Name
- Use filter to smooth feed-forward
compensation value, which is
differentiated position command. Cutoff
frequency of this filter can be adjusted.
Position
- Only effective when feed-forward
compensation (FF) gain is not "0", and if
FF Filter Cutoff
overshoot takes place by inserting a
frequency
value other than "0", set the SEt-07 to "0".
* Also refer to Fig 6.29 Block Diagram of
Electronic Gear.
- An overflow alarm occurs if the
difference between position command
and actual motor position is greater than
Overflow Level
the setting value.
- Alarm CODE=33(Output alarm code in
CN2 37,38, 39)
- Inputs feed-forward gain about speed
value, which is differentiated position
command.
- If the value is set high, it is possible to
reduce delay term of the position
controller and positioning completion
speeds up, and position error is reduced
Position
during the operation. However, vibration
Feedforward Gain
may occur and performance of controller
may be reduced according to load type
or rigidity.
- Feed-forward function is ineffective when
setting "0"
