<1>  Access Levels  A: Advanced Programming Menu  Q: Quick Setting Menu  -: N/A in this Control Mode 
<4>  Default Setting is determined by the control method (A1-02 or E3-01) 
<8>  Setting Range is determined by the control method (A1-02) 
<11> When the frequency reference is reduced just below S4-01, -02, -12, -13 and no STOP command is entered, the drive will continue to run using the 
FWD frequency reference of S4-01 or -12, whichever is larger, or the REV frequency reference of S4-02 or -13, whichever is larger. 
<12> For a more detailed description of the Crane Software sequence faults, see section 7.1.6. 
<13> When operating in OLV control mode without a counter weight, be sure to set S1-20 parameter to 1.
