Frequency setting by external terminals

4.6 Frequency setting by external terminals
Purpose
Make frequency setting by
combination of terminals
Perform jog operation
Added compensation for multi-speed
setting and remote setting
Infinitely variable speed setting by
terminals
4.6.1
Multi-speed setting operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
Can be used to change the preset speed in the parameter with the contact terminals.
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, 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.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 173)
*
(1) Multi-speed setting (Pr. 4 to Pr. 6)
Operation is performed at the frequency set in Pr. 4 when the RH signal turns on, Pr. 5 when the RM signal turns on,
and Pr. 6 when the RL signal turns on.
REMARKS
In the initial 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 terminal RH, RM, RL in the initial setting.
By setting "0 (RL)", "1 (RM)", "2 (RH)" in any of Pr.178 to Pr.189 (input terminal function assignment), you can assign the signals to
other terminals.

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