it is necessary to change the corresponding bit in F4-38 and F4-39 (these two parameters
respectively specifying the active mode setting of DI1 to DI5 and DI16 to DI10) to 1.
The AC drive also provides F4-10 (DI filter time) for the DI signal to improve the anti-
interference level. For DI1 to DI3, the AC drive provides the DI signal delay function,
convenient for some applications requiring delay.

can be allocated with a function among the 50 functions. For details, see descriptions of F4-
00 to F4-09.
The hardware design allows only DI5 to receive high-speed pulse signal. If high-speed pulse
count is required, use DI5.
