TECHNICAL CHARACTERISTICS
|
Supply voltage
|
-70: Nominal value 70V (allowed from 24V to 85V).
-120: Nominal value 120V (allowed from 24V to 160V).
|
Phase current
|
Selectable by means of a dip switch from 1.6A to 6.5A 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).
