directly corresponds to the line speed, the internal
limit value can be increased by entering an offset in C03008.
r
The speed limit value in negative direction of rotation equals, according to amount, the
limit value for the positive direction of rotation.
r
If the speed of the drive is inside the limitations, the motor generates the specified
torque.
r
If the positive or negative speed limit value (for CW or CCW rotation) is reached, the
drive changes to the speed-controlled operation. The set speed limit values are not
exceeded.
Basic drive functions
r
A quick stop can be activated via the digital input DI1.
r
A manual control is provided for the setting-up operation. It is enabled via the digital
input DI6. The inputs DI7 and DI8 activate parameterisable setpoints for both
r
The basic function "limiter" enables the travel range to be monitored via limit switches.
r
When a brake is available the brake control opens and closes the brake.
