2.20 – Encoder offset
(M_Offset: 0.0’ - 359.9')
The encoder offset angle between the zero point of absolute encoder and the electrical
zero point of motor winding for synchronous motors.
Before a normal operation of synchronous motor it is required to measure the encoder
offset. This parameter is measured automatically by the inverter during auto tune. For further
information see section “20. Driving Synchronous Machines with ADrive”
After the auto tune process, note the value of this parameter. When the inverter need to be
changed because of a failure, this parameter must be set to this value manually for the new
inverter without performing a new auto tune process. The auto tune process must be performed
when the relative position between motor and encoder changes.
2.21 – Absolute encoder type ( SC.EnDat-2048 / SC.SSI-2048 / SC.SC-2048)
The type of absolute value encoder.
SC.EnDat-2048
: 2048 pulse/revolution EnDat encoder.
SC.SSI-2048
: 2048 pulse/revolution SSI encoder
SC.SC-2048
: 2048 pulse/revolution SinCos encoder
In this version of ADrive only 2048 pulse/revolution value can ve selected. Please ask
ARKEL for different pulse/revolution values.
