GROUP
A
Adjustment of restart operation (Pr.163 to Pr.165, Pr.611)
NOTE
•
Pr.163
to
Pr.165
are invalid under Real sensorless vector control and vector control.
• Changing the
Pr.21
setting does not affect the
Pr.611
setting increment.
• Changing the terminal assignment using
Pr.178 to Pr.189 (Input terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
• When the restart operation is selected, undervoltage (E.UVT) and instantaneous power failure (E.IPF) of the fault output
signals become invalid.
• The SU and FU signals are not output during the restart. These signals are output after the restart cushion time passes.
• Restart operation is also performed after the inverter reset is released or after the retry by the retry function occurs.
• The automatic restart after instantaneous power failure function is invalid when the load torque high-speed frequency control
(
Pr.270
= "2, 3, 13") is set.
Parameters referred to
Pr.7 Acceleration time, Pr.21 Acceleration/deceleration time increments
Pr.13 Starting frequency
Pr.65, Pr.67 to Pr.69 retry function
Pr.78 Reverse rotation prevention selection
Pr.178 to Pr.189 (Input terminal function selection)
• The voltage cushion time at a restart can be adjusted by
Pr.163 and
Pr.164
as shown in the figure on the left.
• The stall prevention operation level at a restart operation can be set at
Pr.165
.
• Using
Pr.611
, the acceleration time to reach
Pr.20 Acceleration/
deceleration reference frequency
after a restart operation can be set.
This can be set individually from the normal acceleration time.
CAUTION
Provide a mechanical interlock for MC1 and MC2. The inverter will be damaged if power supply is
input to the inverter output section.
When the automatic restart after instantaneous power failure function is selected, the motor
suddenly starts (after reset time passes) when an instantaneous power failure occurs. Stay away
from the motor and machinery.
Apply the supplied CAUTION stickers to easily visible places when automatic restart after
instantaneous power failure has been selected.
