C00-1 Run/stop method 2 1 2 Select coast to stop mode (C00-1=1), It is mandatory
when there is contactor or ACB in the output of the
drive.
C21-0 Number of retries 0 0 10 Allow restart 2 or 3 time in fault condition to continue fan
operation.
Note: Consult to customer before changing this
parameter as motor (load) will restart automatically in
case of tripping /power failure of VFD.
C04-D
PICK Peak-Up 0 -11 16 It is mandatory to enable speed search to start the VFD
at rotating speed of the motor as load is rotating for a
longer time due to load inertia to avoid any tripping while
restarting.
Take a start/stop trial with loaded motor at 4 different
rotating speeds (standstill, 5Hz, 20Hz, and 50 Hz) of the
actual rotor by keeping coast to stop & make sure that
rotating speed is caught by the VFD.
