OC1 q 011 Short-circuit
Short-circuit. Find out cause of short-circuit; check cable.
Excessive capacitive charging current of the motor
cable.
Use motor cable which is shorter or of lower
capacitance.
OC2 q 012 Earth fault
One of the motor phases has earth contact. • Check motor
• Check supply module
Excessive capacitive charging current of the motor
cable.
Use motor cable which is shorter or of lower
capacitance.

OU q 020 Overvoltage Excessive brake energy (DC bus voltage higher than
set under C0173).
Use brake module or energy recovery module.
P01 q 151 Limit switch negative Negative limit switch was reached. • Control drive in positive direction
• Check terminal connection X5/E2.
P02 q 152 Positive limit switch Positive limit switch was reached. • Control drive in negative direction
• Check terminal connection X5/E1.
P03 q 153 Second contouring error
Phase difference between set and actual position is
larger than the contouring error limit set under
C0255.
• Extend contouring error limit under C0255
• Switch off the monitoring if necessary (C0589 =
3).
Drive cannot follow the digital frequency (I
max
limit). Check drive dimensioning.
P04 q 154 Negative position limit Negative position limit (C1224) was not reached. Find out why the value was not reached (e.g.
”incorrect” position targets, set function position
value) and adjust the negative position limit (C1224)
if necessary.
P05 q 155 Positive position limit Positive position limit (C1223) was exceeded. Find out why the value was exceeded (e.g.
”incorrect” position targets, set function position
value) and adjust the positive position limit (C1223)
if necessary.
P06 q 156 No reference The homing point is unknown. For absolute
positioning no homing was performed before the
first positioning.
Perform one of the following functions and restart:
• Manual homing.
• Start homing in the program.
• Set reference.
