The 3540M/MO step motor drivers are
microstepping drives with up to 12,800
steps per revolution,
with MOSFET three state switching
amplifiers and optoisolated circuits. Both
drives include 5 optically isolated inputs, and
the 3540MO features external speed control,
tach output, and internal pots for accel/decel
rate along with high/low speed range
The 3540M drive is a step and direction drive,
and includes an automatic feature
(switch selectable) to lower motor current by 50%
anytime the motor is left at rest for more
than one second. Additionally there is a
switch-selectable self-test which rotates the
motor 1/2 revolution in each direction at
100 steps/second. This drive is compatible with PLCs which feature
high-speed pulse output, such as our ELC-PLC series and OCS XL series.
Note: the Step, Direction, and Enable inputs are +5V-logic compatible.
For operation with +24V signals, a 3600-ohm series resistor is required on each input.
See the drive manual for details.
The 3540MO drive has an on-board oscillator
which allows the motor speed to be controlled
by an analog voltage or external joystick.
This drive is ideal for continuous motion applications
such as mixers and blenders. A tach output is also available on this drive.
Motor current for both drives is selected from 32 levels by a
DIP switch. Microstepping resolution is
selectable by DIP switch on the 3540M. On the 3540MO, microstepping resolution is
fixed at 12,800 steps/revolution.
