Description LCP name
0x7182 Brake resistor power limit Error Brake resistor power limit exceeded.
The power transmitted to the brake
resistor is calculated as an average
value over the last 120 s of run time.
The calculation is based on the DC-link
voltage and the brake resistor value set
in parameter 2-16 (Brake resistor power
120 s). The error is reported when the
value is exceeded within 120 s.
