6.5.3 Operation from Rated Speed Rotation to Low Speed Rotation
This is the procedure to select low speed operation during rated speed rotation or when
accelerating at a speed above the low speed.(see Fig. 6-5)
LOCAL Operation
(1) Set the low speed value with the setting mode/rotational speed settings/low speed setting
set value on the LCD display. (See Section 6.6 "Software Operation" (4).) After this setting
has been made once, it does not have to be repeated each time.
(2) Next, select the LOW SPEED mode using the setting mode/rotational speed settings/
speed setting set value on the LCD display. (See Section 6.6 "Software Operation" (4).)
(3) While the speed is changing, "*" is displayed after the monitor mode/speed display. (See
Section 6.6 "Software Operation" (1).)
(4) The pump monitor mode/operation mode LCD switches from "NORMAL" to "BRAKE" and
the pump starts to decelerate. Then the NORMAL SPEED lamp (Fig. 2-1 (12)) goes off.
(5) When the rotational speed reaches the set low speed value, the NORMAL SPEED lamp
lights and the pump monitor mode/operation mode LCD switches from "BRAKE" to
"NORMAL."
(6) The pump stops decelerating and the pump speed is maintained.
※
A normal start-up and normal operation occurs if the mode is reverted to NORMAL speed
before the pump speed reaches the set low speed value.
REMOTE Operation
(1) Set the low speed value with the setting mode/rotational speed settings/low speed setting
set value on the LCD display. (See Section 6.6 "Software Operation" (4).) After this setting
has been made once, it does not have to be repeated each time.
(2) Input the "LOW SPEED" signal (see Table 6-3) from the remote-control connector (Fig. 2-
2 (23)).
(3) The pump starts to decelerate when the remote-control connector "NORMAL" signal (see
Table 6-3) turns OFF and the "BRAKE" signal (see Table 6-3) turns ON.
(4) When the pump speed reaches the set low speed value, the remote-control connector
"BRAKE" signal turns OFF and the "NORMAL" signal turns ON.
(5) The pump stops decelerating and the pump speed is maintained.
※
A normal start-up and normal operation occurs if the "LOW SPEED" signal is cancelled
before the pump speed reaches the set low speed value.
6.5.4 Operation from Low Speed Rotation to Rated Speed Rotation
This is the procedure to select normal speed operation during low speed rotation.
