Figure 16. DC Injection Braking to Stop
Important: If an overcurrent (OC) fault occurs during DCInj to Stop, lengthen the Minimum Baseblock Time (L2-03) until the fault no
longer occurs.
3: Coast w / Timer: When the Run command is removed, the iQpump 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 iQpump 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).

◆ b1-07 Local / Remote Run Selection
Note: Used with LCD Operator only.
◆ b1-08 Run Command Selection During Programming
As a safety precaution, the iQpump drive will not normally respond to a Run input when the digital operator is being used to adjust
parameters. If it is necessary that external Run commands be recognized even while the drive is being programmed, set b1-08 = “1:
Enabled.”
