Function
Control, protection and monitoring functions
Closed-loop control
The drive can be controlled by means of vector control algorithm without an encoder (standard) or with it (option).
Auto tuning
Auto tuning is available to optimize the control performance of the drive
Automatic restart
Automatic restart is a custom feature, used to purposely restart and restore the drive operation after a power failure
or power removal. When Automatic Restart function is specified by the customer, a qualified Siemens personnel must
configure and ensure the function is executes as specified
Energy saver
Energy saver control allows the reduction of motor losses, and improves overall efficiency, when the
demanded motor load is low. Depending on the motor load, the control will reduce motor flux.
As motor load increases, the control will increase motor flux.
Flying restart
The flying restart function permits smooth connection of the drive to a rotating motor.
Diagnostics functions
• Self-diagnosis of control hardware
• Non-volatile memory for reliable diagnosis when the power supply fails
• Monitoring of IGBTs with individual messages for each cell
• User-friendly local operator panel with plain text messages
• Fault log with first-in indication and time/date stamp
User configurable
digital meters
The user can select indication of speed, voltage, current, input/output power, and efficiency on the
operator panel.
Process control system
The optional Process Tolerant Protection Strategy (ProToPS) is a groundbreaking process control system
available exclusively from Siemens. Instead of tripping the drive and automatically shutting down the
system due to a malfunction, ProToPS provides a hierarchical system of warnings. This control strategy allows
time to evaluate the situation and respond appropriately to avoid a system shutdown.
Operating hours and
switching cycle counter
The amount of the time that the drive was operational since it was commissioned can be displayed.
The switching cycle counter can be generated by means of an event log from the drive controller.
Detection of actual
motor speed
The control algorithm calculates actual motor speed from currents and voltages measured at the drive output.
Emergency stop button
The drives are equipped as standard with an Emergency Stop button (red mushroom button with yellow
collar) which is fitted in the cabinet door. The contacts of the pushbutton are connected in parallel to the
terminal block so they can be integrated in a protection concept on the plant side.
Insulation monitoring
An optional output signal can be provided to operate the customer protection.
I/O monitoring
I/O signals allow user customization of the system and they can be monitored remotely or by using the operator
panel display.
Thermal overload
protection
Based on the output signals of the drive, the thermal motor model is calculated. The motor thermal overload
protection algorithm prevents the motor from being exposed to excessive temperatures.
