4.8

Speed setting by external terminals

Purpose
To make speed setting by
combination of terminals
To perform Jog operation
To command smooth speed
transition with terminals
4.8.1

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.

This parameter can be set when Pr.160 Extended function display selection = "0". (Refer to page 182)

When a value exceeding 3000 r/min is set, the rotation speed will be limited at 3000 r/min.
Also, when an S-PM geared motor is used, the maximum setting value differs depending on the drive unit capacity. (0.2 to 2.2K: 12000 r/min, 3.7K: 8000 r/
min)

REMARKS
 In the initial setting, if two or three of multi-speed settings are simultaneously selected, priority is given to the set speed 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.184 (input terminal function selection), you can assign the signals to other terminals.

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