Rms current and peak current

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.

Additional Tips
Mathematics 32bit
The maths blocks present in the DS30 and DS5x stepper motor drives allow to execute multiplication, divisions, subtraction and sums at 32bit with sign.

The operands can be motion control registers, I/O registers, user's variables or constants»read more

User variables from 8bit to 32bit
The programmable stepper motor drives belonging to the DS30 and DS5x series allow to freely declare variables with sign with dimension between 1byte and 4byte.

In the DS5x drives these variables can be read or written through the Modbus-RTU»read more
