Digital Operator Functions
The digital operator enables the following:
(1) Control Signal Status Display
The status of the control signals for each unit is displayed by
monitoring the operation status. For the display items, see
APPENDIX 5.
(2) Control Constants Display and Setup
Control constants must be set up for normal operation in compli-
ance with the specifications. APPENDIX 6 lists the control con-
stants.
(3) Protective Functions Display
If an error occurs during operation, protective functions are dis-
played. (Refer to Tables 18 to 20.) These are not displayed when
operation is normal.
(4) Digital Operator Function
Stand-alone operation without sequence input signals or speed
reference is possible. This function is effective for the test run of
the inverter/converter connected only to a motor.
