Sinamics V20 Convertor Details
The SINAMICS V20 is operated from a built-in Basic Operator Panel (BOP). A single press of the stop button triggers an OFF1 ramp-down in HAND mode. A double press within 2 seconds, or a press longer than 3 seconds, triggers OFF2, which lets the motor coast to a standstill. The multi-function and OK buttons do different things on short presses (under 2 s) and long presses (over 2 s). For example, a long press opens the setup menu, returns to the status screen or opens fault information.
A key combination switches between HAND, JOG and AUTO modes. The hand icon is steady in HAND mode, flashes in JOG mode and is hidden in AUTO mode. JOG is only available while the motor is stopped. Pressing UP and DOWN together reverses the direction of rotation. In AUTO mode, this combination only works if P1113 remains connected to r0019.11. Parameters can be edited normally or digit by digit, and P8553 adds short text labels to the menus.
Instead of wiring each function by hand, you can load connection macros. Available macros include BOP-only control, terminal control, fixed speeds, push-button control with or without an analog setpoint, two PID configurations, and USS or MODBUS RTU control. In the setup wizard, a minus sign marks the macro that is currently active. You can switch from PNP to NPN logic by connecting the digital input common (DIC) to 24 V.
For quick commissioning on the panel, set P0010 = 1, choose the 50/60 Hz region with P0100, and enter the motor nameplate data in P0304 to P0311. Then set the command source, setpoint source, frequency limits and ramp times. Setting P3900 = 3 finishes the process and calculates the motor data. If you set P1900 = 2, the converter identifies all motor parameters at standstill. Alarm A541 warns that this measurement will run on the next ON command.
The optional SINAMICS V20 Smart Access is a Wi-Fi web server module. It is meant for commissioning only and cannot stay fitted permanently. From a PC, tablet or smartphone, you can use it for quick commissioning, parameter setting, JOG, monitoring, diagnostics, and backup and restore. The web wizard covers motor data, connection macros, application macros such as pump, compressor and conveyor presets, and key parameters. If optimization fails, the wizard offers to run it again.
For control functions, the drive has a full PID controller with setpoint, trim and feedback sources, a feedback filter, and proportional, integral and derivative settings. Flying start (P1200) can catch a motor that is still turning, which helps with high-inertia loads. Automatic restart (P1210) has eleven modes for handling mains brownouts, blackouts and faults. Up to 16 fixed frequencies can be selected in binary mode.
Braking can be set up as DC braking, compound braking or dynamic braking. The Vdc controller has Vdc_max regulation and kinetic buffering. It must be disabled (P1240 = 0) before dynamic braking can work. Three command data sets and three drive data sets can be switched through BICO inputs. Command data sets can be changed in both the Ready and Run states, while drive data sets can only be changed in the Ready state.
For diagnostics, the drive stores a fault history in r0947 and r0949, a fault bit array in r3113 and a warning log in r2110. A MODBUS register map gives access to current, voltage, DC bus voltage, torque, power, total kWh and fault codes. Parameters can be cloned to an SD card formatted as FAT16 or FAT32. A QR code with an IEC 61406-1 ID link gives access to product data, manuals and certificates.
