Figure 4: Encoder quadrature signals and motor
commutation signals.
iC-PT H-series devices determine the optical radius
and the native cycles per revolution for the quadrature
outputs by its phased array design.
The U, V, W commutation signals can be configured
independently of the device: the pulse count, period
length and phase shift is determined by the code disc.
Standard code discs available for sampling provide 4
CPR each for U/V/W, with a period length of 90 de-
grees (C). A phase shift of 0 degrees (ϕ) between U
and Z edges must be considered during alignment.
Ideally, the rising edge of U meets the index Z.
For detailed specifications, refer to the relevant code
disc datasheets, available separately.

Figure 6: Example of analog ABZ / digital UVW
(pin SEL = 75% VCC)
The iC-PT H-series features 5 principle operation
modes which are selectable by the voltage applied to
pin SEL. A voltage divider as suggested by Table 4 is
the easiest way to obtain this.

Table 4: Selection of operation mode by pin SEL.
If input SEL is left open, the IC biases its input at
50% VCC and analog output signals are available for
test and alignment.
Analog output signals may also be used to increase
the encoder’s resolution by connecting an external in-
terpolation IC. In this case the analog signals are re-
quired permanently, so that noise immunity should be
improved by wiring pin SEL to an external reference
providing VCC/2.
Setting 75 % VCC may be considered to obtain ana-
log signals at PA/PB/PZ and NA/NB/NZ outputs feed-
ing the external interpolation IC, together with digital
signals at U/V/W directly connecting a line driver. Spe-
cial attention to the PCB layout should be paid to avoid
cross talk; analog and digital lines should be separated
carefully.
