Based on the information should not be inferred a certain features or suitability for a particular application. This information does not release the user from the obligation of own judgment and verification. P.P.H. WObit E.K.J. Ober S.C. reserves the right to make changes without prior notice.
Except start/ stop inputs SIC 184 device has also 2 universal inputs, 2 outputs and dedicated inputs based motor position. It allows completely eliminate PLC driver in some applications. 2.1.1 SIC184 driver as simple and cost-effective solution at controlling of stepper motor ...
2.1.2 SIC184 driver – independent and synchronous operation of up to 16 motors simultaneously. SIC184 controllers can cooperate depending on each other in multi-master and master-slave modes, depends on programming way. On account to that there is a possibility of interdependent operation up to 16 modules simultaneously, which enables complex interdependent motion trajectories.
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.
ML-PROG software – creating of motion programs and possibility of simultaneous programming up to 16 drivers by RS485 interface. SIC184 drives operate at common RS485 bus can be programmed simultaneously by ML- PROG program and USB_RS485 converter. It enables easy creating interdependent motor motion programs multi-master or master-slave type.

Motor should be connect to the driver by 4-pin cable. To reduce noise it is recommended to use twisted cable (A with /A, B with /B), preferably shielded. In case of unipolar motors (with 6 or 8 derivation cables) you should connect them according to examples below. www.wobit.com.pl Manual -SIC184 – 27.10.2014 – v.1.1 page 11...
Never disconnect motor from driver while its operation. It can cause damage of the driver. 2.6 RS485 connector SIC184 driver is equipped in RS485 interface. It can be used for: Programming of the driver using RS485-USB converter and ML-PRG software, ...
SIC184 programs must be the same. 2.6.1. Driver communication in Modbus-RTU protocol SIC184 driver can operate as slave device in Modbus-RTU communication. While operating as slave device, which can be controlled by motion commands by record of proper registers.
Picture2. Example of motor controlling through Modbus RTU protocol. 2.6.2 Communication between SIC184 controllers in internal protocol SIC184 driver can communicate by its internal protocol through RS485. This protocol allows programming of one and/or many drivers on common RS485 bus by ML-PROG software as well as communication between drivers, while earlier recorded motion program.
USB connector is used for communication between driver and SIC-KONFIGURATOR software. After connecting driver to PC you don’t have to install drivers.

2.8 Transistor outputs SIC184 has two transistor outputs with load up to 1 A. Scheme of outputs is shown on picture below. On clamp no. 6(+) is available voltage supply of the driver, which can be used for activation of external circuits.
2.10. Encoder SIC184 controller has quadrature input for connection of position sensor, which could be : Incremental encoder couple directly with stepper motor shaft, Incremental encoder mounted indirectly e.g. with gearbox of stepper motor, Magnetic linear sensor mounted on executed element powered by stepper motor.
Encoder should be connected from controller side to GND. For configuring encoder and for control of correct the connection is designed tab Encoder In SIC184- KONFIGURATOR software (chapter: encoder settings). 3.

115200 bps) – allows to define baudrate of RS485. - Device address MODBUS (1..16) – allows to define SIC184 address on Modbus-RTU bus. - Preview of Modbus-RTU transmission – allows to preview Modbus frames comes to driver. Incorrect frames are not interpreted.
SIC184 controller can be programmed to execute proper motion program. Motion program is made in external application ML-PROG (description of creating motion commands is enclosed in separate documentation for ML-PROG program). ML-PROG program creates scripts (files with *.mlp extension) in build catalogue. This file can be send to the driver by SIC184-KONFIGURATOR program.
