Multi-Speed Operation To To - Mitsubishi FR - S500 Instruction Manual

2
.3.4 Multi-speed operation
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 setting dial
