ADL300A: the drive supports different types of encoder cards. The mode can only be selected if an incremental digital
encoder card is used. If an EN/SSI encoder card is used, the mode is automatically set by the drive in accordance with the
type of encoder detected. For all other encoder cards, the mode is set in accordance with the card used. The modes are
listed in the following table:
0 None
1 Digital FP
2 Digital F
3 Sinus
4 Sinus SINCOS
5 Sinus ENDAT
6 Sinus SSI
7 Sinus HIPER
8 ENDAT
(*) The card automatically selects the correct mode in relation to the encoder type.
Menu PAR Description
15.20 2134 Encoder speed filter
Setting of the time constant of the filter 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. On the other hand, the use of a
speed measurement filter introduces delays that do not permit high control loop dynamics. Low settings extend the regula-
tion bandwidth but may accentuate any disturbance. The filter is applied to the speed reported in the Encoder speed
parameter.
Menu PAR Description
15.21 2150 Encoder speed
The motor speed measured by the incremental encoder is displayed, filtered by the Encoder speed filter parameter.
Menu PAR Description
15.22 2162 Encoder position
The impulse count obtained from the incremental encoder reading is displayed: 1 encoder turn is equal to the value en-
tered in Encoder pulses multiplied by 4.
Menu PAR Description
15.23 2172 SpdFbkLoss code
The Speed fbk loss alarm generated by an encoder fault is displayed. Each type of encoder generates the alarm differ-
ently (incremental signal error, absolute signal error, serial error), so this parameter is used to display information about the
alarm that has been activated. In case of several concurrent causes, these are shown in this parameter.
For further details reference should be made to the description of the Speed fbk loss alarm and to the SFL alarms chapter
according to the type of feedback.
Note !
For the correct interpretation of the cause of the alarm trigger, it is necessary to transform the hex code indicated in parameter 15.14 SpdFb-
kLoss code, PAR 2172 , in the corresponding binary and verify in the encoder table that the active bits and related description are used.
