14, 15 Increase/Decrease Master Frequency:
Parameter values 14, 15 program the Multi-Function Input Terminals: M1 (Pr.38), M2
(Pr.39), M3 (Pr.40), M4 (Pr.41) or M5 (Pr.42) to incrementally increase/ decrease the
Master Frequency each time an input is received.

Note: Pr.17 to Pr.23, Pr.78, Pr. 79, Pr.81 to Pr.87 define the PLC program. Another related
function is “30 One-Shot PLC Run”. It can be set to use a not-latched contact as the
run signal.
18 Counter Trigger:
Parameter value 18 programs Multi-Function Input Terminal: M1 (Pr.38), M2 (Pr.39), M3
(Pr.40), M4 (Pr.41) or M5 (Pr.42) to increase the AC drive’s internal counter. When an input
is received, the counter is increased by 1.
