t overcurrent limit
6 Operating status messages
a.c. VFD: I 2 t limit has triggered, e.g. > 1.5 x I
note P504)
• Continuous overload at VFD output
• Possible encoder fault (resolution, defect,
connection)
2 t Brake chopper: I 2 t limit has activated, 1.5 times values
reached for 60 s (please also pay attention to P554, if
present, and P555, P556, P557)
• Avoid overcurrent in brake resistance
Derating (output reduction)
• 125% overcurrent for 50 ms
• Brake chopper current too high
• For fan drives: enable flying start circuit (P520)
Derating (output reduction)
• 150% overcurrent
• Brake chopper current too high
Error signal from module (short duration)
• Short circuit or ground fault at VFD output
• Motor cable is too long
• Use external output choke
• Braking resistor faulty or resistance too low
 Do not switch off P537!
The occurrence of a fault can significantly shorten the
service life of the VFD or even destroy it.
P537 (pulse current switch-off) was reached 3x within 50 ms
(only possible if P112 and P536 are disabled)
• VFD is overloaded
• Drive sluggish, insufficiently sized,
• Ramps (P102/P103) too steep -> Increase ramp time
• Check motor data (P201 ... P209)
for 60 s (also
