This is the reference value for the over current limit,
OLT, current % display, analog input and output.
Note:
Speed Reference Selection: Enable below require parameter as per source of frequency reference
A00-0 – Local Set Frequency (Keypad of Axpert-VT240S)
C03-D to F – Frequency Reference Input (Analog I/O i.e. 0~10V, 4~20mA and others)
I/O's Requirements: Enable below parameter as per requirement.
C03-0 to C03-C and C13-0 to C13-6 for Digital I/O and C12-0 to C12-F and C14-0 to C14-B for Analog
I/O.

= 30 to 120 Sec. (30kw to 75kw)
= 70 to 200 Sec. (90kw & 200kw)
= 100 to 270 Sec. (250kw & above)
Note: Acceleration time should be in the range of 1/3 to
2/3 times of deceleration time settings.

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
blower 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.
C21-2 Peak-Up wait time
Sec 2.0 0.5 10.0 Increase C21-2 If it not catching the rotating speed
