Product Description:

The P70530-PNN is a stepper motor drive manufactured by Kollmorgen and supplied in the P7000 Stepper Drives series. It interfaces between a DC power bus and a two-phase stepper motor. The unit provides microstepped current regulation for positioning tasks in industrial automation and is intended for applications that need controlled indexing without a separate feedback device.

The drive accepts an input range of 20–75 VDC, allowing it to share power supplies used by medium-power motion axes. During operation, it can deliver a continuous phase current of 5 A rms and momentary microstep peaks up to 7.1 A peak. The internal bus triggers an overvoltage fault at 91 VDC and an undervoltage fault at 18 VDC, while inrush current is limited to 15 A for 4 ms by a 10 A slow-blow fuse. Control pulses enter through the Step input with a maximum frequency of 2 MHz, and the minimum on and off time is 800 ns while the direction line must remain stable 50 µs before the first edge. Idle current can be reduced from 0 to 100 percent to help keep the chassis below its 70 °C limit when ambient temperature is between 0 and 45 °C. Internally, the drive draws 50 mA for logic, and the housing measures 29 × 111 × 107 mm for compact control panel installation.

Logic resources include nine optically isolated programmable inputs rated for 5–24 VDC, four dedicated ±Enable and ±Step/Dir lines at 5 VDC TTL, and a general-purpose output that can switch 30 VDC. Up to 63 programmed moves are stored locally, selected through six bits, and executed with Motion Node indexing. Resolution is adjustable from 200–50,000 steps per revolution, supporting speeds from 0–50 revolutions per second and mechanical power up to 300 W. Communication with a host occurs over RS-232 at 19,200 baud. The drive supports NEMA 17, 23, 34, and 42 frame motors with inductances from 2 to 15 mH, is intended for DC models only, and uses a fixed feature set without optional plug-in boards.
