This feature allows the user to
rapidly move long distances, yet
precisely position the motor at the
end of travel without the expense of
high performance controllers.
The development of proprietary cir-
cuits has minimized ripple cur rent,
while main tain ing a 20 kHz chopping
rate. This prevents additional motor
heating that is common with drivers
requiring higher chopping rates. Now
low in duc tance stepper motors can
be used to improve high speed per-
for mance and system ef cien cy.
The IM1007 also comes with an
optional on-board indexer to provide
design engineers with ver sa til i ty
and power unmatched in today’s
in dus try.
The IM1007 is priced lower to
provide customers with af ford able
state-of-the-art technology for that
competitive edge needed in today’s
market.
DESCRIPTION
The IM1007 is a high per for mance,
low cost microstepping driver that
in cor po rates advanced surface
mount and ASIC tech nol o gy. The
IM1007 is small, easy to interface
and use, yet powerful enough to
handle the most de mand ing ap pli -
ca tions.
The IM1007 has 14 different
resolutions (both in binary and
decimal) built into the driver. These
resolutions can be changed at any
time. There is no need to reset the
driver.
