5. PARAMETERS
5.2 (E) Environment setting parameters
• When setting dial and key operations are disabled, "
" appears on the operation panel. If setting dial or key
operation is attempted while dial and key operations are disabled, "
" appears. (When a setting dial or key
operation is not performed for 2 seconds, the monitor display appears.)
• To enable the setting dial and key operation again, press
for 2 seconds.
NOTE
• Even if setting dial and key operations are disabled, the monitor indicator and
are enabled.
5.2.6
Using a 600 VAC power supply
To use a 600 VAC power supply, change the voltage protection level.
• To use a 600 VAC power supply, set
Pr.977 Input voltage mode selection
= "2". The setting is applied after converter
reset. Parameter clear or All parameter clear must be performed after resetting the converter unit.
• Setting
Pr.977
= "2" changes the voltage protection level to the one for the 600 VAC class.
5.2.7
Parameter write selection
Whether to enable the writing to various parameters or not can be selected. Use this function to prevent parameter values from
being rewritten by misoperation.
•
Pr.77
can be set any time. (Setting through communication is unavailable.)
Disabling parameter write (Pr.77 = "1")
• Parameter write, Parameter clear, and All parameter clear are disabled. (Parameter read is enabled.)
• The following parameters can be written even if
Pr.77
= "1".
Writing parameters (Pr.77 = "2")
• These parameters can always be written.
