4.1.2 Calibration of the AM-5 Output
Preparation
(1)
Connect a meter (frequency meter) of 0-IOVDC across inverter
terminals AM-5. (Note the polarity. AM is the positive terminal.)
(2) Set any of 101 to 103, 105, 106, 108, 110 to 114, 117and 121 in Pr.

to the corresponding mode.
Note:
This calibration (Pr. 901) is
only valid when any of 101 to
103, 105, 106, 108, 110 to
114, 117 and 121 has been
set in Pr. 54 or the required
value set in Pr. 158 to output
a signal to terminal AM.
When any other value has
been set (signal output to
terminal FM has been se-
lected i n Pr. 5 4 ) , the ab-
sence of Pr. 901 is displayed
on the screen as soon as this
parameter is selected by the
above operation.
