Parameter
Adjustment method of torque setting voltage (current) bias and gain
1.Method to adjust any point by application of voltage (current) to across the terminals 1-5 (4-5).
The following example illustrating the procedure assumes that Pr. 241 is set to "0".
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).
Press the MODE key to choose the parameter
setting mode.
Turn the digital dial until "C..." appears.
Press the SET key to display "C---".
Turn the digital dial until "C 1 9 (C 4 1 )"
appears. Set to C19 Terminal 1 gain (torque).
Press the SET key to display the analog voltage
(current) value (%).
Apply the maximum set value. (Turn the external
potentiometer to its maximum)
CAUTION:
After performing the operation in step
not touch the digital dial until completion of
calibration.
Press SET to set.
By turning the digital dial, you can read another parameter.
Press the SET key to return to the "C---" indication (step
Press the SET key twice to show the next parameter (Pr.CL).

NOTE
Error code Er3 may be displayed when you save if torque setting value of gain and bias are
less than approx. 5% apart. If this happens correct the frequency settings and save again.
