OVERVIEW
The DR-4M is a high performance,
microstepping driver designed to meet
O.E.M. requirements for reliable, cost
effective operation. The DR-4MPS
provides the next level of user
integration with a built in 40 volt power
supply.
Both drivers offer eight resolution settings,
from 1/2 step to 1/256 step. They are
short circuit, over temperature and
under voltage protected for extended
service life. Features include:
Low cost - small size
Heatsinked enclosure
1 Mhz step clock
Integral power supply (DR-4MPS)
Step resolution to 50k steps/rev.
4 amp output current (Peak)
Auto current reduction/boost
Phase to phase/ground, over temp.
and under voltage protected
Fault and diagnostic indicators
Mating connectors included
CONTROL INPUT
The essential input signals include a
step pulse and direction control and
three resolution select lines to permit
remote setting of microstep size.
Inputs are TTL/CMOS compatible with
current limiting circuitry capable of
withstanding temporary over voltages.
A miniature eight contact RJ-45
connector is provided for convenient
interface of user control signals to the
driver. Available resolution settings
include from 400 to 51,200 steps per
revolution.
OUTPUT CURRENT
The DR-4M and DR-4MPS will
automatically increase and decrease
the current in the motor windings after
the completion of a move. A
convenient dip-switch, located on the
front panel, is used to set the hold and
run currents in 14% increments,
between 0 and the maximum setting.
On power up, the drivers are disabled.
On application of step pulses, the
programmed run current value is set.
POWER SUPPLY
The DR-4M driver can be operated
from a single unregulated DC power
supply. Maximum input voltage is 45
volts. Multiple drivers can also be
connected to a single power supply
source.
The DR-4MPS integrates a 40 volt (80
volt/amp) toroidal power supply for
maximum performance and reliability. A
convenient AC power entry connector
and cord make installation simple and
quick.
