CAUTION
⋅
The CS signal can be assigned to the input terminal using any of Pr. 178 to Pr. 189 (input terminal function selection). When
terminal assignment is changed, the other functions may be affected. Please make setting after confirming the function of
each terminal.
⋅
When automatic restart operation is selected, undervotage protection (E.UVT) and instantaneous power failure protection
(E.IPF) among the alarm outut signals will not be provided at occurrence of an instantaneous power failure.
⋅
The SU and FU signals are not output during a restart. They are output after the restart cushion time has elapsed.
⋅
Automatic restart operation will also be performed after a reset made by an inverter reset is canceled or when a retry is
made by the retry function.
Provide mechanical interlocks for MC1 and MC2. The inverter will be damaged if the power supply is input to
the inverter output section.
When automatic restart after instantaneous power failure has been selected, the motor and machine will start
suddenly (after the reset time has elapsed) after occurrence of an instantaneous power failure. Stay away
from the motor and machine. When you have selected automatic restart after instantaneous power failure
function, apply in easily visible places the CAUTION stickers supplied to the instruction manual (basic).

(4) Automatic restart operation adjustment (Pr. 163
to Pr. 165, Pr. 611)
⋅ Using Pr. 163 and Pr. 164, you can adjust the voltage rise
time at a restart as shown on the left.
⋅ Using Pr. 165, you can set the stall prevention operation level
at a restart.
⋅ Using Pr. 611, you can set the acceleration time until the set
frequency is reached after automatic restart operation is
performed besides the normal acceleration time.
Time
REMARKS
⋅ If the setting of Pr. 21 Acceleration/deceleration time increments is
changed, the setting increments of Pr. 611 does not change.
(5) Connection (CS signal)
MC2
⋅ When the automatic restart after instantaneous power failure
selection signal (CS) is turned on, automatic restart
MC3 operation is enabled.
⋅ When Pr. 57 is set to other than "9999" (automatic restart
IM
operation enabled), the inverter will not operate if used with
the CS signal remained off.
