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 FR-A720-0.4K Instruction Manual

4.11 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

4.11.1 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).

(1) Multi-speed setting (Pr. 4 to Pr. 6)
⋅ Operation is performed at the frequency set in Pr. 4 when the RH
Speed 6
signal turns on, Pr. 5 when the RM signal turns on, and Pr. 6 when the
RL signal turns on.
Speed 7
REMARKS
⋅ In the initial setting, if two or three speeds are simultaneously
Time
selected, priority is given to the set frequency of the lower signal. For
ON ON ON
example, when the RH and RM signals turn on, the RM signal (Pr. 5)
ON ON
has a higher priority.

⋅ The RH, RM, RL signals are assigned to the terminal RH, RM, RL in
the initial setting.
By setting "0 (RL)", "1 (RM)", "2 (RH)" in any of Pr.178 to Pr.189 (input
terminal function assignment), the signals can be assigned to other
terminals.

Time
Pr. 232 to Pr. 239)
⋅ Frequency from speed 4 to speed 15 can be set according to the
ON
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. 189 (input terminal function selection) to assign the function.
* When
frequency set in Pr. 6 when RH, RM and RL are turned off and REX is turned on.
