It is an initial position in each excitation mode when the counter is reset the state in the early starting up the power supply.

A standard voltage for the current the setting and the standard voltage output current setting can be switched to four
stages by the serial data.
It is effective for the power saving when the motor energizes maintenance.
(Computational method of set current value)
A standard voltage can set the output current from the RF resistance connected between standard voltage and
terminal RF-GND because it is changeability can (0.2V,0.140V,0.1V,0.060V) in the serial data.
IOUT = (Standard voltage x Set current ratio) / RF resistance
(example)The following output current flows in 100% and the RF resistance 1 compared with 0.2V in a standard
voltage and set currents at times.
IOUT = 0.2V × 100% / 1 = 200mA
Chopping frequency setting
The oscillation circuit is built into in IC, and the chopping frequency of the constant current control can be switched by
setting serial data 0110, D4, D5, and ***.
