Frequency setting with input signals
5.9
Frequency setting with input signals
Purpose
To control the frequency with
combinations of input signals
To command smooth speed
transition with input signals
5.9.1
Operation by multi-speed operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
Use the virtual terminals of CC-Link communication to switch among the pre-set operation speeds set in parameters.
Any speed can be selected by simply turning ON/OFF the RH, RM, RL and REX signals.

The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.
∗ This parameter can be set when Pr. 160 User group read selection = "0". (Refer to page 197)

REMARKS
For multi-speed setting, if two or three speeds are simultaneously selected, priority is given to the set frequency of the lower
signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
The RH, RM, RL signals are assigned to the virtual terminals of CC-Link communication in the initial setting. By setting "0 (RL)",
"1 (RM)", "2 (RH)" in Pr. 183 or Pr. 184 (input terminal function selection), you can assign the signals to other virtual terminals.

Description
Frequency when RH turns ON
Frequency when RM turns ON
Frequency when RL turns ON
Frequency from 4 speed to 15 speed can
be set according to the combination of
the RH, RM, RL and REX signals.
