The 2019 Engineers' Choice Grand Award-winning Siemens SINAMICS G120 Smart Access Module is a must-have accessory for interfacing with SINAMICS G120 variable frequency drives. Using any mobile device, users can 
securely connect to the G120 WiFi server then have the ability to commission a G120 drive, edit parameters, run in HAND mode, and more. The web server functionality eliminates the need to download additional software.
Highlights of SINAMICS G120 Smart Access
The Smart Access Module can be attached to any SINAMICS CU230P-2 control unit, CU240E-2 control unit, G120C drive system, or G120X drive system. It connects where the BOP and AOP drive operator panels typically reside.
Connect In Seconds
In seconds, the device generates a WiFi signal for users to connect to. Once the password is entered, the user can access the Smart Access Module interface through their device’s internet browser at “192.168.1.1”.
Once the browser loads, users are presented with a plethora of relevant drive information.
Smart Access Module Homepage
The main section of the Smart Access Module homepage is a six-tile layout that allows users to:
The bottom section gives users access to Siemens technical support and drive part numbers and firmware version information.
In-App Capabilities Explained
To fully understand the capabilities of this device, we need to dive into the main section of the homepage further.
Commissioning
The commissioning tile will first ask users to either retain the drive settings or restore to factory defaults. Then users are asked to complete basic drive parameters, such as line supply voltage, motor characteristics, I/O macros, minimum and maximum speeds, and ramp times.
Parameters
The parameter tile provides access to the complete list of drive parameters and setpoints. All parameters and their values are readable from the homepage. In addition, editable parameters can be configured on the spot, all done wirelessly through a mobile device, tablet, or laptop.
Jog & Hand Mode
The jog and hand mode tile is perhaps the most impressive. Users can take accept control of motor and then choose either JOG or HAND mode using the toggle switch on the screen. In JOG mode, users can move the motor forward or reverse at the drive’s programmed jog speed. In HAND mode, users can set a speed setpoint using a horizontal slider and send ON and OFF commands to the drive. Users can even change the speed setpoint using the slider while the motor is already running in HAND mode.
Monitoring
The monitoring tile displays key motor characteristics live. This includes parameters such as motor current, actual torque, actual speed, and motor temperature.
Diagnostics
The diagnostics tile includes three subpages. The first section presents the drive’s faults and alarms for monitoring, troubleshooting, and acknowledgement. The second is the I/O status of the drive. The final section is the drive status bits.
Backup and Restore
The backup and restore tile gives users the ability to backup drive parameters to the G120 Smart Access, restore drive parameters to the connected drive, download drive data as an XML file, and save parameters to the drive’s SD card and/or flash memory.
In summary, it is clear that there are many features of the Siemens SINAMICS G120 Smart Access Module which can be used across the board for engineers, technicians, and even maintenance personnel. It is very easy to use and is a powerful tool for any G120 drive application.
