3.5 Stepper motor driver IC interface
3.5.1 Output pulse specification
OUT and DIR output signals of PCL6115 are connected to CK and CW/CCW input signals of the stepping motor
driver IC (TB6608FNG).

The output pulse specification (PMD2 to 0) of the environment setting 1 register (RENV1) of PCL6115 is 0x02.
3.5.2 Excitation setting method
P3 and P4 general-purpose output signals of PCL6115 are connected to M2 and M1 input signals of stepping
motor driver IC (TB6608FNG). The following shows the maximum speed and movement amount of one rotation
when connecting to the stepping motor PFCU30-24V4GM (1/12).

The default setting is 2W1-2 phase excitation mode. The setting contents can be checked with sub status
(SSTSW) of PCL6115.
3.5.3 Action mode
P5, P6, and P7 general-purpose output signals of PCL6115 are connected to STBY, RESET and
ENABLE input signals of stepping motor driver IC (TB6608FNG).
