Terminals T1, T2 are not assigned. Connect PTC or thermostat or switch off monitoring
(C0585=3).
OU x020 Overvoltage Excessive brake energy (DC bus voltage higher than
set under C0173).
Use brake module or energy recovery module.
P01 x151 Limit switch negative Negative limit switch was reached. • Control drive in positive direction
• Check terminal connection X5/E2.
P02 x152 Positive limit switch Positive limit switch was reached. • Control drive in negative direction
• Check terminal connection X5/E1.
P03 x153 Following error
Phase difference between set and actual position is
larger than the following error limit set under
C0255.
• Extend following 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 x154 Nega tive position limit Negative position limit (C1224) was not reached. Before starting again, find out why the limit was not
reached (e.g. ”incorrect” position targets, setting of
position value function) and adapt the negative
position limit (C1224).
P05 x155 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 x156 No reference The reference point is not known. In case of the
absolute positioning, no homing was carried out
before the first positioning.
Perform one of the following functions and restart:
• Manual homing.
• Start homing in the program.
• Set reference.
P07 x157 PS Absolute mode
instead of relative mode.
An absolute PS (C1311) was performed during
relative positioning (position mode C1210).
Perform one of the following functions and restart:
• Change from absolute PS to relative PS.
• Change position mode.
P08 x158 Actual offset out of
range
Actual reference dimension offset (C1226) outside
the position limits. Error of the program function
”set position value”.
If necessary, adapt the position limit values or
check whether the program function ”set position
value” is to be applied.
