7-7-4 Other precautions related to feedforward function
• If multiple feedforward functions are set in 32-byte mode, Err93.5 (Parameter setting error protection 4) will occur.
This error will not occur in 16-byte mode.
• When invalidating feedforward through the parameter, set the command area to 0.
Otherwise, command error (0034h) will occur.
• During servo-lock after completion of homing, feedforward remains valid. When this state causes problem, keep
feedforward value at 0 during cyclic homing sequence.
• During deceleration and stop process with servo-off, counter clear or drive inhibit input (POT/NOT), feedforward is
at 0.
• When feedforward value in drive inhibit direction is set after deceleration and stop process triggered by drive inhibit
input (POT/NOT), command error (0046h) will occur and feedforward value is set to 0.
• When setting value is outside the range, command error (0034h) will occur and previous normal value is held.
• When the value set during switching of control mode is outside the range, command error (0034h) will also occur
and the previous normal value will be maintained. If the feedforward in the control mode before switching is invalid,
the value is 0.
• In control mode with invalid feedforward, the feedforward value is 0.
