Fig. 23 setting jump frequencies
•
Operation is prohibited within the jump frequency range, but changes during
acceleration and deceleration are smooth with no jump. To disable this function,
set the jump frequency 1
∼
3 (Cn-20
∼
Cn-22) to 0.0Hz.
•
For the jump frequency 1
∼
3 (Cn-20
∼
Cn-22), set the center frequency to be jumped.
•
Be sure to set the jump so that Cn-20
≥
Cn-21
≥
Cn-22. If not, a message “Jump
frequency setting error” is displayed. For Cn-23, set the jump frequency
bandwidth. If Cn-23 is set as 0.0Hz, the jump frequency function is disabled.
(18) Number of Auto Restart Attempt (Cn-24)
•
The fault restart function will restart the inverter even when an internal fault
occurs during inverter operation. Use this function only when continuing operation
is more important than possibly damaging the inverter.
•
The fault restart function is effective with the following faults. With other faults,
the protective operations will engage immediately without attempting to restart
operation.
•
Over-current
•
Ground fault
•
Main circuit over-voltage
•
The fault restart count will automatically increase upon the restart activated and
will be cleared in the following cases:
a. When the operation is normal for 10 minutes after a fault restart is performed.
b. When the fault-reset input is received after the protection operation has been
activated and the fault confirmed. (e.g., by pressing
RESET
or enable Fault reset
terminal
e
)
c. When the power is turned off and on again.
•
When one of the multi-function output terminals (RA-RB-RC or R1A-R1B-R1C,
DO1, DO2 or R2A-R2C) is set to restart enabled, the output will be ON while the
fault restart function is in progress. See page 90 for the setting of (Sn-30~Sn-32).
