Frequency setting by analog input (terminal 2, 4) Parameter
6 - 188
2. Method to adjust any point without application of a voltage (current) to across terminals 2-5 (4-5).
(This example shows how to change from 4 V to 5 V, assuming that Pr. 241 is set to "1".)

Fig. 6-97: Bias and gain adjustment without application of an reference signal
NOTE
By pressing the digital dial after step
햷
, you can confirm the current frequency setting bias/gain
setting. It cannot be confirmed after execution of step
햸
.
Operation Display
Analog voltage (current) value (%)
across terminals 2-5 (across terminals
4-5) and the "A" indication or no
indication is lit.
The gain frequency is reached when a
voltage of 5.0 V is displayed.

(Adjustment completed)
앫
By turning the digital dial, you can read another parameter.
앫
Press the SET key to return to the "C---" indication (step
햵
).
앫
Press the SET key twice to show the next parameter (Pr.CL).
햲
Confirmation of the RUN indication and
operation mode indication.
The inverter must be at a stop.
The inverter must be in the PU operation
mode (using the PU/EXT key).
햳
Press the MODE key to choose the
parameter setting mode.
햴
Turn the digital dial until "C..." appears.
햵
Press the SET key until "C---" appears.
햶
Turn the digital dial until "C 4 (C 7)"
appears. Set to C4 "Terminal 2 frequency
setting gain".
햷
Press the SET key to display the analog
voltage (current) value (%).
햸
Turn the digital dial to set the gain of the
voltage signal value. If Pr. 241 is set to "1"
the value will be displayed directly.
CAUTION:
When you start turning the digital dial
the value that is currently stored
(in this example 4 V) will be displayed.
햹
Press the SET key to set.
PRM indication is lit.
The parameter number read
previously appears.
C1 to C7 setting is enabled.
