AKD Parameter FB1.ENCRES Setting for Resolver

The setting for FB1.ENCRES (Rotary Encoder Resolution) for a resolver is set automatically in Workbench to a value of 32768 * FB1.POLES.  So it is set to 65536 for a 2-pole resolver or 131072 for a 4-pole resolver.  A resolver does not have encoder pulses or an encoder line count or resolution.  But the drive sets this parameter in order to handle the required interpolation and resolution of the resolver signals.  Basically, you can ignore this parameter when using a resolver.  But keep in mind that if you change it from the calculated value, the motor will not commutate correctly.
