 TECHNICAL CHARACTERISTICS
Supply voltage
Nominal value 70V (allowed from 24V to 85V).

Phase current
Selectable by means of a dip switch from 2A to 10A in 8 steps.
By an external signal it is possible to reduce the current to 50% of nominal value.

Automatic current reduction
If activated, 200ms after the last step, the nominal is reduced to 50% of the nominal value.

Resolution
Full, half and quarter step mode are selectable by means of a dip-switch.

Motor types
4, 6 or 8 wires stepper motors can be serial or parallel connected.

Closed loop operation
(*)
With an optional module, is possible to use an external incremental encoder to close the position or the velocity loop.

Micro-step

Up to 256 microstep using an optional plug-in module (up to 51,200 steps/rev).

DIRECTION input
When this input is activated, the motor direction is reversed.

Input / Output
Optical isolation for noisy environments.

STEP input
Minimum pulse width: 1us.
Maximum frequency: 500kHz.

ENABLE input
If this input is activated, the motor is disabled.

CURRENT REDUCTION /
BOOST input

If activated the current in the motor is incremented/reduced by 50%.

FAULT output
Open collector output, low level active (50mA, 30V).
