Mitsubishi FR - S500 instruction manual Multi-speed operation to to, Remarks Range

2.3.4 Multi-speed operation to to

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".

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 setting dial to change the setting.

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

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

Assign the terminals used for signals RH, RM, RL and REX using Pr. 60 to Pr. 63.(*)
