4-2 Function Mode AM Adjustment You can adjust the analog voltage (0 to 10 V DC) from the AM terminal on the control terminal block. 4 AM output 10V Adjust the gain with reference to voltage at 0% b080 Functions Adjust the offset. (Parallel shift) C086 0 100% Output frequency or output current Note: If the offset (C086) is changed, the point to reach 10 V changes accordingly because of par- allel movement. To avoid this, adjust the offset (C086) before the gain (b080). Starting Frequency •Set the frequency for starting Inverter output when the RUN signal is turned on. •Use mainly to adjust the starting torque. •With the starting frequency set high, the starting current increases.
Therefore, the current may exceed the overload limit and cause an overcurrent trip. 4-31 Parameter No. Function name Data Default setting Unit b080 AM adjustment 0. to 255.
