Mitsubishi Electronics FR-S500 Multi-speed operation Pr , Pr , Pr Pr to Pr , Pr to Pr

Explanation of functions (parameters)

2.3.4Multi-speed operation (Pr. 4 , Pr. 5 , Pr. 6 ,

Pr. 24 to Pr. 27 , Pr. 80 to Pr. 87 )

Used to switch between the predetermined running speeds.

Any speed can be selected by merely switching on/off the corresponding contact signals (RH, RM, RL, REX signals).

By using these functions with Pr. 1 "maximum frequency" and Pr. 2 "minimum frequency", up to 17 speeds can be set.

This function is valid in the external operation mode or in the combined operation mode which is available when Pr. 79 = "3" or "4".

<Setting>

•Set the running frequencies in the corresponding parameters.

Each speed (frequency) can be set as desired between 0 and 120Hz during inverter

operation.
When the parameter of any multi-speed setting is read, turn the	to change the
setting.

In this case, press the SET ( WRITE ) to store the frequency. (This is also enabled in the external mode.)

The setting is reflected by pressing the SET ( WRITE ).

•Assign the terminals used for signals RH, RM, RL and REX using Pr. 60 to Pr. 63. (When terminal assignment is changed using Pr. 60 to Pr. 63, the other functions may be affected. Please make setting after confirming the function of each terminal.)
