1-5-2 Setting Before Operation
Since the standard Inverter Models are shipped with the default
values listed in
2-7 Function/Constant List, the Digital Operator
must be used in order to change the constants from the initial val-
ues to values in accordance with the load specifications.
The following describes the functions and initial constant set val-
ues which are often used for operation.
Output Frequency and Accel/Decel Time:
The maximum output frequency is set to 60 Hz and accel/decel
time to 10 seconds at the factory prior to shipping. To change the
values, refer to
2-8-6 Accel/Decel Time and Patterns.
