and
P.239 is 0.01s.
When
P.21=1, the unit of P.

<Setting>
• If P.234 “Triangular wave function selection” is “1” and triangular wave operation signal (TRI)
is turned on, triangular wave function will be valid. Set any parameter
in P.80~P.84, P.86, P.126, P.550 “Input terminal selection function” to “36” and then assign
the TRI signal for the external terminal.
• If P.234 “triangular wave function selection” is equal to “2,” the triangular wave function is
effective at any given time.

Output
frequency
Note: 1. During the movement of the triangular wave, the output frequency is limited by the maximum and
the minimum frequency.
2. If the amplitude compensation, i.e., P.236 and P.237, is too big, over-voltage will be tripped off and
the stall prevention action will be executed automatically. Consequently, the set method will not
be carried out.
3. This function is only valid under the V/F mode; i.e., it is effective when P.300
=0.
