If
P.21
=0, the minimum increments of
P.238 and P.239 is 0.01 seconds.
If P.21=1, the minimum increments of
P.238 and P.239 is 0.1 seconds.
<Setting>
•
The triangular wave function is effective if the value of parameter P.234 is 1 and the signal is on.
Please set 36 to any parameter:
P.80~P.84, P.86
, corresponding to the external terminal assigned for
TRI signal.
•
If the value of the parameter is 2, it means the triangular wave function is effective all the time.

Note: 1. The output frequency will be limited by the maximum frequency and minimum frequency when the
triangular wave function is effective.
2. If the amplitude compensation (P.236 or P.237) is too larger, over-voltage trip and stall prevention
operation will run automatically. Thus the inverter can not run according to the triangular wave function.
