Encoder 1 actual position value 1 (G1_XACT1)

●Resolution: Encoder lines ∙ 2n

n: fine resolution, no. of bits for internal multiplication The fine resolution is specified via p0418.

●Used to transmit the cyclic actual position value to the controller.

●The transmitted value is a relative, free-running actual value.

●Any overflows must be evaluated by the master controller.

●Encoder lines of incremental encoder

–For encoders with sin/cos 1Vpp:

Encoder lines = no. of sinusoidal signal periods

●After power-up: Gx_XIST1 = 0

●An overflow in Gx_XIST1 must be viewed by the master controller.

●There is no modulo interpretation of Gx_XIST1 in the drive.

Encoder 1 actual position value 2 (G1_XACT2)

Different values are entered in Gx_XACT2 depending on the function. ● Priorities for Gx_XIST2

The following priorities should be considered for values in Gx_XIST2:
