Rms current and peak current (9/5/2011)

For the stepper motor drives belonging to the xS10, DS30 and DS5x series the phase current is expressed in Arms, i.e. effective current. Instead, other manufacturers characterize their products indicating the peak current (sometimes also referred to as maximum current- Imax) and this does not allow to get the maximum torque from the motor.

The rms value of a sinusoidal current is equivalent to 1,41 times the peak current (about 40% more) therefore, for example, a drive used in microstepping and calibrated for a phase current amounting to 5Arms is equivalent to a drive by 7,05A of peak.

Fast optocouplers
The stepper motor drives beloging to the DS10, LS10 and OS10 series are equipped with fast optocouplers which allow to apply step frequencies of more than 300KHz.»read more
Innovative digital inputs
All the digital inputs present in the stepper motor drives of the xS10, DS30 and DS5x series are optoisolated.

Each optocoupler has an innovative current limiting circuit that allows to supply each input singularly, and independently one from the»read more

Interrupted phase alarm
The stepper motor drives of the xS10, DS30 and DS5x series implement a special technology able to detect the interrupted phase condition.

This characteristic, hard to find in other drives, is particularly useful when the motor is used in open loop»read more

Line Driver inputs
All the input digital lines of the stepper motor drives belonging to the xS10, DS30 and DS5x series can be controlled also in differential mode (also known as Line Driver).»read more
