Brief description
2 Brief description
The technology application "actuator – speed" enables the drive to create a speed to be
defined. The speed setpoint can be complied with using a speed controller which adopts
the motor torque to the prevailing load situation.
r The speed setpoint of the drive can be specified for both directions. The driven machine
parts accordingly moves forwards or backwards. As an alternative to the inversion of
the setpoint, the change of the direction of movement can be done via the digital input
DI3.
r After the speed-controlled operation is enabled via the digital input DI2 the
acceleration/deceleration of the drive to the setpoint is controlled via a ramp generator
based on the current setpoint/actual speed.
r The maximum torque of the drive can also be controlled, if required.
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 digital inputs DI7 and DI8 activate parameterisable setpoints for both
directions of rotation.
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.
Application range
r General servo drive for speed control of:
– Conveyor drives (connected in one system)
– Extruders
– Test benches
– Vibrators
– Travelling drives
– Presses
– Machine tools
– Dosing machines
r Actuator for higher-level controllers
– Positioning drives with external position control
– Multi-axis systems with external path control
Required license/delivery
r Available in every license stage.
r The technology application is saved at program memory location 2 in the memory
module and can be selected from the »Engineer« application catalog.
