4.1 Overcurrent measurement
"Overcurrent measurement"
Warning: pulse switch off is active
The limit for activation of pulse switch off (P537) has been
reached (only possible if P112 and P536 are switched off)
• FI is overloaded
• Drive sluggish, insufficiently sized
• Ramps (P102/P103) too steep -> Increase ramp time
• Check motor data (P201 … P209)
• Switch off slip compensation (P212)

12.1 Motor Limit / Customer
"Motor switch-off limit"
Warning: 80 % of the drive switch-off limit (P534 [-01]) has
been exceeded.
• Reduce load on motor
• Set higher value in (P534 [-01]).
12.2 Generator limit
"Generator switch-off limit"
Warning: 80 % of the generator switch-off limit (P534 [-02])
has been reached.
• Reduce load on motor
• Set higher value in (P534 [-02]).
12.5 Load monitor
Warning due to overshooting or undershooting of
permissible load torques ((P525) … (P529)) for the time set
in (P528).
• Adjust load.
• Change limit values ((P525) ... (P527)).
• Increase delay time (P528).
