Frequency Setting By External Terminals; Multi-Speed Setting Operation (Pr. 4 To Pr. 6, Pr. 24 To Pr. 27, Pr. 232 To Pr. 239) - Mitsubishi Electric F700 Instruction Manual

Frequency setting by external terminals

4.6 Frequency setting by external terminals

Purpose
Make frequency setting by
combination of terminals
Perform jog operation
Added compensation for multi-speed
setting and remote setting
Infinitely variable speed setting by
terminals
4.6.1

Multi-speed setting operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)

Can be used to change the preset speed in the parameter with the contact terminals.
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX signals).

⋅ Frequency from speed 4 to speed 15 can be set according to the
combination of the RH, RM, RL and REX signals. Set the running
frequencies in Pr. 24 to Pr. 27, Pr. 232 to Pr. 239. (In the initial value
setting, speed 4 to speed 15 are unavailable.).
⋅ For the terminal used for REX signal input, set "8" in any of Pr. 178 to
Pr. 186 to assign the function.
*1 When "9999" is set in Pr.232 Multi-speed setting (speed 8), operation is performed at
frequency set in Pr.6 when RH, RM and RL are turned off and REX is turned on.

REMARKS
selected, priority is given to the set frequency of the lower signal. For
example, when the RH and RM signals turn on, the RM signal (Pr. 5)
has a higher priority.

By setting "0 (RL)", "1 (RM)", "2 (RH)" in any of Pr.178 to Pr.189 (input
terminal function assignment), you can assign the signals to other
terminals.
