Terminals T1, T2 are not assigned. Connect PTC or thermostat or switch off monitoring
(C0585=3).
OU 20 Overvoltage Excessive brake energy (DC bus voltage higher than set
under C0173).
Use brake module or energy recovery module.
P01 151 Limit switch negative Negative limit switch was reached. l Control drive in positive direction.
l Check terminal connection X5/E2.
P02 152 Positive limit switch Positive limit switch was reached. l Control drive in negative direction.
l Check terminal connection X5/E1.
P03 153 Contouring error
Phase difference between set and actual position is
larger than the contouring error limit set under C0255.
l Extend contouring error limit under C0255
l Switch off the monitoring if necessary (C0589 = 3).
Drive cannot follow the digital frequency (I
max
limit). Check drive dimensioning.
P04 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 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 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:
l Manual homing.
l Start homing in the program.
l Set reference.
