Outputting Monitor Data by Analog Output

 How to output the inverter monitor data externally by analog output?
Q
 The [Ao1] terminal is an analog voltage output terminal from 0 to 10 VDC. Output frequency and
A
output current can be monitored.
 Analog output may not be stable immediately after power-on or power interruption.

*1. "LAD frequency (07)" is the frequency commanded by the inverter and corresponds to "Output
frequency monitor [d001]". "Output frequency (00)" is a value that takes into account vector control
compensation and stabilization control such as sensorless vector control. "Output frequency" output
may appear unstable at low speeds during overload limit deceleration, etc. In this case, changing it to
"LAD frequency" results in a better stability.
*2. When "Speed feedback" is set for "Pulse input, target function selection [P003]", "Speed detection value
monitor [d008]" is outputted.
*3. Valid only when the control method is sensorless vector control.
*4. When "Frequency conversion gain [b086]" is set, a converted value is outputted for the digital output
frequency.
*5. For details on YA(1), refer to the "Easy-Sequence Function (EzSQ) Programming Guide (NT2021*X)".
*6. Specifications of output torque (signed) are as follows.
