Parameter Type Function
Frequency MI,
ML,
DW
Note that F=1/T, where T is the duration time of a complete cycle.
Frequency settings differ from npn to pnp output type.
• npn: You can use a value of 0, or a value from 8-50000Hz (
50kHz).
• pnp: You can use a value of 0, or a value from 8-2000HZ.
Other frequency values are not supported.
Duty Cycle MI,
ML,
DW
The ratio of the "on" period of a cycle to the total cycle period. This
value may be from 0-1000, and is expressed as a percentage.
If, for example, the constant 750 is stored into the Duty Cycle operand,
the duty cycle is equal to 75.0% This means that the pulse will hold a
positive state during 75.0% of the total cycle.
In the figure below, MI 22 Duty Cycle Value is equal to 250. This
results in the duty cycle being 25% of the total cycle time.
If values out of range enter the Duty Cycle and Frequency operands,
the output turns OFF and remains OFF until the values re-enter the
range.
Run MB Changes the operating mode of the output from normal output mode to
HSO mode:
0 (SET)=Normal Mode, 1 (RESET): HSO Mode.
Current
Position
DW This is the current location of the stepper.
Target DW This is the location you want the stepper to move to.
