PARAMETERS
4.8 Speed setting by external terminals
4.8.1 Operation by multi-speed operation (Pr.4 to Pr.6, Pr.24 to Pr.27, Pr.232 to Pr.239)
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)

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).

(1) Multi-speed setting for 3 speeds (Pr.4 to Pr.6)
The drive unit operates at speeds set in Pr.4 when RH signal is ON,
Pr.5 when RM signal is ON and Pr.6 when RL signal is ON.
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.
