6410-001-N-N-N

6410-001-N-N-N is a Pacific Scientific drive in the 6410 Stepper Drives series. Its two-phase bipolar chopper circuit controls current through two motor phases, while the 20 kHz chopper frequency regulates phase current by rapid switching. The drive provides a peak phase current of 7.1 A and an RMS phase current of 5 A for operating a connected stepper motor. It accepts a supply voltage from 24 Vdc to a maximum of 75 Vdc, and an 83 Vdc bus-overvoltage fault threshold protects the drive by triggering a fault when the DC bus rises too high.

The step input supports frequencies up to 2.0 MHz for high-rate motion commands and requires a minimum pulse width of 250 ns for reliable detection. A direction setup time of 50 µs requires the direction signal to stabilize before a step command is received. The unit measures 5 inches in height, 1.5 inches in width, and 4.3 inches in depth, and it weighs 1 lb.
