11.2.1 Chopping frequency
A chopping mode is employed for the output to drive the motor on a constant current.
The chopping frequency that is the reference of the output can be changed with data, so that the PWM output does
not interfere with the other signals.
The chopping frequency can be set in a range of 40 to 250 kHz by the data of D0 to D5.
The set chopping frequency is used for output when executing stepping motor and constant-current driving.
<Output in accordance with set chopping frequency>
For constant-current driving with stepping motor (ch1 to ch4)
For constant-current driving (ch3, ch4, ch7)
Refer to the following table for the set value.
