This section contains general information pertaining to power supply
selection for use with the IB drive. See the section in Part II of this
document titled for the specific model IB drive you purchased for power
supply specifications and recommendations. Precise wiring and connection
details are to be found in Section 1.5,

Interfacing to the IB Series Driver

. The

following is covered by this section:

Proper selection of a power supply to be used in a motion system is as
important as selecting the drive itself. When choosing a power supply for a
stepping motor driver there are several performance issues that must be
addressed. An undersized power supply can lead to poor performance and
possibly even damage to your drive.

T h e P o w e r S u p p l y - M o t o r R e l a t i o n s h i p

Motor windings can be basically viewed as inductors. Winding resistance
and inductance result in an L/R time constant that resists the change in
current. To effectively manipulate the rate of charge, the voltage applied is
increased. When traveling at high speeds, there is less time between steps
to reach current. The point where the rate of commutation does not allow
the driver to reach full current is referred to as voltage mode. Ideally you
want to be in current mode, which is when the drive is achieving the
desired current between steps. Simply stated, a higher voltage will decrease
the time it takes to charge the coil, and therefore will allow for higher
torque at higher speeds.

Another characteristic of all motors is back EMF. Back EMF is a source of
current that can push the output of a power supply beyond the maximum
operating voltage of the driver and, as a result, could damage the stepper
driver over a period of time.
