Parameterizing an encoder (setting - encoder parameterization)
Meaning
Sets the axis type (linear axis or rotary axis/spindle).
Sets the modulo value in degrees for rotary axes for the "Safe position"
function.
This modulo value is taken into account for safe referencing and for the
transfer of the safe position via PROFIsafe when absolute position is en‐
abled. The value should be set so that it lies precisely at 2^n revolutions,
so that when the range that can be represented overflows (+/-2048), then
the position actual value does not exhibit a step (jump).
The modulo function is deactivated for a value = 0.
Selects a configured encoder as the encoder that is used by the second
channel (control, Motor Module) for safe motion monitoring.
Encoder-monitoring channel (settings - encoder parameterization)
Meaning
Sets the motor encoder as either rotary or linear encoder.
change).
Displays the number of encoder pulses per revolution for rotary encoders.
Displays the fine resolution for G1_XIST1 in bits.
Sets the ratio between the encoder and load in mm/revolutions for a linear
axis with rotary encoder.
Actual value synchronization (settings - encoder parameterization)
Meaning
Enables/inhibits actual value synchronization.
It is not permissible to enable actual value synchronization and SLP/SP for
the same drive.
Sets the tolerance for the crosswise comparison of the actual position
between the two monitoring channels.
Displays the maximum additional difference between the load-side actual
position value on the Control Unit and the load-side actual position value
on the second channel, which can occur due to the delay of the actual
value acquisition in the EnDat 2.2 converter.
Displays the maximum difference between the load-side position actual
value on the Control Unit and the load-side position actual value on the
second channel.
