EL70x1 143Version: 4.4
Fig.164: Reference velocity parameter
Dead time compensation
The dead time compensation can be adjusted on the Time Compensation tab of Axis1_ENC.
It should theoretically be 3 cycles of the NC cycle time, although in practice 4 cycles are preferable.
Therefore, the settings of the parameters Time Compensation Mode Encoder should be ‚ON (with velocity) )‘
and Encoder Delay in Cycles ‘4’.
