The SINAMICS Motor Control Extended (license) software option for SINAMICS G220 enables high-performance encoderless closed-loop control of synchronous reluctance motors from standstill, by enabling pulseue at very low speeds.
Main benefits
Reduces commissioning time and effort
(less configuration, tuning and wiring)
Saves energy due to permanent operation in closed-loop vector control
Saves cost for encoder, cable, installation, spares, etc.
Allows continuous operation at near zero speeds including torque control
Improves system stability and robustness
Improves drive dynamic performance
Improves reliability and availability by reducing system complexity
Example 1: Low speeds, robustness and energy efficiency
The following diagram shows a measured load cycle. In the low speed range, the software option Motor Control Extended leads to significant reduced currents and therefore increased energy efficiency. Also, continuous operation with high loads is possible near zero speed.
When medium speeds are reached (in diagram: rectangle), the control switches from the pulseue to standard sensorless vector control.
Example 2: Dynamic behavior
In the following measurement, a sinusoidal signal was used to demonstrate the dynamic performance of the pulseue. The sinusoidal signal is reproduced perfectly with the pulseue while maintaining a relatively low current compared to the standard sensorless control near zero speed. For higher sinusoidal fre, the standard control would not be able to work.
This shows perfectly that with the software option Motor Control Extended, also high dynamic applications that need fast reaction times at low speeds without ramps are possible.
In which cases should the Motor Control Extended software option be used?
With synchronous reluctance motor drive
the application requires frequent or long or even permanent operation at very low speeds during operation cycle and/or precise torque control from 0 rpm is required (e. g. winders, mixers, extruders).
If the load peak at start is difficult to predict or changes dynamically and/or positioning in the application is required (e. g. logistics, cranes, hoists).
If the drive dynamic performance is critical, re operation with no or very short ramps in closed-loop (e. g. servo pumps).
If the motor works in harsh conditions or it is impossible to use an encoder (dust, heavy vibrations, mechanical restrictions) (e. g. heavy industry).
