1 FEATURES
• NEMA Size 23, 2 Phase, 1.8° Bipolar Step Motor w/ Built-In Microstepping Driver
• Operates from +12 to 48 VDC with certain currents *
• Selectable phase currents from 0.3 to 3.0 Amp Peak with certain voltages *
• Selectable hold currents of 0%, 25%, 50%, or 100% of the run current
• Step Resolutions from Half Step to 256x Microstepping
• Four Selectable Damping modes (Fast decay, 17%, 37%, Slow decay)
• Disable Power feature to hold after disabling unit and inhibit stepping or to power off
motor after disabling unit and inhibit stepping.
• Step and Direction sensing on the rising or falling edge of step pulse input
• Smooth motion
• Three optically isolated control inputs
• Pole Damping Technology™ integrated within driver board
*The IMD23 can handle a 24VDC and 3 Amp system OR a 48VDC and 2 Amp
system
Pole Damping Technology™
Pole Damping Technology™ (PDT) enhances step motor performance by dampening each
full step in order to create a more accurate and smooth motion profile. Microstepping the
step motor will optimize Pole Damping Technology™. PDT outputs the correct amount of
run and hold currents to the motor, at the right time. Thus, it will overcome the step
motor’s natural tendency to want to forcefully pull towards the full step ON position.
