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

3.5 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
3.5.1

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 signals.
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX signals).

The above parameters allow its setting to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter
write selection.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 140)

(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 selected,
Time
ON ON ON
priority is given to the set frequency of the lower signal. For example,
ON ON when the RH and RM signals turn on, the RM signal (Pr. 5) has a higher
ON priority.
(2) Multi-speed setting higher than speed 4 (Pr. 24 to Pr.
27, Pr. 232 to Pr. 239)
⋅ Frequency from speed 4 to speed 15 can be set according to the
Speed 15
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
Time
setting, speed 4 to speed 15 are unavailable.).
⋅ For the terminal used for REX signal input, set "8" in any of Pr. 178
ON
to Pr. 186 to assign the function.
*1 When only the REX signal turns on with Pr. 232 Multi-speed setting (speed 8) set to
"9999", the set frequency becomes the low speed running frequency (Pr. 6) .
