Run Command

Output Frequency
After a stop is initiated, a subsequent Run commands input before the Minimum Baseblock Time (L2-03)
IMPORTANT
has expired, will be ignored.
2: DCInj to Stop: When the Run command is removed, the Drive will Baseblock (turn off its output) for the Minimum
Baseblock Time (L2-03). Once the Minimum Baseblock Time has expired, the Drive will inject DC current into the motor
windings to lock the motor shaft. The stopping time will be reduced as compared to Coast to Stop. The level of DC
Injection current is set by parameter b2-02 (50% Default). The DC Injection brake time is determined by the set value in
b2-04 and the output frequency at the time the Run command is removed.

If an overcurrent (OC) fault occurs during DCInj to Stop, lengthen the Minimum Baseblock Time (L2-03)
IMPORTANT
until the fault no longer occurs.
3: Coast w/Timer: When the Run command is removed, the Drive will turn off its output and the motor will coast to a stop.
If a Run command is input before time T (operation wait time) expires, the Drive will not run and the Run command will need
to be cycled before operation can occur. The time T (operation wait time) is determined by the output frequency when the Run
command is removed and the active deceleration time (C1-02).
