Five-phase stepper driver

The Autonics MD5-ND14 is a bipolar constant-current driver for five-phase stepper motors. It operates from a 20-35VDC supply and delivers up to 1.5A per phase. Two step resolutions are available: full step and half step.

Automation and motion control builds

Engineers building CNC machines, precision positioning stages or laboratory automation will find the five-phase topology and selectable resolution useful. Buyers who need microstepping beyond half step or a different phase count should look at other driver types.

1.5A per phase current rating

The maximum run current of 1.5A per phase determines whether the driver can power your chosen motor without overheating. Match this figure to the motor's rated current per phase before purchase.

Questions about this item

What power-supply voltage range does the MD5-ND14 driver require?

The driver operates from a 20-35 VDC supply, so the source must stay within that window for reliable operation.

How is the motor current set on this 5-phase driver?

The driver runs at a fixed 1.5 A per phase; there is no external potentiometer, so the motor must be rated for that current.

Which wearing parts should be kept as spares for the MD5-ND14?

The unit has no user-replaceable fuses or fans; plan to replace the whole driver if it fails after the 3-year parts coverage.
