TECO A510s - PG and Motor Rotation Direction; Motor Operation Direction; PG Operation Direction; PG Pulse Dividing Ratio

4-293
20-28=0: Forward operation, phase A is leading (phase B is leading for reversal operation).
20-28=1: Forward operation, phase B is leading (phase A is leading for reversal operation).
Figure 4.4.118 PG and motor rotation direction
Motor direction is determined as below:
Forward: The motor direction is counter-clockwise when inverter runs in forward direction (see figure 4.4.119.)
Figure 4.4.119 Motor operation direction
Forward: The motor direction is clockwise when inverter runs in forward direction (see figure 4.4.120.)
Refer to the below figure 4.4.120 for PG feedback pulses.

(6) PG pulse dividing ratio (20-29)
Sets the pulse divider ratio between the PG input and PG output.
The left most digit (3
rd
) represent the numerator and the last to represent the denominator.
Ratio is calculated as follows:
20-29= □ □□, = n kk
Range n: 0 to 1
Range k: 1 to 32
Ratio = (1+n)/k
