sensor (2000 [Ohm] at
25 [°C]).
n
Inform your service agency.
• Check software version.
• Exchange drive control board.
n
Inform your service agency.
• Check the control and
cabling of the pulse release.
• Check Uz.
• If the power supply is not
regenerative: Is the braking
resistor connected?
• If the power supply is
regenerative: Is energy
recovery activated?
• Check the grounding and
shielding of the cable.
