Example 2: set the ACC time of 01H VFD as 10s and the DEC time as 20s
P00.11
ACC time 1
Setting range of P00.11 and P00.12:
0.0 – 3600.0s
Depend on model
○
P00.12
DEC time 1
Depend on model
○
The corresponding address of P00.11 is 000B, the ACC time of 10s corresponds to 0064H,
and the DEC time of 20s corresponds to 00C8H.
