4-2 Function Mode Refer to "Analog Output AM Terminal" (page 4-75). AM output 10V Adjust the gain with reference to voltage at 0%. b080 Adjust the offset. (Parallel shift) C086 0 100% 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). Output frequency or output current 4 Starting Frequency Functions Set the frequency to start Inverter output with the RUN signal 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.
Carrier Frequency You can change the PWM waveform carrier frequency output from the Inverter. •With the carrier frequency set high, you can reduce metallic noise from the motor. However, this may increase noise or leakage current from the Inverter. •Carrier frequency adjustment also helps avoid mechanical or motor resonance. 4-36 Parameter No. Function name Data Default setting Unit b082 Starting frequency 0.5 to 9.9 1.5 Hz FW Output frequency b082 Output voltage Parameter No. Function name Data Default setting Unit b083 Carrier frequency 2.0 to 12.0 3.0 kHz
