• When pulses are input, the motor rotates one step as the pulses
start (pulse fall).
• The voltage of the pulse signal is ON: +4.5 to +5.5V, OFF: 0 to
+0.7V. Input-pulse signals should have a pulse width exceeding
1
µ
sec, pulse rise/fall below 1
µ
sec, and a pulse duty of less than
50%.
Driving motor current
The
D2D2043-S
can drive motors with a rated current of up to
4.38A/phase. However, we recommend you follow the drive
conditions below in view of the rating of internal heat generation
(which affects product life).
(Running current)
2
× X + (Standstill current)
2
× (1 - X) < 7.5
X: Motor’s operating duty relative to operation time
Example) If the motor is used at an operating duty of 100% or
standstill current of 100%, the running current will be
2.12A/phase or less.
Setting
Step resolution
Use this function when you want to reduce vibration and noise, or to
change the motor speed or feed rate without changing the input pulse
speed.
