Table 5.10 Speed Reference Priority and Jog Frequency
Setting 7: Accel/decel ramp selection 1
Switches between accel/decel times 1 (C1-01 and C1-02) and 2 (C1-03 and C1-04). Refer to C1-01 to C1-08: Accel,
Decel Ramps 1 to 4 on page 172 for details.
Setting 8, 9: Baseblock command
When the drive receives a baseblock command, the output transistors stop switching, the motor coasts to stop, and a bb
alarm flashes on the digital operator to indicate baseblock.
WARNING! Sudden Movement Hazard. When using a mechanical holding brake with the drive in a lifting application, close the brake
when the drive output is cut off by a baseblock command triggered by one of the input terminals. Failure to comply will result in a
slipping load from the motor suddenly coasting when the baseblock command is entered and may cause serious injury or death.
Setting F: Not used (Through mode)
Select this setting when the terminal is not used or when using the terminal in the pass-through mode. When set to F, an
input does not trigger any function in the drive. Setting F, however, still allows the input status to be read out by a PLC via
a communication option or MEMOBUS/Modbus communications.
Setting 14: Fault reset
When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to
stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the
Up/Down command, clear the fault either by pressing the RESET key on the digital operator or closing a digital input
configured as a Fault Reset (H1- = 14).
Note: Remove the Up/Down command prior to resetting a fault. Fault Reset commands are ignored while the Up/Down command is
present.
Setting 15, 17: Fast Stop (N.O., N.C.)
The Fast Stop function operates similar to an emergency stop input to the drive. If a Fast Stop command is input while the
drive is running, the drive decelerates to a stop in the deceleration time set to C1-09 (Refer to C1-09: Fast Stop Ramp on
page 173). The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast Stop input, and
switching off the Up/Down command.
• To trigger the Fast Stop function with a N.O. switch, set H1- = 15.
• To trigger the Fast Stop function with a N.C. switch, set H1- = 17.
