 STP300D

The STP300D, stepper driver, is specially indicated for driving stepper motors in high performances applications.

Operating voltage from 12 to 48Vdc and with a nominal phase current up to 3A in 8 equally spaced levels by dipswitch selection.

Analogic input for automatic step generation.

The STP300D stepper driver board is modular and compact and uses the last generation soluctions to reach the maximum performances and reliability.

The board can be equipped and connected with a wide range of accessories and controls to build a fully customized stepper systems.

 TECHNICAL CHARACTERISTICS
Supply voltage
12 ÷ 48Vdc

Phase current
From 400mA to 3A in 8 equally spaced steps by changing the dipswitch.

Current reduction
The nominal phase current is automatically reduced by 50% after 200ms from the last step received.

Resolution
Full, half and quarter step resolution available.

Motor types
For stepper motor with 4,6 or 8 windings in serial or parallel mode.
Configurable for high and low inductance motors.

DIRECTION input
Optically insulated direction input. This input selects the CCW or CW rotation mode.

Clock input
Minimum width: 7us
Maximu step rate: 50KHz.

ENABLE input
(All windings off)
Optically insulated input.
This input enables the driver output stage and, when disabled, the motor is de-energized.

FAULT output
Open collector output, active low, used to signla the working condition to a PC or PLC
(max 50mA, 30Vcc).

Plugin modules
(optional)
Oscillator
Indexer with serial interface RS232 and RS485

NOTE: This driver can be shipped with custom cycles built-in without additional costs, please contact factory for informations.
