Operating modes
The incomplete machine can be operated in the following modes:
•
Normal mode
o
Intermittent mode
o
Continuous mode
o
Reverse operation (oscillating operation)
•
Jog mode
•
Emergency stop
NOTICE
Damage to the incomplete machine without electronic control!
Improper control of the incomplete machine can result in substantial damage to property.
No jog mode may be operated without a suitable universal control unit (TIC).
Use a suitable universal control unit (TIC).
3.3.1
Normal mode
By normal operation we mean the cycling of the indexing ring / output flange in one direction from one position to
the next. The direction of rotation of the indexing ring / output flange is determined by the direction of rotation of
the drive. This can easily be reversed in the case of the three-phase motor by swapping two phases of the supply
voltage.
3.3.2
Intermittent mode
The drive shaft stops in the cogging phase of the drum cam. The step time is fixed. The cogging time is variable.
This operating mode is used in systems with much longer machining times than turning times and is the most
common operating mode.
3.3.3
Continuous mode
The incomplete machine runs continuously without motor stop. Step and cogging times are fixed
and are run through evenly. The drive motor has only one direction of rotation.
This operating mode is often used in fast-running systems with short machining times. The
incomplete machine is mechanically synchronized to the rest of the system via the free drive shaft.
The ratio between cogging and stepping time can be adjusted within certain limits by TAKTOMAT
during cam production.
3.3.4
Reverse operation (oscillating operation)
Reversing operation (pendulum operation) The drive of the incomplete machine is reversed in each
case during the cogging phase.
3.3.5
Jog mode
The indexing ring / output flange constantly oscillates back and forth between two positions in this operating
mode. The drum cam cannot smoothly accelerate and brake the built-up load.
This represents a stress situation for the mechanical system, since the accelerations occurring during jog
mode exceed those of normal operation many times over. Jog mode may only be operated with a suitable
universal controller (TIC).
3.3.6
Emergency stop
The emergency stop is comparable to stopping in jog mode. Here too, the stopping and restarting of the established
load takes place outside the cogging phase. Frequent emergency stop situations must be avoided.
