Operation By Multi-Speed Setting - Mitsubishi Electric FR-F820-04750 Instruction Manual

Parameters
5.6.7

Operation by multi-speed setting

Use these parameters to change among pre-set operation speeds with the terminals. The speeds are
pre-set with parameters.
Any speed can be selected by simply turning ON/OFF the contact signals (RH, RM, RL, and REX signals).

Multi-speed setting (Pr. 4 to Pr. 6)
The inverter operates at frequencies set in Pr. 4 when RH signal is ON, Pr. 5 when RM signal is ON and
Pr. 6 when RL signal is ON.

Description
Without compensation
With compensation
Sets the frequency when RH is ON.
Sets the frequency when RM is ON.
Sets the frequency when RL is ON.
Frequency from 4th speed to 15th
speed can be set according to the
combination of the RH, RM, RL and
REX signals.
