Measurement
In the following the range from the input terminals of the interface card up to the as
setpoint value or actual value analyzable speeds and frequencies is referred to as
speed measurement. Fig. 1 shows the signal flow and the intervention possibilities of
the speed measurement.

Fig. 6.10.6.a Summary of speed measurement
Central parameter of the speed measurement is dr.24. This parameter must be adjusted
according to the installed interface card.
Value bit 0 bit 1,2 Channel 1 Channel 2
0 0 0 no detection no detection
1 1 0 Incremental encoder input 1 no detection
2 0 1 no detection Tacho input (±10V input)
3 1 1 Incremental encoder input 1 Tacho input (±10V input)
4 0 2 no detection Incremental encoder input 2
5 1 2 Incremental encoder input 1 Incremental encoder input2
6 0 3 no detection Initiator input
7 1 3 Incremental encoder input 1 Initiator input
Defintion of the Hardware
Attention, adjust motor data !
The inverter gets the pole pair number (PPN)
from dr.3 / dr.1 * 60 (also see chap. 6.6.3)
Don’t forget, 4 poles = 2 pole pairs !
