In accordance with international standards, a positive reference corresponds to clockwise motor rotation, seen from
the command side (shaft). For correct operation, the control algorithms ensure that a positive speed reference cor-
responds to a positive speed measurement.
If the motor pulley is mounted on the side opposite the command side, it will turn in an anticlockwise direction when
the speed is positive: to make the pulley turn in a clockwise direction, the motor phase sequence is modified, which
inverts the speed measurement sign. To restore the correct speed measurement sign, invert the incremental encoder
A+ and A- signal.
Menu PAR Description
17.9 2132 Encoder 1 mode
Setting of the method for measuring the speed of the encoder connected to the optional card. The drive automati-
cally recognises the encoder card that is inserted and only shows the methods that are compatible.

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.
Menu PAR Description
17.10 2134 Encoder1speed 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. Long updating times
allow greater stability (more filtering) 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 filter introduces delays that do not
permit high control loop dynamics. Low settings extend the regulation bandwidth but may accentuate any distur-
bance.
Menu PAR Description
17.11 2150 Encoder 1 speed
The motor speed measured by the encoder is displayed.
Menu PAR Description
17.12 2162 Encoder 1 position
The encoder position is displayed. The scale is Number of encoder impulses *4.
Menu PAR Description
17.13 2172 SpdFbkLoss code
The Speed fbk loss alarm generated by an encoder fault is displayed. As each type of encoder generates the alarm
differently (incremental signal error, absolute signal error, serial error), this parameter displays information about the
alarm that has occurred. If there are several, simultaneous causes, these are shown in this parameter.
