Frequency setting by external terminals

4.6

Frequency setting by external terminals

Purpose
Make frequency setting by
combination of terminals
Perform jog operation
Infinitely variable speed setting by
terminals
4.6.1

Operation by multi-speed 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 signals.
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 Extended function display selection = "0". (Refer to page 157)

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 terminal RH, RM, RL in the initial setting. By setting "0 (RL)", "1 (RM)", "2 (RH)" in
any of Pr. 178 to Pr. 182 (input terminal function selection), you can assign the signals to other terminals.

The inverter operates at frequencies set in Pr. 4 when RH signal is on,
Pr. 5 when RM signal is on and Pr. 6 when RL signal is on.

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.
