This speed sensitive protective feature interrupts the motorcurrent to protect the motor wiring and windings in the event of overload, eliminating theneed for an external overload device. When multiple motors are used with a single drive,separate overload devices are required to properly protect the individual motor branches.9. Press the key until back at the Top Screen. ⇒Step Display/Result1. Select H4-02 or H4-03 by pressing the and keys. ⇒2.Press the key while the drive is stopped and the followingvoltage is output for adjustment: output voltage = (10 V x OutputGain (H4-02) + Output Bias (H4-03). Using this output, adjustoutput gain (H4-02) and output bias (H4-03).⇒Step Display/ResultOutput Voltage10Gain V10 V100%0%0 V MonitorContents100(%)10Bias V100(%)
