1.5.6
Positioning
Positioning is achieved through the NC control system with position rule capture via
encoder. In the positioned condition the cam is stopped play-free by an electric
brake. In the event of high tangential forces, a hydraulic table top clamping can be
used (greater rigidity, relief of the gearbox parts).
1.5.7
Drive motors
As standard, three-phase servo motors are used as drive motors. Direct current or
hydraulic servo motors can also be used. For individual cases with low precision
requirement the use of three-phase standard motors in conjunction with a frequency
converter is possible.
1.5.8
Reference point
The rotary table can, as an option, be equipped with a fixed reference point switch.
The measuring system is set to this. The switch is used to reduce the speed and has
a signal length of approx. 3-4°. The switch is operated in the zero position. The
start-up of the reference point switch can be performed with a clockwise (CW) and a
counter-clockwise (CCW) direction of rotation.
1.5.9
Holding brake
The holding brake is energised to stop the worm shaft. Voltage 24 VDC
The operation is performed from the motor via spur wheel transmission to a worm,
which drives the table top via rollers. Positioning is achieved through an NC control
system with position rule capture via a corresponding measuring system. In the
positioned condition the worm shaft is stopped play-free by the holding brake.
If the solenoid [1] is switched on the dotted magnetic field is depicted. The anchor
plate [3] is pressed onto the braking coil carrier with friction lining [4]. The shaft is
braked. The brake torque runs from the coil carrier [3] via the friction lining [4],
anchor plate [3] and membrane transmission spring [5] to the flange [6] and the
shaft.
If the solenoid [1] is de-energised, the membrane transmission spring [5] pulls the
anchor plate [3] away from the coil carrier [1]. The shaft can run through freely.
