The speed measurement procedure depends on the type of encoder card; minimum and maximum default
values are set according to the type of feedback card that is applied.

In the presence of the Enc 1 encoder option:
• setting 1 (Digital FP) selects the method for measuring frequency and period. This type of measurement
lets you achieve high precision and dynamics at medium and high speed.
• setting 2 (Digital F) selects the method for measuring frequency. This selection is preferable for applica-
tions that rotate at very low speeds.
In the presence of the Enc 4 encoder option:
• selection 10 (ENDAT), as opposed to selection 5 (Sinusoidal ENDAT), indicates that the encoder has no
incremental channels. Switching between the two selections is automatic by means of a recognition proce-
dure.
• selection 11 (SSI), as opposed to selection 6 (Sinusoidal SSI), indicates that the encoder has no incremen-
tal channels. Switching between the two selections has to be performed manually during commissioning.

17.2.12 2134 Encoder1speed filter ms FLOAT 2.000 0.125 20.000 ERW FVS
Setting of the time constant of the lter applied to the feedback encoder pulse reading. The parameter affects
both the accuracy of the speed measurement and the dynamics obtainable in closed loop control. Long updat-
ing times allow greater stability (more ltering) of the speed measurement, as a higher number of encoder
pulses are counted at a given speed of rotation. On the other hand, the use of a speed measurement lter
introduces delays that do not permit high control loop dynamics. Low settings extend the regulation bandwidth
but may accentuate any disturbance.

Indicates the state of Encoder 1 (1= error, 0 = no error) regardless of whether this Encoder is used/not used as
feedback for motor control.
