Note:
◆
The ac drive output and instrument systems are likely to produce bias, you can adjust
the output gain (AO1or AO2) for the meter calibration and the change of measuring
range.
◆
To avoid fluctuations of output in calibrating, you can make the ac drive output a
standard signal (set P4.17 or P4.18 to 5 to get DC 5v. It is 50% of the full range) for
AO gain calibration. For example, to calibrate AO1, select the function code P4.22
and press “ENTER” key to enter into the function parameter menu, turn encoder on
the keyboard right
+
or left
-
to set output signal just to 5 VDC. The
modification of P4.22 is valid immediately, and would be saved into P4.22 after
pressing ENTER key. To calibrate AO2 is like the above.
◆
If the external instrument has a great bias, the instrument should connect to the ac
drive and carry out the actual adjustment.

Note:
◆
Single cycle 1
The ac drive stops automatically after one cycle of operation and will start when
receiving RUN command again. As shown in Fig. 5-5-1.
