5.4.3 Changing the follow ratio
The rate at which an axis follows the master can be adjusted, using a ‘software gearbox’. In the program, switches 2
and 3 can be used to set the ratio of the software gearbox, as described in Table 3:
Ratio
(Bit pattern sum)
Input switch 2
(Bit pattern value: 1)
Input switch 3
(Bit pattern value: 2)
1 Off Off
2 On Off
3 Off On
4 On On
Table 3 - Ratio selection using digital inputs
1. Confirm that input switches 2 and 3 are in the off position.
2. Set input switch 1 to the off position, to follow the Master Encoder.
3. Rotate the Master Encoder to confirm that for one turn of the Master Encoder, the motor completes one turn.
4. Now set input switch 2 to the on position to select a ratio of 2.
For one turn of the encoder, the motor now completes two turns.
5. Try different combinations of input switches 2 and 3 to select different ratios.
Note: An additional function is included in the program. When input switch 5 is set to the on position, Event IN5
is triggered, which disables following.
