ADH42 Stepper Motor Controller (Spontaneous Pulse)
Product Link
[edit]Description
[edit]The ADH42 is a spontaneous pulse stepper motor driver with a form factor of 42mm x 42mm x 21.5mm, designed for NEMA17 integrated stepper motors.
Built with a 32-bit digital chip, it supports standard pulse and direction mode and spontaneous pulse mode. In spontaneous pulse mode, the motor rotates instantly when power is applied at a DIP-switch-set speed.
The driver operates on 12-40VDC with 24VDC recommended, delivering 1.4A continuous and 2.1A peak. Step pulse frequency reaches 200KHz. Protection includes over-voltage, under-voltage, and over-current. An alarm output provides fault indication.
