266 JVL Industri Elektronik A/S - User Manual - Integrated Stepper Motors MIS23x, 34x, 43x
12.2 Step motor controllers (SMCxx)
The compact step motor controller SMC75 is
designed for positioning and speed control of
stepper motors.
SMC75 is a PCB with di-
mensions 57x57mm and mounted with
SMD electronics on both sides.
It is mounted directly in the housing of the JVL
QuickStep motors MIS 231, 232 and 234,
forming a complete integrated step motor.
It may also be used with other types of step
motors according to customers requirements.
The basic features of the controller are:
• Serial RS485 or 5V serial position control-
ler
• Position controller with graphic program-
ming.
• Option for CANbus, CANopen DS-301/
DSP-402 or DeviceNet (under develop
-
ment).
• A dual supply facility is available so that
position and parameters are maintained at
emergency stop
• Gear mode
• MACmotor protocol so MACmotor and
Quickstep motors can be connected on
the same RS485 bus
• Command for easy PLC/PC setup and
communication
• Power supply 12-48VDC
• Fixed 1600 pulses/rev.
• Built-in µprocessor with 8 In/Out that can
be configured as inputs, PNP outputs or
analogue inputs. 5V serial and RS485 inter
-
face for set up and programming.
•MODBUS interface.
• 9.6 to 1Mb communication
• Driver technology is improved as com-
pared to SMD73 and supply voltage is
12-48VDC (Control voltage 12-
28VDC).
When used with the QuickStep motor or
mounted on any other step motor the ad-
vantages of the controller are:
• De-central intelligence.
• Simple installation. No cables between
motor and driver.
• EMC safe. Switching noise remains
within motor.
• Compact. Does not take space in cabi-
net.
• Low-cost alternative to separate step
or servo motor and driver.
• Stall detect by means of magnetic
encoder with resolution of up to 1024
pulses/rev.
• Interface possibilities to the SMC75
controller:
• From PC/PLC with serial commands via
5V serial or RS485.
• Pulse/direction input. Encoder output.
• CANopen, DeviceNet
• 8 I/O, 5-28VDC that can be configured
as Inputs, Outputs or analogue inputs
• Future option for Profibus DP, Ethernet,
Bluetooth and Zigbee wireless
