Triangular wave function

If 10-23( P.234 ) set to 1, triangular wave function will be on when terminal function TRI is triggered. Please set one of
03-00
( P.83)
~03-06(
P.126
) and 03-09
(P.550)
as “36”, and then give TRI signals to the digital input terminal.

If 10-23(
P.234
) set to 2, triangular wave function will be on at any time.

Note: 1. Output frequency is limited by the upper and lower frequency limits in triangular wave operation.
2. If the values of amplitude compensation 10-25(P.236) and 10-26(P.237) are too large, over-voltage trip and
stall prevention protection will trigger.
3. This function is only valid in V/F mode (00-21(P.300)=0).
