(Electronic Damping) Dip switch setting for range of load-to-motor inertia ratio. Dip switch for automatically rotating step motor back and forth. SELF TEST Useful for testing motor and power supply connections. Performs high resolution stepping by synthesizing fine microsteps from coarse steps. MICROSTEP EMULATION Available with full (200 SMOOTH) and half (400 SMOOTH) step resolutions. 5-24V, optically isolated, sinking (STR2) or differential (STR4/8). Minimum pulse width = 250 ns. Maximum pulse STEP INPUT frequency = 150 kHz or 2 MHz, user selectable. Function = step or CW pulse. DIRECTION INPUT 5-24V, optically isolated, sinking (STR2) or differential (STR4/8). Minimum pulse width = 250 ns. Maximum pulse frequency = 150 kHz or 2 MHz, user selectable. Function = direction or CCW pulse. 5-24V, optically isolated, sinking (STR2) or differential (STR4/8). Function = disable motor when closed. ENABLE INPUT 30V/80mA max, optically isolated, sinking or sourcing. Function = closes on drive fault.
