A108 Drive controlled interpolation, lagless, encoder 1
The drive receives a position command value from the control system
which is identical to the target position of the travel path. Then the drive
generates (interpolates) an internal position command value sequence,
which uses the control system to maintain maximum values for jerk,
velocity and acceleration sequences.
The drive moves without following error (lagless) to the target position.
Encoder 1 indicates that the position encoder is installed on the motor
shaft (indirect measurement of the axis position).

Interpolation".
A109 Drive controlled interpolation, lagless, encoder 2
The drive receives a position command value from the control system
which is identical to the target position of the travel path. Then the drive
generates (interpolates) an internal position command value sequence,
which uses the control system to maintain maximum values for jerk,
velocity and acceleration sequences.
The drive moves without following error (lagless) to the target position.
Encoder 2 indicates that the position encoder is installed on the machine
axis (direct axis position measurement).

A146 Relative drive controlled interpolation, encoder 1
In the S-0-0282, Travel distance parameter, the drive receives a
distance specification from the controller. When bit 0 of the S-0-0346,
Setup flag for relative command values parameter is toggled, this
distance is summed up to the value in S-0-0258, Target position. In
order to get from the current position to the new target position, the drive
now generates (interpolates) an internal position command value curve.
This is done taking the limit values of velocity, acceleration, and jerk in the
parameters
•
S-0-0259, Positioning velocity
•
S-0-0260, Positioning acceleration
•
S-0-0193, Positioning jerk
into account.
The drive approaches the target position with a position lag that is
proportional to the velocity.
Encoder 1 means that the position encoder is attached to the motor shaft
(indirect measurement of the axis position).

interpolation".
