(5) Waiting time setting at MC switchover
(Pr. 580, Pr. 581)
· Set a switching time of MC (e.g. time until RIO1 turns ON after RO1 turns OFF) in
Pr. 580 MC switching interlock
time
in the direct system (
Pr. 579
= "2"). You can set the time from MC switch-over to a start (time from when
RIO1 turns OFF and RIO2 turns ON until inverter output starts). Set this time a little longer than the MC
switching time.
· You can set the time from MC switch-over to a start (time from when RIO1 turns OFF and RIO2 turns ON until
inverter output starts) in
Pr. 581 Start waiting time
in the direct system (
Pr. 579
= "2"). Set this time a little longer
than the MC switching time.
(6) Acceleration/deceleration time when an auxiliary motor is connected and disconnected
(Pr. 582, Pr.583)
· You can set the deceleration time in
Pr. 582 Auxiliary motor connection-time deceleration time
for decreasing the
output frequency of the inverter if an auxiliary motor connection occurs. Set the deceleration time in
Pr. 582
from
Pr. 20 Acceleration/deceleration reference frequency
to stop.
The output frequency is not forcibly changed when "9999" is set.
· You can set the acceleration time in
Pr. 583 Auxiliary motor disconnection-time acceleration time
for accelerating the
output frequency of the inverter if an auxiliary motor disconnection occurs. Set the deceleration time in
Pr. 583
from
Pr. 20 Acceleration/deceleration reference frequency
to stop.
The output frequency is not forcibly changed when "9999" is set.
(7) Start of auxiliary motor
(Pr. 584 to Pr. 586, Pr. 590)
· You can set the output frequency of the inverter-operated motor in
Pr. 584 to Pr. 586
at which the commercial-
power supply operation motors start. When the output frequency equal to or higher than the setting continues
for longer than the time set in
Pr. 590 Auxiliary motor start detection time
, the commercial-power supply motors
start. In this case, the starting sequence depends on the pattern in
Pr. 579 Motor connection function selection
.
·
Pr. 584 Auxiliary motor 1 starting frequency
value means the frequency at which the first commercial-power supply
motor starts when the number of commercial-power supply motors. When starting the second commercial-
power supply motor when one commercial-power supply motor is running, set
Pr. 585 Auxiliary motor 2 starting
frequency
.
(8) Start of auxiliary motor
(Pr. 587 to Pr. 589, Pr. 591)
· You can set the output frequency of the inverter-operated motor in
Pr. 587 to Pr. 589
at which the commercial-
power supply operation motors stop. When the output frequency equal to or lower than the setting continues for
longer than the time set in
Pr. 591 Auxiliary motor stop detection time
, the commercial-power supply motors stop.
In this case, the stopping sequence depends on the pattern in
Pr. 579 Motor connection function selection
.
· Use
Pr. 587 Auxiliary motor 1 stopping frequency
to set the frequency at which one commercial-power supply
motor running stops. When stopping one commercial-power supply motor when two commercial-power supply
motors are running, set
Pr. 588 Auxiliary motor 2 stopping frequency
.
REMARKS
Pr. 582
and
Pr. 583
are not affected by the
Pr. 21 Acceleration/deceleration time increments
setting. (Setting range and setting
increments do not change.)
