Note 0.75 kW max.: Approximately 1 s.
1.5 kW max.: Approximately 2 s.
Digit 2 = 0: Constant setting is disabled during running
Digit 2 = 1: Constant setting is enabled during running
(no-09 to no-17, no-22, no-23, no-29, no-45 are enabled)
Digit 3 = 0: Level of stall-preventive operation during acceleration
is constant in the motor constant output power area
Digit 3 = 1: Level of stall-preventive operation during acceleration
is automatically decreased in the motor constant output power
area.
Note Motor constant output power area is a frequency area higher than
the maximum voltage frequency (base frequency). Set the 3rd digit
to “1” when using a high-speed motor.
2-8-22 Enable/Disable Setting Constants in DRIVE Mode
Item name Constant to be set Factory preset
Enable/Disable setting constants 9 to 17, 22,
23, 29, 45, and 57 in DRIVE mode
No. 46 0
Digit 2 = 0: Read only
Digit 2 = 1: Write possible
2-8-23 No. of Auto Reset/Restart Operation (No. 47)
Item name Constant to be set Factory preset
Fault retry selection No. 47 00
Sets the number of auto reset/restart tries (up to 10). Setting this
constant to zero disables the auto reset/restart operation.
Each time a OC, OV, OH , or GF fault occurs, the number of auto
reset/restart tries is incremented by one. If this number reaches
the value set in No. 47, another auto reset/restart attempt is not
made.
The number of auto reset/restart tries is cleared to zero when:
•No fault occurs for 10 minutes.
•A fault reset signal is input from external terminals or Digital
Operator.
•Power is turned off.
Note GF is for Single-phase Input Models only.
