8 PARAMETER FUNCTIONS
8-4
8.3.2 Variable-speed operation using contact input signals
Pr. 4 "three-speed setting (high speed)"
Pr. 5 "three-speed setting (middle speed)"
Pr. 6 "three-speed setting (low speed)"
Pr. 24 to 27 "multi-speed setting (speed 4 to 7)"
Pr. Setting Range Unit
4 to 6 0 to 7200
0 to 7200
r/min
24 to 27
9999
Combining "ON"/"OFF" of the contact signals allows you to choose the preset
running speed (any of up to seven different speeds).
The following table lists the relationships between the contact signal input
combinations and running speeds.

Remarks
Speed 1 ON OFF OFF Pr. 4
Speed 2 OFF ON OFF Pr. 5
Speed 3 OFF OFF ON Pr. 6
When two or more contact signals are
"ON", priority is given to the signals in
order of terminals RL, RM and RL.
Speed 4 OFF ON ON Pr. 24
Speed 5 ON OFF ON Pr. 25
Speed 6 ON ON OFF Pr. 26
Speed 7 ON ON ON Pr. 27
When performing multi-speed operation at
speeds 4 and higher, set the running
speeds in the corresponding parameters.
When "9999" is set in the parameter, input
of the corresponding signal performs
operation at the lower preset speed.
MEMO
Simultaneous input of the multi-speed operation signal and analog
speed signal (across terminals 2-5) gives priority to the multi-speed
operation signal.
Any setting less than 300r/min will be a stop (0r/min) setting.
