Preparing for Operation
Be sure to connect an NFB (no-fuse breaker) to the Inverter.
Provide sequence circuitry to the Inverter and the machines of the system con-
nected to the Inverter so that the machines will stop operating when the Inverter
has an operational error.
•The fault retry function enables the Inverter to start operating automatically after the
Inverter stops operating due to external errors. This function can be used only if the
user does not want to interrupt the mechanical system, even if it means that this func-
tion may damage the Inverter.
•Set the number of retries.
•The fault retry function detects overcurrent and overvoltage errors only. If the Inverter
has any other error, the fault retry function will not work. Instead, the protective mecha-
nism will work instantly.
•The number of fault retries are cleared in the following cases.
1. If the Inverter operates normally for 10 minutes after the fault retry function is trig-
gered.
2. If the Inverter is reset after the Inverter has any error, the protective mechanism is
actuated, and the cause of the error is removed.
3. If the Inverter is turned off and on.
n61
Stop Key Selection
Setting range
•When inputting Inverter operation from the control terminals, the Stop Key on the Digi-
tal Operator can be set to "enabled" or "disabled."
Value
0 Stop Key enabled
1 Stop key disabled
Note When operating the Inverter from the Digital Operator, the Stop Key is always en-
abled irrespective of its setting.
n62
Slip Compensation Primary Delay Time
Setting range
•This constant is used to adjust the operation of slip compensation function.
•When the slip compensation function is used, the Inverter may oscillate with the load.
In such a case, use constant n62.
•If vibration occurs, increase the setting of n62.
•When the constant is set to "0.0," the Inverter will perform the same operation as when
the constant is set to the factory setting of "2.0."
