2.1.3. SIC184 driver – controlling from external devices by Modbus protocol

-

SIC184 controller can communicate with external devices by RS485 bus in Modbus-RTU
protocol, operating then as slave device. Possibility of independent addressing in range 1..16
provides simultaneous controlling of up to 16 stepper motors from devices such PLC drivers,
HMI panels or other master Modbus RTU devices.

2.1.4 SIC184 driver- indexer for high-current stepper motor driver

-

SIC184  driver  has  additional  output  for  external  power  driver  of  stepper  motor  in
STEP/DIVISION  standard,  which  allows  for  controlling  of  motors with  higher  current,  or  for
simultaneous controlling of several motors.
