Product Description:

The 5240-006 indexer driver is produced by Kollmorgen as part of the 5000 Indexer Drivers series. The unit coordinates stepper motor positioning sequences by generating and amplifying pulse trains while managing serial communication with a host controller. In automated assembly lines or material-handling stations, it translates higher-level motion commands into phase currents that advance the motor rotor by discrete increments. This arrangement lets the driver execute repeatable index moves and dwell periods without constant intervention from the external control system.

Internally, the driver regulates phase power with a fixed chopper frequency of 17 kHz, applying pulse-width modulation across a DC bus held at 35 Vdc. When energized from a single-phase supply of 115 VAC at 60 Hz, it draws 1 A of line current and supports an output of 2.5 A/phase to the motor coils, while idle current falls to 1.25 A/phase after motion stops. A current-reduction delay of 0.1 s separates active stepping from idle mode so holding torque is not reduced too early. Command data enter the unit through an RS-232 link that initializes at 9600 baud. Pulse generation supports two stepping modes, giving the controller a practical way to balance positioning resolution and motion smoothness.

The internal sequencer accepts up to 10000 steps/s, stores program variables in a nonvolatile block of 256 bytes, and offers 27 programmable instructions for motion, timing, and I/O branching. Position granularity equals 200 steps/rev in full-step mode or 400 steps per revolution when half-stepping is selected, enabling finer indexing without an external encoder. Five user-assignable I/O ports support start, limit, or handshake signals, allowing the driver to respond directly to machine-state inputs. The retained memory area keeps operating values available after power is removed, and the instruction set supports short standalone move sequences between serial updates.
