33 Two Stage Acceleration and Deceleration When terminal [2CH] is turned ON, the inverter changes the rate of acceleration and deceleration from the initial settings ( F002 and F003 ) to use the second set of acceleration/ deceleration values. When the terminal is turned OFF, the inverter is returne...

34 Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protection (USP) function prevents that automatic startup, so that the inverter will not run without outside intervention. When USP is...

35 Reset Inverter The [RS] terminal causes the inverter to execute the reset operation. If the inverter is in Trip Mode, the reset cancels the Trip state. When the signal [RS] is turned ON and OFF, the inverter executes the reset operation. The minimum pulse width for [RS] must be 12 ms or greater. ...
