● When the X37 signal turns OFF during traverse operation, the inverter accelerates/decelerates to
f0 according to the normal acceleration/deceleration time (Pr. 7, Pr. 8). If the start command (STF
or STR) is turned OFF during traverse operation, the inverter decelerates to a stop according to
the normal deceleration time (Pr. 8).
If the set frequency (f0) and traverse operation parameters (Pr. 598 to Pr. 597) are changed during
traverse operation, this is applied in operations after the output frequency reaches f0 before the
change was made.
If the output frequency exceeds Pr. 1 "Maximum frequency" or Pr. 2 "Minimum frequency" during
traverse operation, the output frequency is clamped at the maximum/minimum frequency when
the set pattern exceeds the maximum/minimum frequency.
When the traverse function and S-pattern acceleration/deceleration (Pr. 29 ≠ "0") are selected,
S-pattern acceleration/deceleration operation occurs only in the range operated at the normal
acceleration/deceleration time (Pr. 7, Pr. 8). Acceleration/deceleration during traverse operation is
If stall prevention activates during traverse operation, traverse operation stops and normal opera-
tion begins. When stall prevention operation is completed, the inverter accelerates/decelerates to
f0 at the normal acceleration/deceleration time (Pr. 7, Pr. 8). After the output frequency reaches f0,
the traverse operation begins again.
If the value of the amplitude inversion compensation amount (Pr. 594, Pr. 595) is too large, an
overvoltage trip or stall prevention occurs, and pattern operation cannot be performed as set.
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may
affect the other functions. Set parameters after confirming the function of each terminal.
