Special operation
NOTE When the traverse function and S-pattern acceleration/deceleration (Pr. 29
S-pattern acceleration/deceleration is performed only in the areas where operation is per-
formed in normal acceleration and deceleration time (Pr. 7, Pr. 8). For acceleration/deceler-
ation during traverse operation, linear acceleration/deceleration is made.
When stall prevention is activated during traverse operation, traverse operation is stoped
and normal operation is performed. When stall prevention operation ends, the motor accele-
rates/decelerates to f0 in normal acceleration/deceleration time (Pr. 7, Pr. 8). After the out-
put frequency reaches f0, traverse operation is again performed.

When the value of amplitude inversion compensation amount (Pr. 594, Pr. 595) is too large,
pattern operation as set is not performed due to over voltage shut-off and stall prevention.
Changing the terminal assignment using Pr. 178 to Pr. 189 "Input terminal function selec-
tion" may affect the other functions. Please make setting after confirming the function of
each terminal.
