5.9.5 Frequency setting via pulse train input
A pulse train input to the terminal JOG can be used to set the inverter's speed command.
Moreover, speed synchronized operation of an inverter can be performed by using the pulse train
output together with the terminal JOG.
Function assigned to Pr. 185 "JOG terminal function selection".
Valid only for the FM type inverters.
Selection of pulse train input (Pr. 291)
●
Setting Pr. 291 "Pulse train I/O selection" = "1, 11, 21, 100" and Pr. 384 "Input pulse division scaling
factor"
≠
"0" changes the function of terminal JOG to a pulse train input so that the frequency can
be set to the inverter. In the initial setting, the JOG signal is assigned to terminal JOG. A maximum
pulse train of 100k pulses/s can be input.
