Precautions for Correct Use
When the Drive Programming program is stopped, the status of the analog input terminal vari-
ables is not retained but updated according to the status of actual input terminals.
Analog Output Terminal Variables YA(0) to YA(2)
You can use the inverter's multi-function digital output (PWM output) FM terminal, the multi-function
analog output (voltage output) AM terminal and the multi-function analog output (current output) AMI ter-
minal as the analog output terminal variables YA(0) to YA(2) of the Drive Programming function.
You can continuously monitor the status of the analog outputs regardless of the parameter settings.
To control the analog outputs via the Drive Programming function, select Drive Programming for the
setting of the inverter parameters FM Selection (C027), AM Selection (C028) and AMI Selection
(C029).

• The analog output terminal variables YA(0) to YA(2) are unsigned 1-word variables.
• Set the variables in increments of 0.01% as a percentage of the maximum output duty, 10 V or 20 mA.
• Select Drive Programming for the setting of the inverter parameters FM Selection (C027), AM Selec-
tion (C028) and AMI Selection (C029) to control the analog output terminals via the Drive Program-
ming function. Even if you do not select Drive Programming for the parameters, it is possible to
monitor the status of the analog output terminals.
