5.1
Setting up the motor current
The current supplied to each of the step motor’s phases can be adjusted for standby and
running currents by changing the values of standby and running currents under “Driver
parameters” in the MacTalk program. The register is also accessible in general through
the serial interface.
The electronics automatically switches between the two currents by detecting the pres-
ence of step-pulses. If a rising edge is detected at the step-clock, the “Move current” is
selected. If no rising edge is detected during the period specified by “Standby time” at
the step-clock input, the current is automatically switched back to “Standby current”.
Values for the two currents are typically adjusted so that the Operating Current is signif-
icantly higher than the Standby Current, since the motor must be supplied with more
power to drive its load during acceleration and constant operation than when it is sta-
tionary.
5.1.1
Standby current considerations
The main reason for having the Standby current setting is to optimise the heat produced
by the motor.
Having a suitable standby current will make sure that the motor do no loose position but
also make sure that the motor is not producing more heat than necessary.
A typical setting of the Standby Current typically is 30-40% of the Running current.
Normally the motor do not need to produce any significant torque during standby and
therefore it makes sense to lower the standby current.
