CP-Parameter
CP.24 Max. ramp current
This function protects the frequency inverter against switching off through overcurrent during
the acceleration ramp. When the ramp reaches the adjusted value,it is stopped so long until
the current decreases again. CP.3 displays "LAS" at active function.
CP.25 Max. constant current
This function protects the frequency inverter against switch off through overcurrent during
constant output frequency. When exceeding the adjusted value, the output frequency is
reduced until the value drops below the adjusted value. CP. 3 displays "SSL" at active
function.
CP.26 Speed search condition
When connecting the frequency inverter onto a decelerating motor, an error can be triggered
by the differing rotating field frequencies. With activated speed search the inverter searches
for the actual motor speed, adapts its output frequency and accelerates with the adjusted
ramp to the given set value. During speed search CP.3 displays "SSF". The parameter
determines, under what conditions the functions operate.
In case of several conditions the sum of the value must be entered. Example: CP.26 = 12
means after reset and after auto-reset UP.
Value Condition
0 Function off
1 at control release
2 at switch on
4 after reset
8 after Auto-Reset UP
CP.28 Response of external overtemperature
CP.28 determines the response of the drive on the external temperature monitoring. At
factory setting the function is switched off. In order to activate this function the power circuit
terminals T1/T2 must be connected. After that the response can be adjusted according to
following table. If overheat no longer exists, the message E.ndOH (or A.ndOH) is output.
Only then the error can be reset or the automatic restart can be carried out.
