• When the output frequency reaches f0 and the X37 signal turns ON, the inverter begins traverse operation and accelerates
to f0 + f1. The acceleration time at this time is according to the Pr.596 setting. (If the X37 signal turns ON before the output
frequency reaches f0, traverse operation begins after the output frequency reaches f0.)
• After the inverter accelerates the motor to f0 + f1, this is compensated with f2 (f1 × Pr.594), and the motor decelerates to
f0 - f1. The deceleration time at this time is according to the Pr.597 setting.
• After the inverter decelerates the motor to f0 - f1, this is compensated with f3 (f1 × Pr.595), and the motor accelerates again
to f0 + f1.
• When the X37 signal turns OFF during traverse operation, the inverter accelerates/decelerates the motor 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 the motor to a stop according to the normal deceleration time (Pr.8).
NOTE
• If the set frequency (f0) and traverse operation parameters (Pr.593 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 performed linearly.
• If stall prevention activates during traverse operation, traverse operation stops and normal operation 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.
