9. 14, 15: Increase/Decrease Output Frequency Control – Parameter value 14
programs a Multi-function Input Terminal: M1 (Pr.38), M2 (Pr.39), M3 (Pr.40), M4
(Pr.41) or M5 (Pr.42) to incrementally increase the AC drive output frequency by one
unit each time the corresponding input is activated. Parameter value 15 programs an
input to decrease the output frequency.
Application Note:
If the Multi-function Input Terminals programmed for Increase/Decrease Output
Frequency Control (14, 15) are asserted continuously, the output frequency will
increase or decrease unit by unit continuously. If the input is pulsed, the output
frequency will change one unit. This control function is enabled when the drive is
running. The modified frequency is stored in non-volitile memory.
10. 16, 17: PLC Function Contr ol – Parameter value 16 programs a Multi-function
Input Terminal: M1 (Pr.38), M2 (Pr.39), M3 (Pr.40), M4 (Pr. 41), M5 (Pr.42) to enable the
AC drive internal PLC function. Parameter value 17 programs and input terminal to
pause the PLC program.
Application Note:
Parameter value 16 programs a Multi-function Input Terminal: M1 - M5 to start the
internal PLC program control of the AC drive. Parameters 17 - 23, 78, 79 and 81 to 87
define the PLC program. Parameter value 17 programs an input to pause the PLC
program when the input is shorted to ground. When the input terminal is not closed,
the PLC program runs continuously.
