Encoder interface modules are used for Flux Vector Control operation with sensor (FVC mode) for asynchronous motors, or for Vector Control operation with speed feedback (FSY mode) for synchronous motors. They improve drive performance irrespective of the motor load state: b Zero speed torque b Accurate speed regulation b Torque accuracy b Shorter response times on a torque surge b Improved dynamic performance in transient state For asynchronous motors, in the other control modes (voltage vector control, voltage/frequency ratio), encoder interface modules improve static speed accuracy. Depending on the model, encoder interface modules can also be used for monitoring, irrespective of the control type: b Overspeed detection b Load slipping detection They can also transmit a reference value provided by the encoder input to the Altivar variable speed drive. This specific feature is used to synchronize the speed of several drives. The encoder options have a thermal sensor input to monitor one standard temperature sensor. 4 modules are available depending on the encoder technology: b Encoder with digital output b Encoder with analog output b Resolver interface b HTL encoder interface The Altivar variable speed drive can only be equipped with one of the encoder interface modules. The interface encoder module is inserted in a dedicated slot. It is protected against encoder supply short circuits and overloads.
