TECHNICAL CHARACTERISTICS
|
Supply voltage
|
Power stage: min. 12Vdc max 40Vdc.
Logic: 12Vcc +5%.
|
Phase current
|
Settable continuosly by means of a potentiometer.
Externally selectable at 30%, 60% and 100% of the nominal current.
Up to 1.7 A/phase.
|
Resolution
|
HALF or FULL step selectable by means of an external signal.
|
Motor types
|
For stepper motor with 4,6 or 8
windings in serial or parallel mode.
|
Oscillator
|
Optional module, to generate step pulses with
acceleration and deceleration ramps.
|
Inputs
|
All inputs are compatible with standard TTL or CMOS.
|
DIRECTION input
|
When this input is activated, the motor direction is reversed.
|
STEP input
|
Minimum pulse width: 10us
Maximum frequency: 50KHz.
|
ENABLE input
|
Optically insulated direction input.
This input enables the driver output stage and, when disabled, the motor is deenergized.
|
RESET input
|
When activated, this input reset the motor windings to the default state.
