Making the settings
Table 6-1
Parameterizing an encoder (setting - encoder parameterization)
Setting
Meaning
Axis type
Sets the axis type (linear axis or rotary axis/spindle).
SP modulo value
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.
Encoder selection 2nd
monitoring channel
Selects a configured encoder as the encoder that is used by the second
channel (control, Motor Module) for safe motion monitoring.
Table 6-2
Encoder-monitoring channel (settings - encoder parameterization)
Setting
Meaning
Encoder type
Sets the motor encoder as either rotary or linear encoder.
Invert position actual value Activates/deactivates the inversion of the position actual value (sign
change).
Encoder pulses
Displays the number of encoder pulses per revolution for rotary encoders.
Fine resolution X_IST2
Displays the fine resolution for G1_XIST1 in bits.
Leadscrew pitch
Sets the ratio between the encoder and load in mm/revolutions for a linear
axis with rotary encoder.
Table 6-3
Actual value synchronization (settings - encoder parameterization)
Setting
Meaning
Enable
Enables/inhibits actual value synchronization.
It is not permissible to enable actual value synchronization and SLP/SP for
the same drive.
Actual value tolerance
Sets the tolerance for the crosswise comparison of the actual position
between the two monitoring channels.
Additional actual value tol‐
erance
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.
Maximum actual value tol‐
erance
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.
