CP-Parameters
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 re-
duced 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 eld 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.
CP.28 Display Reaction Restart
0 E.dOH Immediate disabling of modulation
Remove fault;
reset
1* A.dOH Quick stop / disabling the modul. after reaching
speed 0
2* A.dOH Quick stopping / holding torque at speed 0
3 A.dOH Immediate disabling of modulation
Autoreset, if no
fault is present
4* A.dOH Quick stop / disabling the modul. after reaching
speed 0
5* A.dOH Quick stopping / holding torque at speed 0
6* none No effect to the drive; With CP.31/32 an external
module can be controlled (e. g. fan)
inapplicable
7 none No effect to the drive; Malfunction is not present!
External temperature monitoring is not activated.
*) If the motor is still too hot after 10 seconds, the error E.dOH is triggered and the mod-
ulation is switched off!
CP.29 Analog output 1 / function
CP.29 denes the function of analog output 1.
