Electrical connection, gearchange 

The gearbox is electrically connected using the 
supplied 8-pole Harting connector (HAN 8 U). The 
plug-in connection is located on the shift unit.

The required cable lead diameter is 1.5 mm². 

The 24 V DC connection voltage and 5 A power 
consumption must be assured on the shift unit 
connector. 

Losses due to cable length and transition resistors 
must be taken into account. 

Scope of supply: 

Sleeve housing, screw connection, socket insert 
and 8 jacks, type Harting AWG16. The shift unit 
can only be obtained as a complete part. 

Gearbox shift mechanism: 

Gearchanges are effected when the 24 V voltage 
is applied to pin 2 and 3. The polarity of the  
applied 24 VDC voltage dictates which gear is 
engaged. 

In 1st gear 

 

=> Pin 2: + / Pin 3: 

 

In 2nd and 3rd gear 

=> Pin 2: 

 / Pin 3: + 

During the gearchange, the main spindle motor 
should make the shaft osc5° or -5° at a rate 
of 1 to 5 rotation direction changes per second. 
Major pendulum motion may lead to damage at 
the meshing gears. The gears usually already 
mesh at the first rotation direction change, so that 
the switchover time is approx. 300 to 400 ms. 

 

 

 

 

 

 

 
In average, this means: n

Mot

 = 5°/s = 5° 60/min = 

300°/min = 300/360 rpm = 0.83 rpm.

The machine optimum is to be determined on  
the basis of shift tests in relation to the different  
masses and thereto connected drag torques of  
the spindle. 

The limit switch signals of S1 – gear 1 (contact 4) 
and S2 – gear 2 (contact 6) serve to shut off the 
shift unit once the gearchange is complete.

  

 

CAUTION 
After the limit switch signals have been reached, 
the shift unit is allowed to be live for a maximum 
of 0.5 second. The limit switch signals must be 
monitored during the operating time. 

The limit switches must only be energized with 
the control current (0.1 – 0.5 A) and not with the 
changeover current (5 A).
