@ Name
@ Description
_8124_set_encoder_input_mode:
There are 5 types of pulse input mode(EA/EB) including OUT/
DIR, CW/CCW, 1x , 2x, and 4x AB phase. Choose a correct
encoder input mode before using counter.
_8124_set_encoder_value:
This function is used to set the encoder( counter ) value
directly.
_8124_get_encoder_value:
This function is used to read the current encoder value.
_8124_set_encoder_up_down_count:
This function is used to set the specified encoder to count up or
count down.
_8124_set_ez_clear:
This function is used to enable the function of counter clear by
sensing EZ input signal. If enabled, you should choose falling
edge or rising edge to clear counter. On the contrary, if dis-
abled, the setting of “ClrLogic” will be ignored.
