High -speed maximum frequency limit
q q
Maximum limit frequency can be set to a frequency higher than 120Hz for
exceptionally high-speed operation.
The maximum frequency limit set by the
1 st function is overriden by this
setting.
ELECTRONIC THERMAL RELAY SETTING
Electronic thermal relay .191
To protect the motor from overheating, motor rated current value can be set
directly in amperage.
When the inverter is shipped, it is set to the rated output current of inverter.
For FR-Z220-0.4K and 0.75K, however, it is set to 85% (Amp.) of the rated
output current of inverter.
FR-Z220-0.4K . . . . . 2.6A
FR-Z220-0.75K
. . . . . 4.3A
For models larger
than FR-Z220-1.5K, the factory setting is the rated output
current in accordance with the standard specification (see P. 61) .
ACCELERATION/DECELERATION TIME SETTING
Acceleration time

Deceleration time a
Acceleration/deceleration time can be set
within the range from 0.1 sec. to 3,600 sec.
Acceleration time is the time taken for
acceleration to output frequency (fm> set
