MSE570 Bipolar Stepper
Motor Drive Board
Data Sheet
Specifications
Bipolar stepper motor drive with optional thermal
protection and on board oscillator.
Electrical
Motor supply:
+15 to +36Vdc (+10% max.) smoothed unregulated.
Logic supply:
+15 to +24Vdc (+10% max.) smoothed unregulated.
Note: the motor and logic may share the same power
supply up to +24V or up to +36V if a suitable dropper
resistor is fitted in the logic supply line.
Auxiliary outputs (available for external circuitry):
+12V regulated 50mA maximum
+5V regulated 50mA maximum
Motor drive output:
Bipolar chopped constant current with overload
protection. Suitable for driving hybrid or permanent
magnet stepper motors with 4,6 or 8 leads.
Maximum output current 3.5A per phase.
Output current set by on-board DIP switches or external
programming resistor.
Control inputs:
CMOS schmitt trigger inputs operating at +12V with
10K
Ω pull-up resistors and diode isolation.
Logic 0 (low) - 0V to +2V or contact closure to 0V.
Logic 1 (high) - +9V to +30V maximum or open circuit.
Monitor outputs:
Open collector NPN transistor, referenced to 0V.
Low level - +1V maximum at 30mA maximum.
High level - open circuit +24V dc maximum.
Mechanical and physical
Card size:
Eurocard format 160 mm long x 100 mm wide x 62 mm
high.
Weight:
700g approximately.
Connector:
32 way a & c DIN41612 type D.
Operating temperature range:
0
°C to 40°C maximum ambient.
External connections
External connections are made via a 32 way a & c
DIN41612 type D connector.
The MSE562 is a suitable power supply unit to power up
to two MSE570 drives.
