5.2.2 Setting the speed by switches (three-speed setting) (Pr. 4 to Pr. 6)
POINT
y Switch ON the STF (STR) signal to give a start command.
y Switch ON the RH, RM, or RL signal to give a speed command.
Operation example Operation at high speed (3000r/min)
Operation
1.
Screen at power-ON
The monitor display appears.
2.
Speed setting
Turn ON the high-speed switch (RH).
3.
Start Æ Acceleration Æ constant speed
Turn ON the start switch (STF or STR). The speed value on the indication increases in Pr. 7 Acceleration time, and " "
(3000r/min) appears.
[RUN] indicator is lit during forward rotation operation and flickers during reverse rotation operation.
z When RM is turned ON, 1500r/min is displayed. When RL is turned ON, 300r/min is displayed.
4.
Deceleration Æ Stop
Turn OFF the start switch (STF or STR). The speed value on the indication decreases in Pr. 8 Deceleration time, and the motor
stops rotating with " " (0r/min) displayed. [RUN] turns OFF.
5.
Speed setting(OFF)
Turn OFF the high-speed switch (RH)
REMARKS
y Initial values of terminals RH, RM, RL are 3000r/min, 1500r/min, and 300r/min. (To change, set Pr. 4, Pr. 5 and Pr. 6.)
y In the initial setting, when two or three of multi-speed settings are simultaneously selected, priority is given to the set speed of
the lower signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
y Maximum of 15-speed operation can be performed. ( Refer to Chapter 4 of the Instruction Manual (Applied).)
